Informed consent is provided by the patient or by an individual designated under state law (usually a family member) for patients who are incapable of informed consent. All consent procedures should follow applicable state regulations (which vary considerably). Consent is an ongoing process, which can be revoked at any time. Although the consent form covers the entire series of ECT treatments (except in certain states), it is recommended that reconsent be obtained if an index series is unusually prolonged. Because C/M ECT differs in a number of ways from an index course of treatments, it is useful to have a separate consent form for such purposes. Specific information that should be provided in the consent is provided in the American Psychiatric Association Committee on ECT 2000 report (American Psychiatric Association 2001).
