Summary. The purpose of this study is a review of contemporary knowledge from the field of children and adolescent psycho- somatics by using standard textbooks and journals. Data are chosen according to their importance and easy reference for a clinical study and scientific research. Psychosomatics can be defined as medicine of mutual relationships in the widest sense. It seems that factors of bio-psycho-social area participate in etiology and pathogenesis, i.e. complex genetic, developmental, psychodynamic, neuroanatomical, psychoneurophysiological, neurobiochemical, psychoneuroimmunological, psychoneuroen- docrinal, familiar, social and probably other factors. Children and adolescent psychiatry, pediatrics are mutually complementary. In the medical-psychosomatic field there is consideration in the form of spatial-operative models that have to be amended through the concepts of unconscious and preconscious as well as through a temporal-systematic perspective. A team approach will be applied in a therapy.
