Document Summary

Involves administration of general anesthetic and muscle relaxation to prevent convulsions. Causes less memory disruption than earlier versions. Ama concluded that ect methods among most positive treatment effects; reduces suicidal thoughts. Vagus nerve stimulation: stimulates neck nerve that sends signal to limbic system; increases available serotonin by increasing firing rate of some neurons. Deep brain stimulation: manipulates depressed brain via pacemaker; stimulates inhibition activity related to negative emotions and thoughts. Repetitive transcranial magnetic stimulation (rtms): sends magnetic energy to brain surface through coiled wire held close to brain; fewer side effects; modest effectiveness. Involves surgery that removes or destroys brain tissue in an effort to change behavior. Psychosurgical procedure once used to calm uncontrollably emotional or violent patients. Procedure cut the nerves connecting the frontal lobes to the emotion-controlling centers of the inner brain (moniz) Today, less invasive techniques used; mri-guided surgery in severe disorders. Human brains and bodies were designed for physical activity and social engagement.
