What is a neuropsychologist?

A neuropsychologist is a psychologist who specializes in understanding the relationship between the physical brain and behavior. The brain is complex. Disorders within the brain and nervous system can alter behavior and cognitive function.

According to the University of Rochester Medical Center, the role of a neuropsychologist is to understand how brain structures and systems relate to behavior and thinking.

Neuropsychologists have a doctorate in psychology and training in neuropsychology. They often work in research or clinical settings.

What does a neuropsychologist do?

Neuropsychologists evaluate and treat people with various types of nervous system disorders. They work closely with doctors, including neurologists.

Illnesses, injuries, and diseases of the brain and nervous system can affect the way a person feels, thinks, and behaves. Symptoms that may call for a neuropsychologist include:

  • memory difficulties
  • mood disturbances
  • learning difficulties
  • nervous system dysfunction

If other doctors can’t identify the cause of a symptom, a neuropsychologist can help determine a diagnosis. If a diagnosis is already known, an assessment can still be helpful.

A neuropsychologist can help determine what impairments you might have and how severe they are. The following are examples of conditions they evaluate and treat:

  • A stroke can affect behavior, thinking, memory, and other brain functions in obvious or subtle ways. They can perform an evaluation to help determine the degree of stroke impairment.
  • Parkinson’s disease, a progressive disorder, can cause several neurological problems. A neuropsychologist’s exam can provide a baseline to help them determine disease progression and decreased function.
  • Alzheimer’s disease and other types of dementia can interfere with memory, personality, and cognitive abilities. A neuropsychologist can perform an exam to help them identify it in its early stage.
  • Traumatic brain injuries can cause a wide variety of symptoms. A neuropsychologist can help determine how an injury affects functions like reasoning or problem-solving skills.
  • A neuropsychologist can help determine which of the many types of learning disabilities someone has and develop a treatment plan.

Typical neuropsychological procedures

The nervous system is complex. Neuropsychologists use different types of procedures to identify problems and treatment plans. Typical procedures they perform include:

Neuropsychological evaluation

This evaluation is an assessment of how your brain functions. The evaluation will include an interview and questions that will help outline your performance of daily tasks, as well as identify memory issues and mental health concerns. The interview will also cover information on symptoms, medical history, and medications you take.

An evaluation includes different types of standardized tests to measure many areas of brain function, including:

  • memory
  • cognitive ability
  • personality
  • problem-solving
  • reasoning
  • emotions
  • personality

Brain scans, such as CT or MRI scans, can also help a neuropsychologist make a diagnosis.

Understanding results

Your neuropsychologist will compare your test results with those of other people with a similar education and age.

Evaluation and test results may help determine the cause of an issue when other methods don’t work. Tests can even help identify mild thinking and memory issues, which may be subtle.

Neuropsychologists help develop a treatment plan by understanding how the brain functions and how that functioning relates to behavior. Treatment plans may include medication, rehabilitation therapy, or surgery.

Outlook

A neuropsychologist can help diagnose a cognitive, behavioral, or neurological condition. Seeing a neuropsychologist and completing their tests can lead to a deeper understanding of your condition. When other doctors might not be able to diagnose an issue, consider seeing a neuropsychologist.

What Is Hemianopsia and Why Does It Happen After TBI?

Diagnosing Vision Problems After a Brain Injury

Testing Brain Injury-Related Vision Issues with People Who Can’t Communicate

Out of all of our senses — seeing, hearing, smelling, tasting, feeling — vision is our most dominant sense. Researchers estimate that 80-85 percent of our perception, learning, and cognition are mediated through our eyes. So dealing with vision issues after a brain injury can be challenging.

Common forms of vision problems

In general, 20-40 percent of people with traumatic brain injury (TBI) experience related vision disorders. Some vision-related issues can be permanent; others resolve quickly. This depends on the individual and his unique brain injury.

Vision can be broken down into the following general categories:

  • Visual motor abilities, including alignment, refer to “eye posture” — meaning the direction in which the eyes point. For example, if the eyes are straight and aligned, the eye posture is normal.
  • Visual perception is the ability to interpret information and surroundings from visible light reaching the eye.
  • Visual acuity refers to clarity of sight.
  • Visual field is the complete central and peripheral range, or panorama of vision; picture a pie as your visual field. Here are the common types of visual field loss:
    • hemianopsia
    • quadranopsia
    • homonymous hemianopsia
    • bitemporal hemianopsia

What happens with change or loss of vision?

When we can’t see clearly or have lost part of our field of vision, everyday tasks can become more challenging, some even impossible.You might have trouble with reading, driving, dealing with bright lights, or doing activities that involve hand-eye coordination. In many cases, there are tools and strategies that can help.

Techniques and compensatory strategies

In rehab, there are various techniques and strategies to help people with vision problems after TBI. They can include:

  • Wearing prescription glasses
  • Using magnification
  • Implementing better or varying lighting for different environments
  • Using assistive technologies to help make reading and using a computer easier
  • Learning to use scanning and head turning
  • Re-teaching the eyes to move and look into missing areas in the vision field

Getting the right professional help

Someone with vision problems after a TBI should find a top-notch ophthalmologist or neurologist who can administer a comprehensive vision exam. From there, the ophthalmologist may suggest the patient work with an interdisciplinary rehabilitation team to integrate all the necessary treatments for optimal recovery.

Having vision problems after a TBI can definitely interfere with a person’s quality of life, but it doesn’t have to be that way. Vision expert Dr. Gregory Goodrich advises, “Even if your symptoms don’t seem that serious, try to find an optometrist or ophthalmologist who has experience working with people with TBI. And keep persisting until you get the help you need.”

