Abstract

Aggressiveness is part of the behavioural manifestations associated with some mental disorders; it is a symptom that is difficult to manage and is often resistant to pharmacological measures. Surgery for behavioural disorders emerges as a therapeutic alternative. This procedure consists in performing interventions on different structures of the limbic system in order to correct the alteration of the circuit involved in producing the symptoms. To describe the clinical outcomes of a posterior hypothalamotomy with gamma knife to control aggressiveness in 20 patients resistant to treatment, who underwent surgery at the Imbanaco Medical Centre between 2013 and 2018. The severity of the aggressiveness was quantified using the Overt Aggression Scale (OAS) and the Clinical Global Impression Scale (CGI-SI), and its functional impact is evaluated using the Global Assessment of Functioning scale (GAF). Control over aggressiveness was observed in all patients treated by posterior hypothalamotomy with gamma knife, evidenced by a decrease in the scores on the OAS and CGI-SI and an improvement in the GAF. Posterior hypothalamotomy gives rise to few complications, is a safe procedure and offers good results, suggesting that it could be a good ...Continue Reading
