Akathisia and violence

Abstract

Akathisia is a common side effect of neuroleptic drugs that may present with behavioral disturbances. There have been preliminary reports on the association between violence and akathisia. We report the first observational study of this relationship. Patients studied were from a special unit for violent patients. A closed-circuit television camera was installed in each of the corners in its dayroom. Incidents of assault plus the 5 minutes preceding each assault were recorded on videotape. Participants and bystanders were rated for the motor component of akathisia. For each of nine incidents, we compared the akathisia scores for participants and for bystanders. Both victims and assailants were akathisic before about half of all incidents; bystanders rarely were. The classification of the movements we rated and the implications for further studies are discussed.