[WEB PAGE] What Life Is Like With a Brain Injury

An acquaintance recently asked my husband if he thought I was “faking” my brain injury. I thought this remark hit a bit higher on the offensive meter than the typical “she looks fine” and “I forget words sometimes too, that’s just old age.” This one digs sharply into the pit of my stomach. I don’t fault others for not understanding. Everyone has their own problems, and there’s not a lot of awareness about post-concussion syndrome and traumatic brain injury. Even my own husband, who patiently takes care of me day after day, struggles to fully grasp what it’s like. I look “normal” on the outside. I’m like a duck sitting on a pond; no one else can see my feet frantically paddling just to stay afloat.

The past year of my life has been the most challenging yet, and while I have often been treated with kindness and compassion, I have also felt very alone on my road to recovery. The other parents who see me drop my kid off at school don’t know I’m wearing ear plugs to drown out the unbearable noise; they don’t know that I can’t drive on the highway because I panic at speeds above 60 mph. My neighbors who see me walk the dogs can’t tell that I lose my “ish” whenever the leashes get twisted. Friends who saw my post of my daughter’s breakdancing performance have no idea that I spent four days in bed afterward from the over-stimulation of my brain. Even readers of my blog may not know that it takes me much longer than it should to write an article because screen time gives me headaches, and my brain now struggles with sentence structure, word recall and spelling.

So here is my attempt at describing my brain injury, what it feels like to have the universe tell you that you can’t do anything you enjoy, and what it’s like to fear you’ll never again be able rejoin the outside world. For my brain-injured readers, I hope you feel a little less alone.

My brain injury is:

Like waking up one day to find you are suddenly a complete stranger in your body. Like your brain has been taken over by a tiny gremlin who is tripping wires and setting little fires.

Forgetting day after day after day when you turn the tea kettle on. Feeling perplexed each time you try to open the tea box. Leaving your sink water running after you get distracted by something else. Spooning salsa into your coffee. The few seconds after your timer goes off and you can’t remember what you set the timer for in the first place.

Calling your daughter by your dog’s name and not being able to recall the word “dog.” Jumbled sentences and made-up words. Stuttering or repeating the first word of a sentence like a broken record because you can’t find the next word when you are tired and overwhelmed.

Never being able to finish a task all at once. Cleaning, baking, emails, bills, personal grooming: all unfinished. Every task must be done in steps because there’s never enough brain energy. No longer being able to push through the exhaustion to finish a project, or else you will have symptoms for days.

Wearing your pajamas to the doctor because you can’t be bothered to get dressed. Can’t remember the last time you flossed.

A thought unfinished, a word unsaid. A blank space where the memory should be. You go to grab it, and it’s just not there. Not remembering where you parked your car or what you did yesterday, momentarily not recognizing your surroundings, forgetting to eat. Someone reminds you of something you forgot and there’s no spark of recollection.

The sense that you are “losing your mind,” a glimpse at what it’s like to have dementia. Feeling like you are sleepwalking through each day. Can’t think, can’t reason, can’t be logical or rational.

Time contracts and expands. You lose track of time, can’t calculate hours. You struggle to figure out how to structure your day, and it feels so overwhelming when you have more than two things you must do.

Vivid dreams and restless sleep. Panic rising before your sleep medicine kicks in. Dreams of getting lost and then not being able to remember your husband’s phone number. Dreams that people confuse your brain injury for mental illness. Recurrent dreams of wild animals attacking.

Always being in fight-or-flight mode; your sympathetic nervous system is on overdrive. Prey looking out for a predator. What was that movement in your peripheral vision? Will I slip and fall on the stairs? You imagine a tragic car accident while you’re driving. An unexpected noise makes you jump out of your skin.

You can’t quiet your mind and turn off the mental chatter. You’re easily distracted, concentration is impaired, you can no longer follow conversations. The grocery store is a nightmare with all of the lights, noise and endless choices.

A black empty feeling on the really bad symptom days, like someone scribbled out your brain with a black marker. Offline, no spark, unable to process information. There’s absolutely nothing left. The world has tilted and you are slipping off the edge.

My brain injury symptoms are:

A multitude of headaches, all day, every day, sometimes in the middle of the night. Stabbing, pulsing, electrical snapping, brain squeezing. In the sinuses, across the forehead, cheekbone and the back of the skull. Migraines and headache hangovers. Anything that can give you a headache does. Your brain always feels like a pressure cooker, a helium balloon ready to pop.

Blurry vision, your eyes won’t focus at the same distance. Pain when you look up, double vision when you look down. Words float in and out of the page so you can’t read for more than a few minutes. Blinding lights with halos everywhere, you have to squint and shield your eyes even from the moon. No more driving at night, you keep the lights in the house down low.

Ringing in your ears, high-pitched screeching, sometimes a deep whistle like a train horn. A moment that you lose hearing in one ear when the whistling becomes too loud. The sound of your blood pulsing in your ear with your heart beat, you just want silence.

Sound hurts your head, gouges your brain. Your brain can’t filter out the background noise that just gets louder and louder. The sound of your toothbrush charging hurts your head, your child’s footsteps are stomping directly on your brain. You can’t hear anyone talking when the fan is on. No more music, no more public places. You wear ear plugs inside your house because you can’t handle the dogs barking or more than one person talking.

Wearing sunglasses to watch a TV show with your child, closing your eyes half the time because the movement and colors are too overwhelming. Too much movement disorients you and makes you dizzy. Bending over hurts your head and you see stars.

Bumping into walls, missing your lip when you drink. Your coordination is not the same anymore.

Mental exhaustion — the kind where you can’t form complete sentences, can’t remember what you started out to do, your eyes sting and burn, and your head feels too heavy to carry.

Too loud, too fast, too bright, too much. Stop talking, stop moving, turn off the lights, enough. All the world, just shut the f*$% up! Mornings, days, evenings in your bedroom with the door shut, eye mask on and ear plugs in. Desperately needing to block out the world until the symptoms subside. You did too much, you tried too soon. You can’t handle it, you’re not ready. It’s only been a year.

