This form of treatment may take a few weeks. For many people, attending 10-15 sessions leads to significant improvement.
  • ŸECT. Electroconvulsive therapy or ECT is a medical treatment commonly used in bipolar disorder or severe major depression that does not responded to other forms of treatment. It involves the application of brief electrical stimulation to the brain under anesthesia.
