A brief summary of current research.
Whelan-Goodinson, R, Ponsford, J, Johnston, L and Grant, F (2009). Journal of Head Trauma Rehabilitation, Vol. 24(5), pp 324-332.
This research found that more than 60 percent of people with a brain injury had psychiatric disorders up to 5.5 years post-injury. Many of these were new cases of depression and anxiety and were not present prior to injury. The authors suggest that individuals with TBI should be screened for psychiatric disorders several times post-injury regardless of pre-injury psychiatric status, so that appropriate help can be offered.