A brain injury is relentless emotional turmoil, a constant internal tug of war.

It is denial that your recovery will take that long or that you may have lingering symptoms for the rest of your life.

It is self-doubt and self-judgment. The shame of being broken and weak. You think, “I’m not smart anymore, I’m an emotional disaster, I don’t contribute anything. Why me? Why did I have to go snowboarding that day? Why didn’t I take better care of myself before this?”

A brain injury is perpetual conflicting emotions. You want to go, but you want to stay; you want to be with someone, but you want to be alone; you want to keep trying, but you want to give up. You are so tired of doing nothing yet you don’t feel like doing anything.

An everlasting feeling of inertia. The reluctance to move; you think, “Just let me lay here for another minute.” Irritation that you have to stop a task because you need to rest before the symptoms come.

So much uncontrolled anxiety, the lump in your stomach hardening into a rock, the squeezing in your throat. Heart pounding. Hands trembling.

Incessantly worrying about the bills. Not knowing if you’ll ever be able to work again. You can’t imagine being able to get through an eight-hour workday.

Fear. Gripping, intense, paralyzing fear. Always some level of underlying fear. Fear of falling, fear of a car accident, hitting your head, never getting better. Fear of leaving the house, of doing something you used to do because it might increase your symptoms. Fear this is as good as it’s going to get.

A brain injury is that flicker of irritability rising at the slightest provocation, an imprudent outburst toward your kid. Pent-up rage, frustration with your new limitations. Wanting to break something, but you don’t have the energy to clean it up. Wanting to scream or punch something but it hurts your head.

Feeling fragile, like something will easily break you. Feeling volatile, like a volcano on the verge of erupting. Unable to tolerate any stress, your meltdowns are frequent.

A brain injury is loss. Loss of your old self, your life expectations, your career, your goals and your hobbies. Loss of your freedom and independence.

It is inconsolable grief. Endless tears. Hopelessness and despair. Sometimes going to bed at night and wishing you wouldn’t wake up in the morning.

A brain injury is altered relationships, isolation and lost social skills.

It is the never-ending guilt of being a burden on your family, for causing them pain, for requiring sacrifices, for scaring them on the days you can no longer “hold it together.”

Your husband becomes your caretaker, you become his patient. You are fragile and dependent. You are no longer the lioness; your kid worries about you and wants to protect you. They dutifully run your errands; they rightfully lose their patience. Everyone is on edge.

A brain injury is missing your daughter when she’s away, only to find you are too exhausted to be around her when she gets home, and you shamefully count the minutes until her bedtime.

It is feeling disconnected from your family. They often leave you behind because they have to. They want to be with you, but they want the “old” you. You can no longer do the things you used to do to bond with them. You can’t go on date nights or anniversary trips with your husband. You can’t read to your daughter, and you miss her dance performances, play dates and doctors’ appointments.

You wonder if you’ll ever be able to take your daughter on a girls trip or to see a movie. Anticipate that you will never see another concert. Realize you will never go skiing, sledding or ice skating with your kid again.

No more fun. No more wine with dinner, no Friday night beers. No restaurants, family gatherings or parties. No reading books, no watching TV. No more dancing, yoga, music or theater.

A brain injury is isolation from the world; you’ve become a recluse. You leave the house because you are going stir-crazy, only to feel buds of panic rise as you want to immediately return home.

Friends no longer invite you to hang out. They don’t even check on you anymore. It’s long past the time when they think you should have fully recovered. You miss being social but think, “What’s the point?” It’s too much stimulation anyway. Your brain injury is like a bad ex: you can’t talk about anything else, and they don’t want to hear it anymore.

You discover a newfound social awkwardness. You can’t follow conversations because you get distracted by your symptoms or an unfamiliar word or an external stimulus. You can’t maintain eye contact anymore. You no longer have a prefrontal filter; you laugh when you shouldn’t, you swear when it’s inappropriate and you interrupt. You’ve become self-conscious and have social anxiety. You are inflexible; a last minute change in plans feels catastrophic, a cancellation devastating.

A brain injury is profound loneliness you’ve never before experienced. No one can really understand what you are going through. You desperately want to be acknowledged, heard, understood — even when you “don’t make sense.”

A brain injury is exhausting efforts at trying to recover when there’s no protocol to follow, no guarantee of healing.

Recovery happens in waves, sharp dips and long plateaus. Progress is measured in years. You may never fully recover.

A brain injury is appointment after appointment. Neurologist, chiropractor, craniosacral therapist, acupuncturist, naturopath, hyperbaric oxygen clinic, trauma counselor, vision therapist, nutritionist. You don’t have the energy to go to any of them.

Infrared light therapy, vestibular therapy, vision therapy homework, dry needling, meditation, brain exercises to stimulate neuroplasticity. Special glasses with eye lights, bone-conducting headphones, eye charts taped on the walls around the house. The different parts of your brain like an orchestra that’s out of tune.

Medications and supplements, pills and powders, sprays and injections. Gagging on healthy brain foods. Anything to heal. Desperate to tame.

Rest, rest; always more rest. Hour after hour of laying in silence. You are bored. Your body betrays your brain when it needs to rest. You resist. When your eyelids refuse to stay shut, you stare at the ceiling, listening to the tick of the clock and the hum of the furnace. Time stands still and then suddenly slips away.

A brain injury is transformation, a time of deep reflection and a new beginning.

A constant struggle to keep going. To not sink. To choose life after brain injury.

It is allowing yourself the time and space and rest you need to heal.

Countless hours spent contemplating your purpose and what crucial life changes you should make.

It is relinquishing control. Letting go of behaviors that didn’t actually serve you, and slowing down so you can pay attention to what really matters.

Cultivating gratitude and counting your blessings. Practicing self-compassion and self-acceptance. Forgiving your mistakes, pardoning your past. Finding a glimmer of humor beneath the dark shadows.

