Post-traumatic Stress Disorder after Severe Traumatic Brain Injury: A Systematic Review.

Only a few studies in the literature have addressed the present topic; therefore, the prevalence of post-traumatic stress disorder in patients with severe TBI still needs to be further investigated. In particular, future studies should be conducted only in severe TBI populations, considering their premorbid personality characteristics and their reactivity alteration. They should also obtain an accurate and appropriate assessment of post-traumatic stress disorder with clinical interviews as well as clarifying the role of post-traumatic amnesia in this population by incorporating control groups of patients.
