Everything takes effort. The energy for the whole day is often consumed completely within two hours. There are many brain injury victims who have insomnia ón top of this all. Another group of brain injury survivors have an increased need for sleep. But the similarity is FATIGUE.
Mental fatigue is different from physical fatigue. We can all get an idea when talking about physical fatigue. Being tired after an exercise, after a brisk walk, after strenuous physical labor, after housework and so on.
Mental fatigue comes in thinking processes, learning and information processing, watching television extensively, doing computer actvities, but also solving problems, interpreting the behavior of other people and thinking logically.
A healthy person can also be mentally tired of all such functions if it is intense and long enough. Healthy people can also come to a point that they become annoyed when the “energy” is low, and especially if that mental activity was filled with noise. It seems like you cannot endure radio or TV, or something like that, anymore.
For brain injury victims that is many times worse. The mental energy has already been exhausted after a short time. They use more parts of the brain, because the dead area must be passed by, in the communication between braincells.
Neuro-fatigue is one of the most debilitating consequences of a brain injury, as it influences everything the injured person does, both physically and mentally. A person’s emotions can also become raw when they are tired.
At the beginning, the ABI survivor is likely to find out that he or she will be tired easily after any activity, even chatting to friends or watching television, but particularly after tasks that require concentration or physical effort. This can be very depressing, particularly if the individual is aware of this change.
They will often try to push themselves to complete a task in the belief that they might overcome their fatigue. This is seldom the right thing to do as it can lead to increased fatigue in long-term. It takes time to build up energy. Taking rest periods both in between activities and when feeling tired is essential.