A brain injury is celebrating the smallest of victories. Finding your strength and becoming a warrior. An upheaval of your whole life, and then you climb off the edge and pave a new path.

It is waking up one day and realizing you are no longer a stranger in your life.

Follow this journey on Better Brained.

[BLOG POST] Life after a Brain Injury: Acknowledging your family & friends efforts

Life after a Brain Injury: Acknowledging your family & friends efforts

One of the biggest stressors that most brain injury survivors talk about is how relations between them and their circle of friends and family starts to show cracks. I have brought this up before in Breakdown of relationships after a brain injury and Advice for family of a recent TBI survivor. But there’s another important part that I want to take the time to address to try to help those cracks heal.

Previously I have explained how within a short period of time after my car accident, which caused my traumatic brain injury, my Dad was diagnosed with Alzheimer’s. As my Mum had sadly passed away just weeks after my accident, I needed to help Dad whilst he continued to try to live at home. Therefore, I was in the position of being the person who needed to be cared for, whilst supporting someone else who was also having cognitive difficulties. I hope you can see that I was in a position of getting a sense of what it’s like for a brain injury patient as well as the person who is trying to help them.

Forgive me; I warn you that you probably won’t like what I’m about to say.

Firstly, know that I am not shaming brain injury survivors for the issues that develop in their personal relationships. However, as Newton said in his third law of motion, “Every action has an equal and opposite reaction.” Now I know that’s about physics, but it can still relate to many parts of life. There are consequences for everything we do, and that includes how people feel as a result of our actions, even if we didn’t intend to affect them.

The sheer worry of what Dad was or wasn’t doing was turning me into a nervous wreck. I did my best not to show him, but then it meant it sometimes came out in frustration. I would be short with him and be overly blunt and direct with him about his errors. But he didn’t realise that I would worry 24/7, whether I was with him or not. “Out of sight, out of mind” didn’t come into it for me. That left me on the verge of panic every waking second (and there were a lot because I couldn’t sleep at all!).

I know that at the time, I didn’t appreciate how my partner James was going through the same thing with me.

There were several times that I fell down the stairs when James was at work. Thankfully my injuries were no worse than bruises and the odd strained muscle. But that meant he would be trying to hold down a stressful job whilst wondering what mayhem I was getting myself into. Thinking back, now I can identify times where I lacked the insight to see why my behaviour was so difficult to deal with, and I’m certain there’s 1000’s more that I just don’t remember at all.

The short of it is this: We don’t want to be a burden on our loved ones, but the truth is we have become an added strain on their lives. It’s nobodies fault, and I’m not suggesting that survivors can choose to behave differently. I know that many of us struggle to appreciate how the situation is affecting our loved ones because we just don’t have enough cognitive capacity left to see it.

They want to be acknowledged, but we just don’t see their needs or are unable to express it in the way they need.

If you’ve not seen what I mean by not being able to see their needs, or think that can’t apply to you I’ve got a different type of example that might hit the mark. If you’ve ever had a review with your manager that went worse than you were expecting, you’ll know want I’m talking about. I remember when I was trying to make my mark in my early twenties, and I worked hard every day. So, I would be perplexed when in a review, my manager would be able to pick out so many errors which I had thought were minor at the time. And then as they explained the knock-on effects of these “minor” errors, it would slowly dawn on me how important these events actually were. These meetings were horrible, and I would be annoyed at myself for not seeing the consequences first. If I’d been able to acknowledge the problem first, I could have doused the flames, thus reducing the dressing down I got.

Therefore, I understand that it’s hard to recognise something that you can’t see happening. But we know our family and friends are trying. We can admit that it’s not an ideal situation for anyone involved.

Just like it’s heart-warming when someone gives you a present just because “I saw this and thought of you”, random acts to remind those close to you that you appreciate them can go a long way.

Here are some suggestions that could help them feel acknowledged that don’t cost money:

  • Send them an email just saying thank you for all they do. If you want to make it extra fancy, you could send them an ecard and customise it. Smilebox.com lets you do this for free and they have loads of templates that you can use to make it easy.
  • Write a little message on a post-it note and leave it somewhere that they will come across later. The inside of the front door or the bathroom mirror are always a winner. Keep it simple, “I love you” tends to go down well.
  • Get your local radio station to give them a shout out, so everyone knows what a star they really are.
  • Post it on Facebook/Twitter/Instagram or whichever social network you like best, saying why you think so much of them.

Dad had an even simpler solution which was precisely what I needed.

There were times that I didn’t know how to continue when I was doing my best for Dad. I would cry saying to myself “I just can’t do any more than I do, even if it’s not enough.” But I did that only in private, so Dad never saw how close to the edge I was. Then it would be during a conversation with one of his life–long friends, or my sister in America that I would find that I did have the strength to continue… They would tell me how Dad always told them “Without Michelle I don’t know where I would be.” The honesty in that statement from a very proud man who was desperately trying to protect his independence was all I needed to know. The fact that he was telling others as well as me proved he wasn’t just trying to say the right thing.

Love is unconditional, but just like a parent needs to hear their child say thank you and know that their efforts to do the best for their children are recognised, the same goes for those who are trying to support us through a brain injury.

[BLOG POST] The 10 Best Foods To Eat For TBI Recovery

When you have a traumatic brain injury, knowing which foods you should eat and avoid becomes more very important.

Your body reacts to everything you put into your body so you want everything you eat to to have a positive impact on your brain.  Each type of food comes with its particular nutrients and macro-nutrients, some that are beneficial for the brain and others that are bad overall.

In this article, you will discover the 10 best foods to eat for TBI recovery, particularly brain rich foods and others that encourage the healthy regeneration of your brain and boost your general well-being.

What Your Brain Needs

Canva - null (35)

Before you learn the best foods, it’s important to understand the qualities that your brain needs to regenerate. When you suffer a TBI, your brain desperately needs energy and certain vitamins and minerals to help repair it effectively.

