Violence and temporal lobe lesion: head CT and MRI data
JM Tonkonogy
Department of Psychiatry, University of Massachusetts Medical Center, Worcester 01655.
Head computed tomography and magnetic resonance imaging scanning were done
in 23 patients with organic mental syndromes. Violent behavior was observed
in 14 patients. A nonviolent group consisted of nine patients. Five cases
of local lesion in the anterior-inferior temporal lobe were revealed in the
violent group. It is suggested that the release of programs for violent
behavior may result from the unilateral destruction of amygdaloid nuclei or
adjacent structures coupled with the paroxysmal stimulation of preserved
limbic structures by the mechanisms of kindling.
