Amygdalotomy

Abstract

The results of a multi-disciplinary research project into the management and assessment of patients with epilepsy and behaviour disturbances are reported in eighteen patients who have undergone amygdalotomy over the past 5 years. The psychological and neurosurgical assessments are detailed and the effects of stimulation and coagulation of the amygdala nucleus are described in six patients. It is concluded that certain cases benefit by amygdalotomy, but that changes are not limited to a decrease in abnormal aggressive behaviour but also lead to a decrease in other areas of maladaptive behaviour. The aim of the operation is to enable the patient to respond more appropriately in a range of situations which in turn would lead to an increase in general effectiveness.