Therefore, your brain’s diet should consist of protein-rich foods and foods that are high in favorable vitamins and minerals like magnesium and zinc.

You also want to help protect your brain from further inflammation, free radicals, and you want to boost the communication between brain cells, which is achieved through powerful antioxidants.

And, of course, you want to avoid highly processed foods that generally don’t offer any of these necessary vitamins and minerals.

You’ll also want to avoid sugary drinks, fatty meat cuts such as lamb chops, alcohol, caffeine, and dairy products like cheese and cream. You’ll want to eat some of these very sparingly to get the best improvements.

With that in mind, you can essentially gauge the right foods for you, but here is a list to help get you started.

#1 Fatty Fish

Fish such as salmon, trout, and sardines are great for brain recovery because they are high in omega-3 fatty acids. Did you know that 60% of the brain is made up of fat?

Half of this comprises omega-3, so if fatty fish is the best source of both protein and fat for your brain. But that’s not all – omega-3 also preserves the brain’s plasticity, and since you, the TBI sufferer, needs to virtually rewire the brain, this is crucial.  Another benefit of fish is that it is a great source of creatine, which also helps rebuilding brain cells.

If you are someone who absolutely loathes any fish, then you can find omega-3 in other sources such as dark leafy greens, soybeans, and fish oil supplements.

#2 Meat

According to Psychology Today, “Eating protein raises the levels of another amino acid called tyrosine, which prompts the brain to manufacture norepinephrine and dopamine… A healthy brain produces hundreds of neurotransmitters needed for regular maintenance of the brain and needs proteins to do so.”  Meat is not only nutritious, it is protein dense as well   Red meat, in particular, is an excellent source of zinc, which is another nutrient left heavily depleted after a brain injury.

Be sure not to eat too much red meat, though, as that itself can cause other issues. Incorporating some into your diet is ideal for brain improvement, though.

Other red meat alternatives include soybeans and legumes, such as beans and lentils.

#3 – Blueberries

Blueberries are powerful antioxidants and provide a range of health benefits, all positive for the brain. Some studies have even shown blueberries to help improve memory!

There are also other berries you can include in your diet, such as raspberries and blackberries, that also provide a similar effect.

#4 – Dark Chocolate

Yes, you can include some sweet into the diet with dark chocolate! The darker you can eat, the better. Dark chocolate has very high levels of magnesium and antioxidants, but even so, it should be eaten in moderation.

The more cocoa there is, the better it is for you, so always try and eat the darkest chocolate you can manage – at least 70% cocoa.

#5 – Turmeric

Recently, turmeric has exploded in popularity for its famed health effects. It may look familiar because it is one of the key ingredients in curry powder.

Curcumin, which is the active ingredient in turmeric, can cross the blood-brain barrier,  therefore meaning it can directly enter the brain.

It is a powerful antioxidant and anti-inflammatory compound, and with its ability to enter the brain, it can provide an enormous range of benefits, including increased memory, promotion of brain cells, and reduced depression symptoms.

Turmeric can be purchased in supplement form or as a spice sprinkled on your food.

#6- Nuts

Canva - Walnut

Eating nuts is excellent for your health, and each type of nut comes with its own benefits. But most offer healthy fats, vitamin E, and antioxidants that offer excellent brain-health benefits.

Walnuts, in particular, have omega-3 fatty acids, and almonds have high levels of magnesium, so both of these should be considered.  In addition to ALA omege-3 fatty acid, walnuts are also one of the best sources for melatonin, the sleep regulating hormone.  So if you suffer from insomnia, incorporating walnuts into a balanced diet, and exercise, might benefit you.https://www.youtube.com/embed/tO73SkzQ-C4?version=3&rel=1&fs=1&autohide=2&showsearch=0&showinfo=1&iv_load_policy=1&wmode=transparent

#7 – Oranges

Oranges are packed with vitamin C, and you can get your daily dose with just one medium orange. Did you know that vitamin C is a key factor in preventing mental conditions?

You can help boost your brain’s recovery while also protecting it against age-related mental diseases and conditions, such as Alzheimer’s disease.

Other vitamin C rich foods include kiwi, tomatoes, and guava.

#8- Dark Leafy Greens

“Make sure you eat your greens” – your parents were right. Eating your dark leafy greens is crucial to an optimal diet because they each contain a great source of fiber, folate, and carotenoids.  Most importantly for TBI survivors, however, dark leafy greens are packed with magnesium which can help with TBI related side-effects such as tight muscles, insomnia, and anxiety.

Furthermore, they are rich in vitamins C and K, and the minerals calcium and iron. Many greens provide both an anti-inflammatory and antioxidant effect for your brain.

Dark leafy greens include kale, rocket, collards, bok choy, spinach, and broccoli is also another powerful vegetable for the brain.

#9- Eggs

Eggs are a must-have food for TBI sufferers because they contain a good source of choline. This is a nutrient that creates the neurotransmitter “acetylcholine,” which assists with both mood and memory.

When you have a higher choline intake, you have improved cognitive function. Try having eggs as a main part of your diet to boost your brain’s recovery process.

#10- Avocadoes

Avocadoes are a source of unsaturated fat. Since high blood pressure is linked with cognitive decline – two possible negative side effects of TBI – eating monounsaturated fats may help to reduce blood pressure, thus protecting against cognitive decline.

Other sources of healthy unsaturated fats include walnuts, cashews, and fish.

Herbal remedies also pose well for positive cognitive functioning, such as sage, chamomile, lemon balm, ginseng, and green tea remedies that have shown to lead to sharper thinking, boosted mood, and improved memory.

To Sum it up

It’s important to remember that everyone is different with their own likes and dislikes. Additionally, you could be allergic to one of the foods mentioned, which you would, of course, avoid in that case.

