Sažetak
Objective: We wanted to assess possible alterations in brain activation in PTSD patients with severe hyperarousal symptoms and impulsive aggressiveness. Method: 25 Croatian War (1991-1995) veterans with combat-related PTSD with severe hyperarousal symptoms and impulsive aggressiveness were assessed for possible alterations in cerebral blood flow in single photon emission computed tomography brain scans. Results: Increased regional cerebral blood flow in projection area of nucleus accumbens was found in 13 of 25 subjects, and for all in the dominant brain hemisphere. Discussion: We believe that at least some of PTSD symptoms, and especially the impulsive aggression, can be associated with increased regional cerebral blood flow in the projection area of nucleus accumbens.
