Electroshock therapy and brain damage: The acute organic brain syndrome as treatment

The effectiveness of electroconvulsive therapy: A literature review

Aim – To review the literature on the efficacy of electroconvulsive therapy [ECT], with a particular focus on depression, its primary target group. Methods – PsycINFO, Medline, previous reviews and meta-analyses were searched in an attempt to identify all studies comparing ECT with simulated-ECT [SECT]. Results – These placebo controlled studies show minimal support for effectiveness with either depression or ‘schizophrenia’ during the course of treatment (i.e. only for some patients, on some measures, sometimes perceived only by psychiatrists but not by other raters), and no evidence, for either diagnostic group, of any benefits beyond the treatment period. There are no placebo-controlled studies evaluating the hypothesis that ECT prevents suicide, and no robust evidence from other kinds of studies to support the hypothesis. Conclusions – Given the strong evidence (summarised here) of persistent and, for some, permanent brain dysfunction, primarily evidenced in the form of retrograde and anterograde amnesia, and the evidence of a slight but significant increased risk of death, the cost-benefit analysis for ECT is so poor that its use cannot be scientifically justified.

Effects of an education training program on attitudes to electroconvulsive therapy

Widespread negative attitudes toward electroconvulsive therapy (ECT) are present in the general public and among heath care professionals. However, there is evidence to suggest that clinical experience and knowledge of ECT positively improve attitudes toward this treatment. The purpose of this study was to evaluate the effects of an ECT education training program on attitudes toward ECT. Participants were 73 student nurses (91.8% women) and 21 care aid students (81.0% women) undertaking a 6-week rotation in psychiatry at a large provincial psychiatric hospital in British Columbia, Canada. The ECT education training program consisted of a brief lecture, viewing of an educational videotape, familiarization with the ECT equipment, and observation of an ECT treatment. Participants completed a short questionnaire pretraining and posttraining program. Attitudes toward ECT did not substantially differ between the 2 groups. For the entire sample, only 8.5% reported that they were well informed about ECT before the training session. More favorable attitudes were reported upon completion of the ECT education program compared with attitudes reported before training. These findings suggest that attitudes toward ECT increase favorably when individuals are provided with training and experience.
