        • A electrode is place above the temple on the non dominant side of the brain
        • The patient is unconscious before the electric shocks were given
        • A small current is passed through the brain for half a second causing a seizure lasting a minute
        • ECT is usually given 3 times a week with the patient requiring between 3 and 15 treatments
      • Why does it work?
        • Abrams (1997) has conducted a study lasting for 50 years however we are no closer to understanding how it works
        • ECT alters the way the parts of the brain communite
        • There are disagreements to how it exact effects work
    • Evaluation
      • Drug treatments
        • Research evidence shows that chemo work
          • After a year relapse rates were 55%
          • 25% with chlorpromazine relapped
          • 2%-23% relapsed when taking chlorpromazi and family intervention
        • Placebo effect
          • Kirsch (2002) found that people who took a placebo fared just as well and those who took the real drug
      • ECT can save lives
        • It works particularly well for people who suffer from depression
