Background:
This study examined cognitive side effects of maintenance electroconvulsive (ECT) in comparison with maintenance pharmacotherapy after index ECT.
Method:
Clinical outcome data and neuropsychological measurements were compared in 11 maintenance ECT patients and 13 control patients treated with maintenance pharmacotherapy after index ECT. Data were gathered in a prospective naturalistic study during follow-up.
Results:
There were no significant differences in patient characteristics and effects of index ECT between groups. In control patients treated with maintenance pharmacotherapy, cognitive function as well as depression ratings remained stable. During maintenance ECT neuropsychological test performance and depression ratings improved slightly but not significantly.
Conclusions:
Neuropsychological functioning during the maintenance phase of treatment did not differ between the two treatment groups. Cognitive function remained stable during maintenance ECT.