There are also some supplements that might be beneficial for you, such as multivitamins, probiotics, and antioxidant tablets like vitamins C and E.

Take your personal situation into account when incorporating these foods into your diet. Still, you can ultimately expect your brain to healthily improve over the days and weeks of your recovery with these 10 essential foods.

[Abstract] An Analysis of Wrist and Forearm Range of Motion using the Dartfish Motion Analysis System

Abstract

Introduction

Wrist range of motion (ROM) is considered the universal measurement of success for both surgical and non-surgical treatments. A goniometer can be challenging for an individual; to use by themselves, whereas the Dartfish app can analyze and provide immediate feedback to monitor and evaluate patients’ kinematic changes during recovery.

Purpose

of Study: To establish the validity and reliability of the Dartfish app measuring ROM in order for it to be used in clinical applications.

Methods

Twelve healthy participants, ages 18 to 25, with no previous history of wrist injuries were recruited for this study. The ROM measurements collected were flexion/extension, radial/ulnar deviation, and supination/pronation for both goniometer and Dartfish measurements.Goniometer measurements were performed using a plastic universal two-arm goniometer. Dartfish measurements were performed by two observers on an iPad Pro for three trials. Statistical analyses such as t-tests, and the Pearson correlation coefficient, as well as reliability analyses, such as intraclass correlation coefficient (ICC), and Bland-Altman plots were performed.

Results

There was no significant difference between the goniometer and Dartfish ROM measurements except for the ulnar deviation measurement. The concurrent validity showed nearly; perfect correlations between examiners using Dartfish with r-values that ranged from 0.904 to 0.997, and between ADK and the goniometer showed medium, large, and very large correlations since the values ranged from 0.418 to 0.829. The ICC for test-retest reliability had excellent agreement which ranged from 0.993 to 0.999 and the ICC values for inter-observer reliability had good and excellent agreement which ranged from 0.893 to 0.997.

Conclusion

Overall, the results demonstrated that the Dartfish app was a reliable and valid method to measure wrist and forearm ROM. A patient would be able to easily record their own ROM measurements videos and track their progress during their recovery without the need to visit their physician.

[ARTICLE] A reward–punishment feedback control strategy based on energy information for wrist rehabilitation – Full Text

Abstract

Based on evidence from the previous research in rehabilitation robot control strategies, we found that the common feature of the effective control strategies to promote subjects’ engagement is creating a reward–punishment feedback mechanism. This article proposes a reward–punishment feedback control strategy based on energy information. Firstly, an engagement estimated approach based on energy information is developed to evaluate subjects’ performance. Secondly, the estimated result forms a reward–punishment term, which is introduced into a standard model-based adaptive controller. This modified adaptive controller is capable of giving the reward–punishment feedback to subjects according to their engagement. Finally, several experiments are implemented using a wrist rehabilitation robot to evaluate the proposed control strategy with 10 healthy subjects who have not cardiovascular and cerebrovascular diseases. The results of these experiments show that the mean coefficient of determination (R 2) of the data obtained by the proposed approach and the classical approach is 0.7988, which illustrate the reliability of the engagement estimated approach based on energy information. And the results also demonstrate that the proposed controller has great potential to promote patients’ engagement for wrist rehabilitation.

Introduction

Stroke has become one of the major diseases that threaten people’s physical and mental health in the world.1 Loss of control of upper limbs is a common impairment underlying disability after stroke for patients, which seriously affects their daily activities.2 Traditional physical therapy is labor intensive and requires great energy of therapists.3 With the development of robotics, the emergence of rehabilitation robots provides a new way for rehabilitation.4 Rehabilitation robots are able to assist patients to complete training tasks without therapists. In addition, rehabilitation robots are capable of estimating patients’ rehabilitation status accurately through a variety of sensors, which helps therapists to develop a follow-up treatment plan for patients.

Control of rehabilitation robots, however, remains an open-ended research area. Control strategies, which target subjects ranging from the mildly impaired and severely impaired, are the most extensively investigated controller paradigm in the rehabilitation robotics community and have been proved to be the most promising techniques for promoting recovery after stroke.5,6 There is strong evidence that high engagement in rehabilitation training induces neural plasticity.7 Therefore, great attention is paid on investigating how to use robot control strategies to promote patients’ active engagement in robotic therapy.

Assist-as-needed (AAN) control strategy is one of the most popular research topics in the field of rehabilitation robots control strategies and is considered promising to promote patients’ engagement. As the name suggested, AAN control strategy emphasizes that robots only supply as much effort as a patient needs to accomplish training tasks by estimating his/her performance in real time.8 Impedance control first proposed by Hogon was applied in AAN control strategy primitively.9 Representatively, Krebs et al. proposed an AAN controller based on impedance control with MIT-Manus,10,11 which can update impedance parameters according to patients’ performance. In this case of robotic therapy, the robot provides assistance based on specific impedance parameters when the subject is not able to track the desired trajectory and does not provide assistance when the subject is able to track or exceed the desired trajectory so as to allow the subject to move voluntarily. This kind of mechanism encourages subjects to get rid of the limitations of the desired trajectory, which can be regarded as a reward and make them more active. But some subjects showed signs of slack behavior that they rely too much on the robot’s assistance to complete the task without any punishments.12 In other words, giving only rewards without punishments will cause subjects’ slackness in rehabilitation training. Therefore, it is necessary to develop control strategies exhibiting the reward–punishment feedback.

Wolbrecht et al. proposed an adaptive controller including a forgetting term to create the reward–punishment feedback mechanism.13 The adaptive law is made up of an error-based adaptive law and a forgetting law. The standard adaptive law dominates when there is a major tracking error so as to assist the subject to complete the task, while the forgetting law dominates when there is a minor tracking error so as to decay the assistance force to promote the subject’s active engagement, which forms a mechanism that gives a reward feedback to subjects by exhibiting a minor tracking error when they are highly engaged and gives a punishment feedback by exhibiting a major tracking error when they are slack. But the adaptive controller is model-based, it does not perform well when it is applied to wrist or finger rehabilitation because minor modeling deviations affect the wrist or finger much more than the upper limb. The tracking error will not change significantly regardless of the degree of the subject’s engagement.

