There are no published data about transcranial magnetic stimulation (TMS) as a treatment for psychiatric disorders in young persons. The aim of this article is to collate available information about TMS in this population. Information was sought, by placing a message on the TMS Listserver, from investigators who had used TMS in patients 18 years of age or younger. Only one group reported experience in this area; it had treated seven patients, ages 16-18 years. Three patients had unipolar depression, three had schizophrenia, and one had bipolar disorder. Five of the seven patients had improved by the conclusion of the TMS course. Adverse events were reported in one patient. Further studies are needed first to investigate systematically the safety of TMS in children and adolescents and second to examine its potential therapeutic effects in this population.
