Abstract
Traumatic brain injury ( TBI) neuropsychiatric sequelae are a significant cause of morbidity in TBI victims. Among the recognized sequelae are anxiety, obsessions, compulsions and obsessive-compulsive disorder (OCD). This review addresses the emergence of OCD and OCD symptoms after TBI with an emphasis on neural circuits that underlie OCD symptom expression that may be affected by the injury. Current studies suggest that post-TBI emergent psychopathology, including OCD, is influenced by underlying sub-clinical diathesis, brain injury lesions sites, environmental stressors and the rehabilitation process. Pre-morbid status can be obtained by structured psychiatric interviews, and TBI brain lesions can be defined with advanced neuroimaging techniques. This information along with the management of family and environmental stressors and the enhanced clinical identification of symptoms of anxiety and OCD can be used in the rehabilitation process to improve prognosis after TBI.
