This study is no longer recruiting. The population recruited were individuals who have served in the Iraq or Afghanistan wars and were experiencing any difficulties related to a mild or moderate traumatic brain injury (TBI) sustained during deployment.
The purpose of this study was to learn about the effects that TBI has on extinction learning- a type of learning that has been identified as important in the development of anxiety disorders. We also wanted to better understand the effects that TBI has on functioning in general, and on mood and anxiety symptoms. This was done for the larger purpose of helping us to learn about the ways that our minds process stress.
The tests and procedures associated with this study took each participant a total of 1-2 days to complete. Participants completed an interview with one of the study clinicians, a neuropsychological assessment and a scanning procedure using x-ray and fMRI machines. All participants also completed a series of self-report measures.
