Evidence for less improvement in depression in patients taking benzodiazepines during unilateral ECT

Among 48 patients with diagnoses of depression according to DSM-III, there
was a significant relation between therapeutic failure of unilateral ECT,
as measured by scores on the Hamilton Rating Scale for Depression, and the
concomitant use of a benzodiazepine. Of the 34 patients who showed a good
therapeutic response to unilateral ECT, those taking benzodiazepines had
smaller changes in their Hamilton depression ratings from before treatment
to after treatment and were more symptomatic at the end of the course of
ECT. Thus, when patients take benzodiazepines during a course of unilateral
ECT, the maximum therapeutic response may be compromised.
