[Complementary treatment methods for depression in children and adolescents].

Depressive disorders are among the more common mental illnesses around the world, about 1- 3% of prepubertal children and 6% of postpubertal children and adolescents are affected. They markedly impair psychosocial development and are associated with higher rate of morbidity and mortality throughout life. Many physicians are unsure about which treatment approaches are effective and how the treatment should be planned. A systematic literature search was carried out in electronic databases and study registries and as a manual search. More than 450 studies (mostly randomized controlled trials = RCTs) were identified and summarized in evidence tables. The ensuing recommendations were agreed upon in a consensus conference. The review summarizes the evidence of complementary treatment methods. The evidence for complementary treatment methods (art and music therapy, sleep deprivation, exercise, electroconvulsive therapy, massage, transcranial magnetic stimulation, relaxation, bibliotherapy, computer based therapy, light therapy, omega-3 treatment) is low or there is no evidence due to missing studies or studies of poor quality. For some methods, i. e. light therapy, relaxation and stress reduction and sleep deprivation there is limited indication for effectiveness without sufficient evidence for a practical guidance. There is an urgent need for adequately informative comparative studies on treatment of depression in children and adolescents considering also complementary methods.
