BRAIN BIOELECTRICAL ACTIVITY IN CHILDREN WITH MENTAL RETARDATION AT ACTIVE HERPES VIRUS INFECTION
Institute of Neurology, Psychiatry, Narcology of NAMS of Ukraine, Kharkiv, Ukraine
In recent years, increase in the requirements for intellectual development of the child has been observed. Mental retardation is an acute and pressing issue in child psychoneurology. Within a framework of investigation of the role of chronic infections caused by different viruses of herpes family in mental and speech retardation electroencephalograpy (EEG) was performed in 50 children (study group) with this pathology aged 5−7 years. The findings of the main group were compared with the controls (20 children aged 5 to 7 years without cognitive impairment). The aim of the work was to study the features of EEG in children with mental retardation and establishing the influence of chronic herpes infection on bioelectric activity of the brain. It was found out that long−term pathological manifestations of bioelectric activity were observed in all 50 investigated children of the main group. Children with mental retardation compared with the controls had more prominent paroxysmal and cerebral cortical disorders. In children with severe degrees of mental retardation greater representation of epileptiform manifestations was noted. Pathological manifestations of EEG in children with cognitive disorders and persistent active herpes infection occurred more frequently than in children without the signs of activity. The investigation failed to allocate a statistically significant correlation between the EEG findings and the type of herpes infection.
Key words: mental retardation, children, herpes virus infection.
