Repetitive transcranial magnetic stimulation in the treatment of depression in adolescents: An open-label study

Objective: This open-label pilot study examined repetitive transcranial magnetic stimulation as a possible treatment of adolescent resistant depression. Method: Nine adolescents (aged 16-18 years) with severe resistant depression (determined by SCID) were recruited, and their depression, suicidality, and cognitive functions were evaluated before, during, and after a course of twenty 10-Hz, 2-second trains (intertrain intervals of 58 seconds) given over 20 min/d over 14 working days. Results: Lower levels of depression with progression in therapy were recorded by both the Beck Depression Inventory and Child Depression Rating Scale measures (F-1.7,F-14.01 = 4.52, P < 0.05; F-4,F-32 = 6.645, P < 0.01, respectively). Three patients reached the primary outcome measure of less than 30% reduction in their Child Depression Rating Scale. The effect on suicidality was not significant. Side effects were considered mild. Conclusions: Repetitive transcranial magnetic stimulation might be a possible therapy for adolescent depression. Our preliminary findings warrant double-blind, controlled studies.
