We have studied cerebrospinal fluid obtained from 38 homosexual or bisexual men participating in a prospective study of the neuropsychological disorders associated with human immunodeficiency virus (HIV) infection. Twenty‐two subjects had neuropsychiatric findings and seropositivity, 11 asymptomatic subjects had seroconverted within 6 to 24 months, and 5 subjects were seronegative controls. Only 1 had acquired immunodeficiency syndrome‐related complex, and none had the acquired immunodeficiency syndrome when intially studied. There was a high rate of cerebrospinal fluid abnormalities in men with neuropsychiatric findings, including pleocytosis (41%), elevated IgG and IgG index (47%), and oligoclonal bands (18%). Even in the absence of neuropsychiatric findings, the asymptomatic HIV‐seropositive subjects frequently had spinal fluid abnormalities. Of those with neuropsychiatric findings, HIV p24 antigen was detectable in cerebrospinal fluid in only 1 individual, yet HIV was isolated in 11 of 16 (69%) compared to 2 of 7 (29%) of those without neuropsychiatric findings. The identification of cerebrospinal fluid abnormalities in individuals known to have become infected within 6 to 24 months supports the hypothesis that the nervous system is an early target for HIV.
