Abstract. The article reveals the issues of etiology, theories of development and pathogenesis of depression, both
medical-biological and psychological. The author describes the main psychological predictors of depression, as well as
pathogenic mechanisms associated with functional deficiency of the serotonergic system and with disregulation of the
noradrenergic system. The author analyzes the genetic polymorphism which predisposes to more pronounced development
of depressive symptoms and development of suicidal behavior in stressful situations, as well as to the violation of
neurotransmitter functioning under stress. The article considers the conjugation of clinical characteristics of depressive
disorders with immunological, neurotransmitter and hormonal parameters, involvement of these homeostatic systems in
the mechanisms of psycho-neuro-immunomodulation and in the pathogenesis of depressive disorders. A modern approach
to the treatment of depression, suggesting the combination of different methods of antidepressant therapy (including
their classification) and psychotherapeutic care. The author analyzes the variants of somatized depressive reaction,
related to latent nature of the disease’s course that may be important for non-medical health specialists.
Key words: depression, monoamine theory, serotonin, noradrenaline, antidepressant drugs, psychotherapy, models of “learned helplessness”, cognitive model of depression, tranquilizers, suicidality.
