Current opinion suggests that it is feasible to consider self-injurious behavior in various conditions. The behavior may have a common organic component, and there may be an underlying biochemical explanation, such as dysregulation of dopaminergic activity and dopamine-receptor sensitivity or alterations of serotonergic function. Simeon and colleagues, in their recent investigation of self-mutilation in personality disorders, demonstrated the contribution of severe character pathology, aggression, impulsivity, anxiety, and anger to self-mutilation. Although Tuke's Dictionary of Psychological Medicine stated that self-mutilation was encountered "not infrequently" by the "alienist" doctor "both within and without the asylum," it seems likely that such behavior was observed chiefly in psychotic or mentally retarded subjects. This case suggests that normal individuals under alcohol intoxication are no exception.
