[Effect of amygdalotomy on behavior disorders in epileptics]

Results of psychological testing in 46 epileptics with severe behaviour disturbances treated surgically, by the stereotaxic method (selective exclusion of the dorso medial parts of amygdalae) are reported. After the operation there was a significant improvement of behaviour and seizures of temporal-lobe type were no longer observed. Comparative tests demonstrated a significant reduction of emotional tension, development of ability to behaviour and emotional reactions control, reduction of emotional instability and motor hyperactivity. Aggressiveness in difficult or conflict situations was markedly diminished or eliminated.
