Abstract:
A low dose (0.5 mg) of thyrotropin-releasing hormone (TRH), a short-acting tripeptide with known analeptic properties, was administered to eight depressed patients 5 minutes after ECT session 3 or 4 in a double-blind, placebo-controlled crossover design. After TRH infusion the patients displayed selectively better performance on a battery of neuropsychological tests than they did after placebo infusion. Further exploration with pharmacological probes to mitigate ECT postictal cognitive deficits is warranted.
