Age-dependent cognitive defects caused by local brain lesions of various geneses

The results of neuropsychological analysis of 808 children and adolescents 7–18 years of age were studied. Among the test subjects, 689 children were patients with local brain lesions (tumors, arachnoid cysts, vascular pathology, and congenital hydrocephaly) and 119 children were healthy. Both patients and healthy subjects were divided into four age groups: junior school age (7–9 years), prepubertal age (10–12 years), pubertal age (13–15 years), and senior school age (16–18 years). Cognitive defects were found and demonstrated to depend on the test subject’s age and the type of brain pathology.
