Understanding how brain injuries may lead to memory loss and dementia

Researchers want to understand whether people who have experienced one or more mild or moderate brain injuries are at risk for developing dementia or memory problems later in life. This study will evaluate your memory, brain wave activity, brain structure, and specific proteins in your blood and spinal fluid that may be connected to brain injury and dementia. By comparing people with brain injuries, people with mild memory problems, and healthy people without brain injuries, scientists hope to figure out who is most likely to develop dementia and when it might occur.

Many people have survived brain injuries, but doctors don't yet know who will go on to develop memory loss or dementia—or when that might happen. This research could help identify which people need closer monitoring and earlier treatment to prevent or slow down cognitive decline.
