The author suggests a conception that considers the etiopathogenesis of psychogenic psychosomatic disorders as a chain of interacting factors. The main patterns of it are stressful life events, personality, psychotype, somatotype, systemic/organic deficit. Mechanisms of stable pathological state join this chain into a "vicious circle" of psychosomatosis. Based on the ontogenetic approach, the author suggests a 5-level system of the complex (psychosomatic) treatment of these disorders. The system integrates pharmacological treatment, neuropsychological correction, syndromal psychological correction of alexithymia and emotional sphere, modification of behavior and personality-oriented psychotherapy.
