Neurological diseases, mental disorders and inherited developmental abnormalities held a prominent place in the structure of primary children disability. Children cerebral palsy is the main cause of children disability, its prevalence reaching 2-3.5 cases per 1000 children. This disease has the noticeable negative consequences (both clinical and economic). Adherence to treatment means patient's compliance with doctor's orders including taking medicines as prescribed, sticking to diet and changing life style habits. While the adult patient plays an active role in doctor-patient alliance, the child patient interacts with the doctor together with his/her family. The authors consider the effect of different factors on the adherence basing on the analysis of 270 questionnaires completed by persons involved in the treatment of minor patients.
