Electroconvulsive therapy (ECT) is a procedure in which a brief
application of electric current to the brain, through the scalp, induces a
seizure. It is typically used to treat a patient who is suffering from severe
Why is ECT used?
ECT is one of the fastest ways to relieve symptoms in
severely depressed or suicidal patients, in patients who suffer from mania, and
in other mental illnesses. ECT is generally used as a later treatment option
when severe depression is unresponsive to other forms of therapy, or when the
patient is so ill that his or her life is in danger. It also is used when these
patients pose a severe threat to themselves or others, and it is dangerous to
wait until medications take effect.
How is ECT performed?
Prior to ECT treatment, a patient is put to sleep using
general anesthesia, and a muscle relaxant is given. ECT causes the patient to
have a seizure. Electrodes are placed on the patient’s scalp and a finely
controlled electric current is applied, which causes a brief seizure in the
brain. Because the muscles are relaxed, the seizure will usually be limited to
slight movement of the hands and feet.
Patients are carefully monitored during the treatment. The
patient awakens minutes later, does not remember the treatment or events
surrounding the treatment, and may feel confused. This confusion typically lasts
for only a short period of time. ECT is given up to three times a week for 2 to 4 weeks.
A course of ECT is usually followed by psychotherapy and medicine under a psychiatrist's care.
ECT: A controversial treatment
ECT remains the most controversial treatment for psychiatric
illness, although it has been used since the 1940s and 1950s. Many of the risks
and side effects have been related to the misuse of equipment, incorrect
administration, and improperly trained staff. There also is a misconception that
ECT is used as a "quick fix" instead of long-term therapy or hospitalization.
Unfavorable news reports and media coverage have added to the controversy of
this treatment. In fact, ECT is safe and among the most effective treatments
available for depression.
Making an informed decision about ECT
Before ECT is considered, you should discuss all available
treatment options for your condition with your doctor. If ECT is recommended,
you should receive a complete medical examination including a history, physical,
neurological exam, ECG (heart test), and lab tests. Your medication history
should be carefully evaluated and monitored.
If you are considering ECT as a treatment option, be advised
that it may provide temporary improvement but has a high relapse rate. Many
doctors advocate follow-up treatment that includes medicine or ECT given at less
regular intervals, called "maintenance ECT." Short-term memory loss is the major
side effect, although this usually goes away 1 to 2 weeks after treatment.
You should be educated and informed about ECT and any treatment
prior to receiving it. Ask for educational literature, videos, and an honest
discussion with your doctor about the potential benefits and side effects.
