Abstract
Objective: Review current evidence regarding the application and benefits of Electroconvulsive Therapy (ECT) in patients with bipolar affective disorder. Bibliographic review: The mechanisms of action of ECT in the treatment of bipolarity are not fully elucidated and this practice is commonly discredited by the medical community itself, generating disbelief as to its effectiveness and safety. However, there are strong correlations with this therapy and significantly improvement in depressive, maniac and mixed-state symptoms. The response rate is, in general, equally efficient, or superior to the usual mediation, varying according to specific groups or complexity of the condition. ECT is also capable of reducing the occurrence of mood swings, being also effective as maintenance therapy. A greater efficiency seems to be linked to factors, such as higher wave velocity, unilateral electrode positioning and advanced age. Final considerations: Despite the beneficial effects, ECT is not exempt from collaterals. Further studies should be proposed to develop more assertive guidelines on the topic.
