[Dynamic psychiatric interpretation of a disease model of trichotillomania].

Every patient's "communal existence" allows to interpret deviations of behavior such as trichotillomania as a disturbance of interaction. When the child begins to wangle out of the dual union between mother and child it needs ways to delimitate itself, If the mother does not concede this demarcation (f. i. because she does not want to release the child from the symbiosis and therefore is "overprotecting") the child often becomes a victim of despair and, later on, of perplexity. At last it uses the own body as "Vis-a-vis". The accumulated aggressiveness is then worked off motorically by means of trichotillomania. In this way despair and perplexity in the field of interaction are passed on so to speak "atmospherically" to the mother, who in turn, having arranged treatment, transfers them on to the doctor. It is discussed how the area of irritation can be dissolved.
