- The Center for Neuroscience and Regenerative Medicine is working to improve physicians' understanding of brain injury. More information is needed on traumatic brain injury (TBI), especially how well a person recovers from TBI and how the brain changes over time in people with TBI. To conduct this research, the center is sponsoring a number of research studies on TBI and is interested in evaluating individuals with TBI or post-concussive syndrome to determine if they might be eligible for future studies.


- To develop a pool of individuals with traumatic brain injury and post-concussive syndrome for future research studies.


- Individuals at least 18 years of age who have symptoms of or have been diagnosed with traumatic brain injury or post-concussive syndrome and are willing to participate in future studies.


- Participants will be screened with an initial telephone interview, and will be asked to come to the National Institutes of Health for an in-person screening visit.

- At the screening visit, participants will provide a medical history, have a physical examination and complete a study questionnaire on their TBI and its symptoms, including how the injury occurred, when it occurred, and any previous brain-related injuries.

-Subjects may also return for a second visit at the NIH CC if eligible.

-Each visit may involve blood samples, an MRI scan, and a series of tests to evaluate brain function.

- Participants will also provide contact information to enable researchers to contact them for future studies.
