Positive Response to Bilateral Sinusoidal ECT in Unilateral and Bilateral Brief-pulse "ECT-Resistant" Depressive Illness.Price, Trevor R. P. M.D.; McAllister, Thomas W. M.D.; Peltier, Deborah M.D.; Kraft, Alan M.D.Convulsive Therapy: 1986 Case Report: PDF Only Abstract Abstract Summary: Six patients who failed to respond to what would ordinarily be considered therapeutically effective courses of sequential unilateral nondominant (mean number 10) and bilateral brief-pulse electroconvulsive therapy (ECT) (mean number 10) with electroencephalographic (EEG) monitoring of seizure duration (all seizures >30 s) subsequently received courses of bilateral sinusoidal ECT (mean number 6) and responded well. Some theoretical implications and clinical considerations raised by these cases are discussed. (C) Lippincott-Raven Publishers.
