Movement Disorders in the Structure of the Different Mental Processes Types in Child with Opsoclonus-Myoclonus Syndrome

Opsoclonus-myoclonus syndrome (OMS) is a rare and often relapsing neurologic illness with onset in early childhood. Patients with OMS have longitudinal mental development disturbances and features of emotional and behavioral state. Interruption of the normative mental development is determined by movement disorders (primary defect), which establish new conditions for child's life for a long time. Case study of the child with OMS and the discussion of movement disorders in the structure of the different mental processes types in this disease are presented. Movement disorders (primary defect) and their effects (secondary and other defects) affecting mental development are discussed (based on the levels of movements coordination concept by N.A. Bernstein). The research detects mistmatch between levels of movements coordination (intactness of higher levels and disturbance of lower levels), which important for prospective analysis of the mental disorders mechanisms in children with OMS.
