The CNS infection by HIV-1 in infancy could be present immediately after infection or became manifest later. Microcephalia, mental retardation, pyramidal signs, humor and behavioral disorders and antiretroviral therapy complications are common. This is an observational, sectional and descriptive study about findings on neurological examination of 173 patients in a group of children and adolescents infected and exposed to HIV-1 in perinatal period. Most of them had more than one neurological finding or different diagnosis. The more common findings were: encephalopathy, mental retardation, language delay, pyramidal signs, hyporreflexia. The neurological examination was abnormal in 67% of all patients even in sororeverters. We sugest that this group has a high risk to neurological disease and the development of co-morbidity is directly correlated to clinical deterioration by HIV-1 infection.