Another improvement to the AAN control strategy was proposed by Pehilivan et al., who introduced a minimum AAN control strategy, which relied on Kalman filter to estimate subjects’ capability.14,15 According to the estimated results, the controller updates the derivative feedback gain to modify the bounds of allowable error on the desired trajectory, which also reflects the idea of reward–punishment feedback. Subsequently, Kalman filter was replaced by nonlinear disturbance observer, and the electromyography (EMG) sensors were used to estimate the subjects’ engagement.16

To sum up, in order to promote the engagement of subjects, the common feature of the above control strategies is that they can create a reward–punishment feedback mechanism according to the subjects’ current engagement or performance. To the best of our knowledge, previous researchers have not specifically identified this mechanism. More control strategies for rehabilitation robots support this point of view.1725

In this article, we proposed a reward–punishment feedback control strategy to promote subjects’ engagement for wrist rehabilitation. Firstly, we utilize the energy contributed by the subject to estimate his/her engagement. The energy can be obtained by calculating the integral of the torque contributed by the subject against the position. Secondly, an adaptive controller including a reward–punishment term was proposed. Unlike the adaptive controller above,13 the included term is not constant. Instead, it updates based on the estimated results so that the controller can give reward or punishment feedback to subjects by reflecting different tracking error, which is suitable for wrist rehabilitation. Finally, the control strategy was demonstrated through experiments on healthy subjects without cardiovascular and cerebrovascular diseases operating a wrist rehabilitation robot. The contributions of this work include the development of an engagement estimated approach without any extra sensors, which greatly reduces development costs. This work also proposed an improved adaptive controller including a reward–punishment term for wrist rehabilitation, which has great potential to promote subjects’ engagement.

This article is organized as follows. The second section presents an engagement estimated approach based on energy information and a human robot coupled system modeling. The third section proposes an adaptive controller including a reward–punishment term and details the Lyapunov stability analysis. The fourth section introduces the specific implementation methods of three experiments. The fifth section presents and analyzes experimental results. Eventually, the discussion and conclusion are presented in the sixth section.

Engagement estimated based on energy information

We have developed a wrist rehabilitation robot, a three degree-of-freedom (DOF) device, as shown in Figure 1(a). The device is capable of independently actuating all three DOFs of subject’s forearm and wrist. Relatively, the device has three joints: flexion/extension joint, radial/ulnar deviation joint, and pronation/supination joint can all be controlled. Each joint of the device employs both a brushless DC motor with a conveyor belt to drive. Therefore, the control methods of the three joints are similar, and this article only describes the control strategy of the flexion/extension joint.

[BLOG POST] Alcohol Use After a Brain Injury

I’ve never been what I would consider to be a heavy drinker, but I must admit that I have always enjoyed sharing a few drinks with family and friends. With summer on the horizon and day light extending once again in New Zealand, social gatherings will no doubt be occurring more frequently. For some, that translates in an increased likelihood of sharing a drink as well. Although my Weird Wonderful Brain can’t handle social gatherings really well anymore, I still make an effort to join in whenever I can. Apart from the usual brain injury challenges linked to social gatherings, there is another aspect that I need to consider…alcohol or alcohol free? 

It is an accepted custom in our society to have social drinks and a part of me really enjoys getting in on the bandwagon too. However, since encephalitis and brain injury, I have avoided consuming any amount of alcohol. There are a few reasons for this. Firstly, I feel spaced out most of the time so it tends to make things like following a conversation or simply keeping my balance much harder. On top of the heighten cognitive deficits, I have also noticed that on the rare occasions where I have consumed 2-3 drinks (which is still not a huge amount), the resulting physical effects have been pretty drastic. Alcohol seems to trigger my heart rate to increase considerably, I get loads of ectopic heart beats, I can feel extremely nauseous, I sweat profusely, it can trigger massive headaches and my tummy seems to get all tangled up.

I found that the cognitive and physical effects of alcohol post brain injury last long after my last drink and will often carry on throughout the night…stopping Sandman from stealing me away for some very well deserved and necessary sleep. Once you add the lack of sleep on top of a social event and a few drinks, it doesn’t take too long for the brain to spiral out of control.

Effects of alcohol on the brain

That led me into conducting a bit of research about the  “effects of alcohol on the brain”. From past personal experience, most of us are aware that alcohol, even if consumed at a recreational level, can alter our senses, bodily functions and cognitive functioning. Although they are likely to be temporary effects, alcohol can indeed slow our reaction time, alter or thinking and decision making process, trigger a loss of inhibition, induce blurry vision, impair our memory, slur our speech, muck up our balance, coordination and mobility and when consumed in excess, alcohol can even trigger black outs and cause us to be sick. From that list of ways in which a brain is affected by alcohol, I can already identify several cross-overs with how my Weird Wonderful Brain has been affected by the acquired brain injury. Some of those effects are present in spite of me being alcohol free so I was keen to dig further to better understand how an injured brain is likely to be further impacted. 

