    Abstract:
    OBJECTIVE: To evaluate efficacy and tolerability of unilateral (RUL) and bilateral (BL) electroconvulsive therapy (ECT) in the elderly with depression. METHODS: Thirty-nine elderly inpatients with major depression referred to ECT were randomized into RUL or BL ECT, using high, fixed electrical doses. Cognition and depression severity were assessed before, during, and 1 month after treatment. Adverse effects were assessed after each session. RESULTS: Remission rates for RUL ECT (88.2%) and BL ECT (68.2%) were similar (P = 0.25). Reduction rates of depressive symptoms were also similar. There were no serious adverse events. There were more adverse effects in the BL ECT group (P = 0.05). BL ECT showed more short-term cognitive impairment, whereas improvements in neuropsychological scores were seen in both groups. CONCLUSION: In elderly depressive subjects, high-dose RUL ECT is as effective as BL ECT yet produces less adverse effects and less cognitive impairment.
