Brain damage is more or less permanent. The neurons and neural structures that are destroyed when the brain is damaged for the most part do not regrow. Acquired Brain Injury is a form of brain damage caused by a number of different events from a violent blow to the head (Traumatic Brain Injury, TBI), to gunshot wounds, to tumors and strokes. There are many causes of this including car accidents, warfare, violent disputes, cancer, etc.. Regardless of the cause, the brain is damaged, and the areas that are destroyed are permanently lost.
But, we know that people can recover to some extent from brain injury. How is it possible that recovery can occur when there is no replacement of the damaged tissue? There appears to be a number of strategies that are employed by the brain to assist in recovery. Other areas of the brain can take over some of the function, other behavioral strategies can be employed to accomplish the task, and non-injured areas of the brain can adapt and change to compensate for the lost function.
In today’s article “Mindfulness-Based Stress Reduction (MBSR) Delivered Live on the Internet to Individuals Suffering from Mental Fatigue After an Acquired Brain Injury” https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1016815115009081/?type=1&theater
MBSR is shown to assist in recovery from a particularly troublesome symptom of brain injury, long-lasting mental fatigue. For brain injury victims engaging in mental activities takes tremendous energy and the individual tires (fatigues) quickly. We can theorize that this fatigue comes from having to employ less efficient alternative methods to perform mental tasks that take more energy.
How does MBSR help? It can actually change the brain and make it more efficient in processing mental tasks. It has been shown that mindfulness training can increase the size and connectivity of areas of the brain responsible for focused attention while decreasing the size and connectivity of areas responsible for mind wandering and attentional lapses. By limiting intrusive thoughts, mindfulness improves attentional ability and even memory function.
MBSR can also decrease the emotional reactions of frustration and anger that can occur as a result of struggling to perform a mental task. This can remove an interfering and fatiguing consequence of the disability produced by brain injury. This in turn reduces the energy expended to accomplish the task.
So, mindfulness training can assist the brain injury sufferer by restructuring the uninjured brain tissue to allow for better focused attention and also by reducing emotional reactions to the difficulties. This allows the victim to better engage in mental activities. In essence, it doesn’t heal the damaged tissue, rather it makes the rest of the brain better able to carry out the task.
