Abstract:
Five patients with Parkinson's disease (PD) and depression underwent electroconvulsive therapy (ECT). One patient had a myocardial infarction several hours after the last planned session and died. Of the remaining four patients, all achieved marked improvement in mood and three had markedly improved motor function as well. Improvement in motor function lasted as long as 8 weeks. ECT is helpful in treating both depression and parkinsonism but maintenance ECT is required for continued motor improvement.
