ECT is most often used as a treatment for severe major depression , mania (often in bipolar disorder), and catatonia.

Today, an estimated 1 million people worldwide receive ECT every year,usually in a course of 6–12 treatments administered 2 or 3 times a week.

Transcranial Magnetic Stimulation

Weak electric currents are induced in the tissue by rapidly changing magnetic fields

It can be used for the treatment of depression, schizophrenia, and bipolar disorder

Insulin Shock Therapy

A form of psychiatric treatment in which patients were repeatedly injected with large doses of insulin in order to produce daily comas over several weeks.

It was introduced in 1933 and used extensively in the 1940s and 1950s, mainly to induce remission in schizophrenia.

There were no standard guidelines for treatment; different hospitals and psychiatrists developed their own protocols.

3 Newer Types of Psychosurgery

Capsulotomy

The surgeon inserts probes through the top of the skull and down into the capsule, which is deep in the brain near the thalamus.

By leading the tips of the probes, the doctor can burn away small portions of tissue, each about the size of a raisin. Used in OCD

Cingulotomy

Probes are inserted through the skull into the cingulum, a bundle of connections located near the capsule.

The probes' tips are heeded and tissue is burned, as the capsulotomy. Used with Chronic Pain, OCD or depression

Deep brain stimulation

The surgeon inserts a “brain pacemaker” through the skull and into the capsule no tissue is destroyed. Helps control tremors ie: Parkinson’s. Has also been helpful in treating chronic pain
