Abstract
- This research was performed to investigate whether or not the psychobiology of posttraumatic stress disorder is related to dopamine systems. Plasma homovanillic acid levels were measured in 16 male patients with posttraumatic stress disorder and in 16 nonpsychiatric normal males. Posttraumatic stress disorder was diagnosed using the DSM-IV. Plasma homovanillic acid levels were significantly higher in patients with posttraumatic stress disorder than in normal control subjects(p<0.05). The findings of this study suggest that hyperactivity of dopamine systems may be related to the psychobiology of posttraumatic stress disorder.