Effects of alcohol on an injured brain

There are bits and pieces of information out there on brain injury and alcohol use, but to my surprise, there wasn’t a huge amount.  The sources that I found had a theme in common which is, because alcohol affects the central nervous system, people with a brain injury “are likely to experience even greater problems with alertness, memory, problem-solving, and controlling their behaviour and emotions.”[1]

I eventually landed on the MSKTC website which provides a very interesting fact sheet in regards to brain injury and alcohol use.  The following facts [2] were taken directly from their website and were the ones that resonated the most with me:

  • Alcohol slows down or stops brain injury recovery.
  • Not drinking is one way to give the brain the best chance to heal.
  • People’s lives often continue to improve many years after brain injury. Not drinking will increase the chance of improvement.
  • Not drinking can reduce the risk of developing seizures.
  • Drinking alcohol puts survivors at an even higher risk of having a second brain injury. This may be because both brain injury and alcohol can affect coordination and balance.
  • Not drinking can reduce the risk of having another brain injury.
  • Alcohol may affect brain injury survivors more than it did before their injury.
  • Alcohol magnifies some of the cognitive problems caused by brain injury.
  • Not drinking is one way to keep your mental abilities at their best and stay sharp and focused.

There was also very useful information relating to alcohol and depression.  It is proven that people suffering from a brain injury are already at a greater risk of developing a form of mental illness such as depression. Alcohol being a known depressant, it could also cause or worsen symptoms of depression. Therefore, keeping alcohol out of the equation could improve your chances of keeping depression at bay or at least improve your chances of better managing it. 

Post brain injury, you may also need to be aware of how alcohol can affect your current medication. In some cases, it can decrease or stop their effectiveness and in others, it may increase their effectiveness and potential side effects. It is therefore another aspect that needs to be weighted very carefully when making decisions regarding alcohol consumption post brain injury.

During my research, I unfortunately didn’t find much relating to how the consumption of alcohol by a brain injury survivor can impact the heart rate. However, once I took the words brain injury out of the equation,  I found many ways in which alcohol can affect the cardiovascular system e.g: increased heart rate, high blood pressure, weakened heart muscle and irregular heartbeat.[3] Although they aren’t symptoms that I experienced prior to my acquired brain injury, they are very much present now and it demonstrates clearly how my body’s tolerance to alcohol has been impacted…even if consumed at a very low level. I can only assume that the changes in my brain pathways following the encephalitis must have tweaked how the heart electrical system works…making me more prone to temporary arrhythmia perhaps? All I know is that it is an uneasy feeling to experience. I feel my heart pounding and racing in my chest and I can even hear my heart pulsing in my ears as if music was playing in the background…it makes me feel absolutely terrible.

What have I learnt?

From all my readings, it simply seems that a person living with a brain injury is generally more sensitive to alcohol. We generally have less tolerance to alcohol and are at greater risk of experiencing many of its undesirable side effects even if consumed in a much smaller quantity. The payback is also likely to last much longer compared to the average person given all the other factors that brain injury survivors have to take into consideration. Since encephalitis, I’ve had many friends ask questions regarding alcohol consumption and brain injury which I’m always more than happy to answer.  However, I’ve also heard the rare but insensitive comment “Oh aren’t you going to have a drink with us to celebrate such and such person’s birthday”…as if drinking alcohol was a way to show someone that you care, as if it was a must to have a great time. Sometimes I wish that people would remember that part taking in a social event already comes with additional challenges for me and that my brain is foggy enough in the best of times. However, I generally brush those comments off pretty easily…I’m happy to let them hold on to whatever perception they might have. Deep down, I know that the people who truly matter to me don’t care whether I share an alcoholic drink with them or not. The ones who truly care will simply appreciate me being there and that’s good enough for me.

The reality is that post brain injury, there are no level of alcohol consumption considered to be safe and given how my body reacted when I have attempted the occasional 2-3 glasses of wine, I have made the very personal decision to avoid going there. Every now and again I do miss the social aspect of it, I miss the frivolity of the old me. Like most things post encephalitis and brain injury, it is a balancing act I suppose so whenever I chose to have alcohol, I prefer to keep to the one drink. The impact of going over this amount outweighs the positive so I feel like it’s just not worth it for me. I’m not judgmental of those who carry on, I actually used to be one of those person, but I hope that this blog helps those who may be puzzled by my decision to gain a better understanding of the ramifications of alcohol use post brain injury.

[ARTICLE] Functional electrical stimulation therapy for restoration of motor function after spinal cord injury and stroke: a review – Full Text

Abstract

Functional electrical stimulation is a technique to produce functional movements after paralysis. Electrical discharges are applied to a person’s muscles making them contract in a sequence that allows performing tasks such as grasping a key, holding a toothbrush, standing, and walking. The technology was developed in the sixties, during which initial clinical use started, emphasizing its potential as an assistive device. Since then, functional electrical stimulation has evolved into an important therapeutic intervention that clinicians can use to help individuals who have had a stroke or a spinal cord injury regain their ability to stand, walk, reach, and grasp. With an expected growth in the aging population, it is likely that this technology will undergo important changes to increase its efficacy as well as its widespread adoption. We present here a series of functional electrical stimulation systems to illustrate the fundamentals of the technology and its applications. Most of the concepts continue to be in use today by modern day devices. A brief description of the potential future of the technology is presented, including its integration with brain–computer interfaces and wearable (garment) technology.

Background

Losing the ability to move voluntarily can have devastating consequences for the independence and quality of life of a person. Stroke and spinal cord injury (SCI) are two important causes of paralysis which affect thousands of individuals around the world. Extraordinary efforts have been made in an attempt to mitigate the effects of paralysis. In recent years, rehabilitation of voluntary movement has been enriched by the constant integration of new neurophysiological knowledge about the mechanisms behind motor function recovery. One central concept that has improved neurorehabilitation significantly is neuroplasticity, the ability of the central nervous system to reorganize itself during the acquisition, retention, and consolidation of motor skills [1]. In this document, we present one of the interventions that has flourished as a consequence of our increased understanding of the plasticity of the nervous system: functional electrical stimulation therapy or FEST. The document, which is not a systematic review, is intended to describe early work that played an important historical role in the development of this field, while providing a general understanding of the technology and applications that continue to be used today. Readers interested in systematic reviews of functional electrical simulation (FES) are directed to other sources (e.g., [2,3,4]).[…]
