    How can trauma affect the brain?

    The human brain is characterized by surprising plasticity. Even when one part is injured, the functions of the damaged neurons can be taken over by other cells. This is because neural tissue has a remarkable ability to form new connections to reorganize, adapt, change, and self-repair the entire organ.

    What is expected in recovering from a traumatic brain injury?

    Often, the fastest improvement happens in the first six months after injury. During this time, the person with the injury will likely move and think better. As time goes by, the speed of improvement will slow down, but the person may continue to gain more function for years after the injury.
