[Integral psychopathological model for impulse-control disorders in children, adolescents and young adults with schizophrenia].

Integral model for impulse-control disorders in schizophrenia is based on the data of examination of 200 patients who developed schizophrenia in childhood (14%) and adolescence (86%). The model comprises 4 components corresponding to the disorders variety. Phenomenological component (FC) reflects various pathological phenomena (sexual, eating, etc); typical psychopathological component (TPC) concerns mechanisms of their realization (impulsive, compulsive, obsessive, overvalued and transitional); processive component (PC) is represented by typical psychopathological traits comorbid with other psychopathological symptoms; evolutive component (EC) characterizes drive deviations, i.e. such manifestations that do not reach pathological level. FC stability allows considering it as a core in conventional space of the model, being surrounded by the other three components--TPC, PC, EC, thought to be marginal ones. Thus, impulse-control disorder dynamics in schizophrenia occurs due to change of its marginal components.
