ECT (Electro Convulsive Therapy) For Mental Health?
Commonly used to treat mental disorders such as severe depression, schizophrenia, bipolar disorder and catatonia (characterized by lack of movement, fast or strange movements, lack of speech, and other symptoms), Electro Convulsive Therapy (ECT) can be an effective and safe procedure. It is practiced worldwide as well as in the South African private and public sector. “ECT is usually considered as a treatment options where other treatment options like medication have failed, or where rapid results are crucial e.g. suicide risk. ECT also tends to work better in older people,” says Dr P.J. Malherbe, a psychiatrist at Akeso Clinic in Arcadia.
Entailing a small electric current being applied to the scalp, ECT is used to induce a brief convulsion in the brain, he explains. Some Akeso clinics have ECT licenses and facilities, and the treatment is performed by a psychiatrist along with an anaesthetist.”The procedure involves being taken to an ECT theatre, where an anaesthetist will administer in exactly the same way as it would be done for any minor surgical procedure. Once the patient is under anaesthesia, two electrodes are held to the scalp – no cutting or shaving of hair is necessary – through which a small electric current is applied by an ECT machine. “The duration, nature and strength of the current is carefully controlled and determined by the psychiatrist. The charge strength is measured in millicoulombs and is therefore extremely small. The resulting convulsion is measured with the use of a monitor attached to the patient, because the patient’s muscles are relaxed and visible features of convulsing are barely seen.

“The brief typically lasts 15 – 40 seconds and the whole procedure is completed within about 5 minutes after which the patient spontaneously regains consciousness. Six of these treatments are generally necessary over a two week period for sufficient improvement in symptoms, depending on each case. In most cases it is done while a patient is admitted to hospital, but it may in certain cases be done as a day procedure,” according to Dr Malherbe.
“Ever since the 1930’s seizures have been used to treat psychiatric ailments where it was observed that patients with schizophrenia would improve spontaneously after experiencing an epileptic fit or convulsion. Initially medication like insulin were used to induce a seizure. This practice was abandoned due to the risks and side effects, and instead an electric current was used to produce a seizure – with less risk,” Dr Malherbe points out. However, it was not until the 1950’s with advances in anaestesia, that ECT was widely practiced. A seizure could now be induced while a patient was under general anaesthesia, making the procedure much more tolerable and safe, according to Dr Malherbe. “ECT can also be employed where medications are not advisable, for example a pregnant patient. It is safe for use in pregnancy in comparison to other medicines. The procedure is undoubtedly effective with more than 70% of people with depression reponding favorably, making it more effective than other treatment options. The benefit is also rapid, with improvement sometimes seen within days, as opposed to medications that may take longer to start working.”
Risks, side effects
According to ECT information supplied by Mayo Clinic, ECT is generally safe, but there may be risks and side effects. WHile most patients who responded to ECT questions by the website is healthtalk.org, confirmed that they experienced side-effects, others had very little, even none.
“Most people we spoke to had some side effects from the treatment. Side effects ranged from patient to patient. “However, a few of the people we interviewed experienced little if any side effects of having ECT, and some pointed out the side effects of taking medication could be worse.” Aftercare It is important to continue medication for maintenance of improvement after the treatment. Periodic follow-up with a psychiatrist or medical practitioner is therefore necessary.
Unfortunately the treatment remains stigmatized because of various misperceptions and archaic ideas,” says Dr Malherbe.
“Most people we spoke to had some side effects from the treatment. Side effects ranged from patient to patient. However, a few of the people we interviewed experienced little if any side effects of having ECT, and some pointed out the side effects of taking medication could be worse.” One respondent even said that he experienced no bad effects from ECT at all, and it was like having a cataract operation. As with most medical procedures, side effects are possible. In ECT, side effects can include headache, forgetfulness and muscle ache. Possible risks and side effects are always discussed with the patient prior to the procedure and informed consent obtained.
