Post-traumatic stress disorder (traumatic war neurosis) and concurrent psychiatric illness among Australian Vietnam veterans. A controlled study.

Depression, anxiety, irritability with unpredictable explosions of aggressive behaviour, impulsivity, suicidal actions and substance abuse have been repeatedly observed among ex-servicemen from World War II in psychiatric treatment settings. In the most recent American Psychiatric Association classification of mental disorders the category of Post Traumatic Stress Disorder (PTSD) was introduced, replacing the earlier Traumatic War Neurosis and the above cluster of symptoms were included as associated features of this disorder. Two recent uncontrolled studies on U.S. Vietnam veterans receiving psychiatric care supported the linkage of PTSD with these abnormalities. However, the present controlled study found these associated features occurred with equal frequencies among one group of psychiatrically hospitalised Australian Vietnam veterans with PTSD and another group not so afflicted. Reservations, then, should be harboured about ascribing all the presented psychopathology and behavioural abnormalities of ex-servicemen to the stress of their war service.
