ECT proves to be effective in treatment for depression.

ECT, popularly known as electro-shock, is today especially used in treatment of severe endogenous depressions, where it has proven to be effective. Treatment with ECT cuts short the course of the condition in 90-95% of cases. Treatment with drugs works only for about 60-70% of patients, and then only after 2-4 weeks, whereas ECT has an immediate effect.

Following treatment with ECT about 50% of patients will have a relapse. This is a problem especially for those who suffer from antidepressant intolerance.

General anaesthesia.

The earliest treatments that were provided were categorized as so-called dry shock. This referred to that fact that patients were not anesthetized, nor given oxygen or muscle relaxant medicine. Today's electro-shock is administered under general anaesthesia, and prior to the treatment the patient receives a muscle relaxing drug (curare).

At first ECT seems a quite violent treatment. But a study of patients after they have received ECT treatment shows that many felt that it was no worse than going to the dentist.

How the treatment is implemented.

Before administering ECT, the patient undergoes several physical examinations to minimize any risk in relation to anaesthesia. ECT usually consists of 10-20 treatments which can be provided to both inpatients and outpatients. As in surgery, the patient should not eat or drink for a few hours prior to treatment.

Before the treatment starts, anesthesia is provided through an intravenous drip which makes the patient fall sleep and the body’s muscles relax. Once anesthesia is fully working electro-shock is provided through electrodes on the patients head.

The electrical stimulation produces changes in the brain waves. These changes induce epileptic seizures. It is thought that the seizures bring about the patients’ improved condition.

After approximately 30 minutes the patient awakes and, although he may at first be somewhat confused, he is usually immediately well enough to eat and can go home if he is an outpatient

For some it is the right treatment

Bente Djørup, President of the National Association for Mental Health called “SIND”:

Side effects

The most frequently seen side effects from electro-shock therapy are amnesia and cognitive difficulties. The side effects usually wear off after a couple of months. By using one-sided stimulation, in recent years it has been possible to reduce memory problems, but this form of the therapy requires repeated treatments.
So far there is no evidence that ECT can cause brain damage.

The National Association for Mental Health are regularly approached by patients and their families, describing a wide range of side effects that differ from those mentioned above.
SIND also receives inquiries from patients and relatives who say that they have not received the necessary information before being treated and some haven’t had any information at all.

All kinds of medications are toxic

Electroconvulsive therapy 1938

ECT, also called Electroshock Therapy or Electro Stimulation, is short for Electric Convulsive Therapy. ECT developed on the basis of Lazlo Medunas’ experiments with electrically induced seizures on the basis of studies from the 1930s of glia tissue in epileptic patients and patients with schizophrenia. The method was further developed by the Italians Cerletti and Bini and from its outset Electroconvulsive Therapy gained widespread use all over Europe due to the proven efficiency of this form of treatment.

How many people receive Electroconvulsive Therapy

In Denmark, in 1999, approximately 1700 patients were treated with Convulsive Therapy. This corresponds to approximately 16.000 treatments per year or about 44 treatments per day. In comparison with other countries, several studies over the last 20 years show that ECT is used more frequently in Denmark.

On an average, 5% of all hospitalized mentally ill patients in Denmark received ECT in 1999.
