Electroconvulsive Therapy (ECT) is another treatment option that may be particularly useful for individuals whose depression is severe or life threatening, or who cannot take antidepressant medication.
(ECT) can be a very effective and safe treatment for depression. ECT uses electric currents to cause a seizure in patients. This current produces many changes in the chemistry and functioning of the brain. Although a large amount of research has been carried out, the exact mechanism of action of ECT remains elusive. ECT doctors claim it may "jumpstart the brain", helping boost neurotransmission. The brain changes help the patient to fight depression.
Today, ECT is most often recommended for use as a treatment for severe depression that has not responded to other treatment, and is also used in the treatment of mania and catatonia.
