MINIMAL CEREBRAL DYSFUNCTION: PREVALENCE, RISK FACTORS, CLINICAL, NEUROPHYSIOLOGICAL AND NEUROPSYCHOPHYSIOLOGICAL ASPECTS

Abstract

According to the survey of 1155 children of 2-8 years attending nurseries and schools, the prevalence of minimal cerebral dysfunction (MCD) in Irkutsk was 11,3 %on average, 14 % in toddlers, 11,8 % in preschool age and 8,3 % in the early school age. Complex clinical-neurophysiological and neuropsychophysiological research was carried out in 173 children of 2-8 years with MCD. Risk factors, clinical features and rates of higher mental functions in toddlers and children of preschool and early school age with MCD were investigated. 3 clinical variants of MCD were detected - regredient, regredient with mild cerebral organic insufficiency and progredient. Two types of clinical flow (favorable and unfavorable) were defined; the regredient variant of MCD refers to the favorable one. The possibility of early revealing of clinical, neurophysiological and neuropsychophysiological peculiarities was showed, that promoted increase of efficiency of treatment-rehabilitation measures in children with MCD.
