Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Aggressiveness has a high prevalence in the psychiatry population and is of major concern. Though pharmacological treatments are effective for most patients, there is a portion that doesn't respond properly and is considered medically refractory. For them, surgical procedures (i.e. stereotactic lesions) have been performed as an attempt to reintegrate patient into society. The amygdala is a main structure in the control of aggressive behavior and amygdala lesion could improve behavior without neurological or other behavioral impairment. In this study, it will evaluate the functional results of the bilateral amygdala lesion of aggressive refractory patients through neuroimaging, clinical assessment and blood hormonal levels. To better understand the neurobiology of aggression, aggressive patients that are not refractory will also be studied through neuroimaging and hormonal levels.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Aggressive refractory patient

A pre defined group of individuals will be included in the study. This group is considered aggressive refractory patient and will be submitted to the bilateral amygdalotomy surgery.

Aggressive behavior

Intervention Type BEHAVIORAL

Aggressive Behavior Scale, Quality of Life (SF-36) and Agitated Behavior Scale, measurement of thyroid-stimulating hormone (TSH), T4, T3, Cortisol, Luteinizing Hormone (LH), Estradiol, Prolactin, Progesterone, testosterone, and sex hormone-binding globulin (SHBG) and Resonance Magnetic Imaging.
