Psychomotor retardation and agitation in depression. Relationship to age, sex, and response to treatment.

Patients with primary affective disorder who had either psychomotor agitation alone or psychomotor retardation alone were studied. Compared to psychomotor retardation, psychomotor agitation appears to be seen more frequently in women, older patients, and individuals who have a late onset to their illness. In addition, those with agitation alone appeared to have a better and faster response to electroconvulsive therapy.
