Abstract Number: Esoc2026ot62 Neuropsychological Disorders in Children With Consequences of Stroke

Abstract Background and aims Acute cerebrovascular accidents have long-term consequences that negatively affect psychological development, leading to social and academic maladjustment of the child. Methods The aim of our study was to evaluate the extent of cognitive impairment in children with post-stroke sequelae. Results Twenty-three children aged 3-7 years with post-stroke sequelae were examined. The control group consisted of 15 apparently healthy children. Neuropsychological assessment of cognitive function was conducted using the method developed by A.R. Luria. Conclusions All children exhibited cognitive impairments related to the lesion site. Fifteen children with post-stroke sequelae of the anterior regions of the brain exhibited impairments in programming and control, difficulty understanding the hidden meaning of stories, perseveration, slipping into irrelevant associations, impaired smoothness of voluntary movements, impaired selectivity of traces, impaired generalization based on situational cues, and impaired control of auditory-verbal and visual memory. These findings indicate damage to the diencephalic level, which corresponds to functional block I. Eight children with sequelae of posterior brain stroke demonstrated impairments in understanding logical-grammatical relationships, impaired perception of images and letters, difficulty maintaining the order of stimuli in auditory-verbal memory, impaired spatial organization of movements and actions, and a narrowing of the immediate visual memory capacity. Reduced stability of visual memory traces to interfering stimuli, indicating damage to functional blocks II and III of the brain. Conflict of interest
