Effects of low-dose TRH on cognitive deficits in the ECT postictal state

Published Online:https://doi.org/10.1176/ajp.151.11.1694

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.
