Long-Term Effects of Brain Injury

Dr. Perl emphasizes the importance of understanding impacts of single traumatic brain injuries as well as of CTE.

Although there’s been a great deal of interest and concern about repeated traumatic brain injuries, the long-term effects of single traumatic brain injury is a significant problem as well, okay? It may be different than CTE, but it’s a significant unsolved problem as well. According to the Centers for Disease Control, there are 5.3 million Americans living with long-term disability related to traumatic brain injury. That’s a large number. That’s almost equal to the number of individuals living with Alzheimer’s disease. And yet we’re not really studying this and we really don’t understand the nature of those disabilities. So I think that it’s not just the repeated TBI, it’s the single TBI. It’s the automobile accident, it’s the fall out of a tree, it’s the single TBI as well that should be of concern and can have lasting effects. And that is another area in which there are many gaps in our knowledge.
