Clinical characteristics of female alcoholics with low platelet monoamine oxidase activity.
The aim of the present study was to see if female alcoholics had low platelet MAO activity and whether there was a correlation between low MAO activity in female alcoholics and specific clinical characteristics often observed in type II male alcoholics. In earlier studies, male alcoholics have been subdivided into type I and type II alcoholics. Type II alcoholics were characterized by early onset, a high frequency of depression and alcoholism in first degree relatives, a high frequency of drug abuse and social complications, sensation seeking behavior, extraversion, impulsive sensation seeking psychopathy, and low platelet MAO activity. In the present series it was demonstrated that the female alcoholics had significantly lower platelet MAO activities than the female healthy volunteers. The subgroup of female alcoholics with low platelet MAO activity, however, did not differ from female alcoholics with normal platelet MAO activity in the same way as male alcoholics with low platelet MAO activity have been shown to differ from male alcoholics with normal platelet activity. They did not have early onset, higher frequency of depression or alcoholism in their first degree relatives, nor more social complications than the female alcoholics with normal platelet MAO activity. Furthermore, they did not differ from the female alcoholics with normal platelet MAO activity in any personality trait covered by the Karolinska Scales of Personality (KSP).
