Abstract
Increased Impulsivity Associated With Severity of Suicide Attempt History in Patients With Bipolar Disorder
Swann A C~~Dougherty D M~~et al
In bipolar disorder subjects with either a definite history of attempted suicide or no such history, impulsivity was assessed with a questionnaire & behavioural laboratory performance measures. Subjects with a history of suicide attempts had more impulsive errors on the immediate memory task & had shorter response latencies, especially for impulsive responses. Results suggest that a history of severe suicidal behaviour in patients with bipolar disorder is associated with impulsivity, manifested as a tendency toward rapid, unplanned responses. (54 refs.)
