[Aggressiveness and residual schizophrenia].

The authors study aggression behaviour in a sample of 20 patients with residual schizophrenia, using the Instrument I for the measure of aggression, developed by professors Ledesma, Rodrigues and Izquierdo. A pattern of aggression has been found among residual patients characterized by a decrease of global aggressiveness and hetero-aggressiveness, compared with a control group. It has also been found a low psychomotive potential and small psychomotive aptitude reactivity. We are of the opinion that the aggressiveness pattern among residual schizophrenia is due to a defect personality, with an organic cerebral base.
