PSYCHOLOGICAL FEATURES OF THE PHENOMENON OF THE VANISHED TWIN: THEORETICAL ANALYSIS

Recently scientists observe interrelation between the events which were taking place during pregnancy or, health of mother during this period and any deviations in development of the child. That experience which children get, being in mother's ute-rus, it is at the time of delivery very important as these impressions remain for the rest of life in mentality and leave an indelible print in her. Today there are many researches which produce the evidence that the fruit possesses emotional perception and actively functioning memory, and the impressions apprehended till the birth — after the birth exert impact on a mentality and style of behavior of the person during all his subsequent life. For example, Beversdorf with colleagues from department of neurology of the Medical Center of Ohio State University (USA) intensively studied genetic aspects of autism. But in the subsequent the group of scientists has decided to pay attention to social and psychological factors and has found out that the strong emotional stressor, transferred women for 21-32 weeks, with peak in 25-28 weeks, plays a huge role in origin of autism [1]. Longityudny researches show that consequences of the postponed emotional stress in a prenatal phase can be the most different. It and persuasive states, phobias, fears, a syndrome of deficiency of attention and hyperactivity, the increased aggression, tendency to asocial and suicide behavior, etc. [2]. One of strong, significant traumatic experiences in prenatal development is «the phenomenon, or a syndrome, the disappeared twin» (Vanishing twin). It is mysterious anomaly which is that during polycarpous pregnancy on a certain term, most often, in the first trimester, there is only one twin, and another for a number of reasons perishes. Thus, the problem of «vanishing twin phenomenon» and possible psychological consequences of intrauterine death of a twin. The widespread use of ultrasound in early pregnancy showed a significant prevalence of this phenomenon, which makes the problem of psychological help and support for twins who lost their siblings before birth a relevant issue.
