Summary

This study tests two different therapies to help people with ongoing memory problems after a concussion. One is traditional cognitive rehabilitation, and the other is a new cognitive-behavioral therapy (CBT) approach. Researchers want to see which one works better for improving how people feel about their memory. The study will include 184 adults aged 18 to 59 who had a concussion 6 to 36 months ago.
