PTSD is a mental health disorder that some people develop in response to witnessing or experiencing a traumatic event. It is characterized by subsequent marked emotional and behavioral reactions, which cause distress and interfere with daily functioning. Notably, it is not uncommon for individuals with PTSD to experience alterations in cognitive functioning, including difficulties with concentration, executive functioning, and memory. Neuropsychological evaluation of PTSD can be extremely valuable to clients and treating providers in terms of clarifying what pattern(s) of neural dysfunction might be present to help inform possible directions related to ongoing treatment, behavioral interventions, and/or vocational (or educational) planning.
