Structural Brain Plasticity in Elderly Depressed Patients Following Electroconvulsive Therapy
In Brief
A clinical study evaluating ECT, Etomidate, and 1 other intervention for Depression. Completed, enrolled 110 participants.
Detailed Summary
To study the potential neurorestorative effects of electroconvulsive therapy (ECT) in depressed patients by measuring brain derived neurotrophic factor (BDNF) serum levels and hippocampal volumes in severely depressed patients receiving ECT.
Study Details
Timeline
Interventions
ECT was administered twice a week with a constant-current brief-pulse device (Thymatron, System IV). Motor and electroencephalographic seizures were monitored to ensure adequate duration and quality. Subjects were all treated with right unilateral (RUL) ECT with stimulus intensity 6 times the initial seizure threshold (ST), as determined by empirical dose titration at the first treatment, until remission (Montgomery-Åsberg Depression Rating Scale (MADRS) (27) \< 10 in two consecutive ratings with a week interval). Subjects who failed to respond right unilateral ECT after the sixth treatment were switched to bitemporal ECT (1.5x seizure threshold).
Anesthesia was achieved with intravenous administration of etomidate (0.2mg/kg).
Anesthesia was achieved with intravenous administration of succinylcholine (1mg/kg).
