Spontaneous length of depression and response to ECT
Psychological Medicine
|November 1, 1977
Abstract:
Electro-convulsive treatment (ECT) was therapeutically ineffective in 27 (20%) of 136 depressed patients. Failure to respond occurred in long-lasting depressions and in patients with a history of long-lasting depressions. In these cases the depression lasted at least 6 months. The hypothesis is proposed that ECT is effective only when given within 6 months of thespontaneous end of the depression. Clinical and nosological implications are discussed.
