title: Neuropsychologic functioning of human immunodeficiency virus-infected children with hemophilia.
abstract: Efforts to detect subtle but objective neuropsychologic deficits could clarify the early involvement of the central nervous system and the progression of human immunodeficiency virus (HIV) infection in older children and young adolescents. Baseline examinations of 63 children and adolescents with hemophilia were conducted by examiners unaware of HIV status or staging or of our study's major hypotheses. They measured six domains of neuropsychologic functioning (motor, language, memory, attention, visual processing, and problem solving), and no differences between groups of similar age, race, and socioeconomic status defined by HIV seropositivity (n = 25) and HIV seronegativity (n = 38) were revealed. A high incidence of subtle neuropsychologic deficits relative to (1) age norms and (2) individual cognitive potential was found on measures of motor performance, attention, and speeded visual processing within both infected and uninfected groups. On the basis of these baseline data, it seems premature to attribute early, subtle neuropsychologic deficits in seropositive children with hemophilia to the central nervous system effects of HIV infection.
