Clinical relevance of electroconvulsive therapy (ECT) in adolescents with severe mood disorder: evidence from a follow-up study.

Given the limited knowledge on the long-term outcome of adolescents who receive electroconvulsive therapy (ECT), the study aimed to follow-up adolescents treated with ECT for severe mood disorder. Eleven subjects treated during adolescence with bilateral ECT for psychotic depression (n = 6) or mania (n = 5), and ten psychiatric controls matched for sex, age, school level, and clinical diagnosis, completed at least 1 year after treatment a clinical and social evaluation. Mean duration between time of index episode and time of follow-up evaluation was 5.2 years (range 2-9 years). At follow-up: (1) all patients except two in the control group received a diagnosis of bipolar disorder. (2) Fifteen patients had had more than one episode of mood disorder. (3) The two groups did not differ in social functioning nor school achievement. (4) Impact on school achievement was related to the severity of the mood disorder rather than ECT treatment. The results suggest that adolescents given ECT for bipolar disorder, depressed or manic, do not differ in subsequent school and social functioning from carefully matched controls.
