title: Pain during transcranial magnetic stimulation in youth.
abstract: Pain or discomfort at the site of stimulation is a common side effect of transcranial magnetic stimulation. Relevant physiology and predisposing factors have not been adequately described. Literature regarding work with minors is even more limited. The authors present two cases from a child and adolescent neurophysiology transcranial magnetic stimulation protocol and one case from a therapeutic study of repetitive transcranial magnetic stimulation in adolescents with treatment-resistant major depressive disorder. Relevant literature is reviewed. Potential subjects, parents, and study teams should be well aware of this potential side effect in child and adolescent populations. Subjects with anxiety disorders may be prone to pain during these procedures. Further work could assist in identifying predisposed individuals, refining the informed consent process, and implementing procedures to minimize discomfort.
