Psychosomatics is one of the most common requests for psychotherapy. Mostly adults come to the psychoanalyst with this request. And in the process of analysis it turns out that the roots of this phenomenon lie deep, deep in early childhood. In infancy. That is, the “root of all troubles” should be sought in the first months of life. Psychiatry of infancy is the psychopathology of interaction. Based on this statement, we can say that psychosomatics in an infant is participation in pathological situations and interactions that are fraught with somatization in the infant. In the nosology of infancy, in addition to psychosomatics, there are motor-behavioral disorders, developmental deviations, disorders of mental and emotional manifestations, and it is important to differentiate these phenomena from each other. In infancy, 3 stages of the occurrence of psychosomatic disorders can be distinguished: - the appearance of disorders before six months of age. - before one and a half years - the age of formation of attachment, basic for the formation of object relations. - end of infancy (up to three years) Excitement can be channeled in three main ways - mental, behavioral, somatic. Obviously, psychosomatics comes into play when the first two paths lead to failure. The primary content of the psyche in general, and the unconscious in particular, is emotional (sensual) and motor representations. The volume and qualitative characteristics of these ideas, as well as the possibility of their further verbalization, depend on the quality of performance of the maternal function. There are three main pathologies of the maternal function: - Insufficient care and affection for the child, insufficient stimulation, and, as a consequence, emotional poverty in the child.- Overprotection and hyperstimulation - aimed at one of the functions of the body (for example, nutrition) - cause a violation of this function, its use as a form of interaction with the mother (for example, anorexia) - symbiosis of mother and child with the exclusion of the father from the relationship, the impossibility of separation and free emotional growth , can cause psychosomatic disorders such as asthma (self-suffocation by suppressed hatred of an equally suffocating mother) - a temporary mismatch of relationships dictated by life in modern society. If psychosomatics begins as a dysfunction of object relations, then in the second year of life it already begins to function as an autonomous psychological protection, form of behavior and response. The life of a psychosomatic child is marked by emptiness, emotional poverty or systematic separations. All of them are distinguished by various developmental delays, psychomotor disorders, massive defects of identity, including gender. They are fragmented and the fragments of their personality are loosely connected. Their main features, consistently, from infancy to adolescence and further to adulthood, can be called - background depression - dysfunction of object relations, including relationships of internal objects - low ability for mentalization. Of course, these childhood disorders cannot be perceived as a sentence and irreversible developmental disorders . Psychosomatic functioning can be overcome in later, healthy relationships with significant adults; on the contrary, it can be layered on healthy development in the form of trauma-determined pathology of a later period; pathologies can be transformed in the progressive development from one to another or evolve in the same form as asthma. For the treatment of psychosomatic diseases, it is important to know that the same somatic manifestation can be a consequence of various mental pathologies. And the same pathology can be the cause of various somatic disorders. In conclusion, we can say that the psychosomatics of infancy requires techniques that expand the tools of classical psychoanalysis, such as early joint therapy of mother and baby, and participation.
