P.310 Response to electroconvulsive therapy of different clinical features in 670 bipolar patients with depression or mixed state.

B Objectives: b The efficacy of electroconvulsive therapy (ECT) on single clinical features has been rarely investigated, except for suicidality [1]. For each construct, response and remission rates were determined among patients reaching high severity scores (>= 5; i.e. moderately to extremely severe) for the corresponding BPRS-EV item before treatment. Suicidality showed the highest remission rate, with 84.4% of patients at high risk of suicide before treatment, which were no more overtly suicidal after ECT. [Extracted from the article]
