Abstract

• Magnetic resonance imaging was used to compare male subjects seropositive for antibody to human immunodeficiency virus type 1 (HIV positive), with and without medical symptoms, with two groups of men who were seronegative (HIV negative). The control subjects included men at high risk for exposure to HIV-1 and those at low risk. None of the HIV-positive subjects met criteria for HIV-associated dementia or had detectable opportunistic brain disease. Quantitative image-analytic techniques were used to estimate volumes of ventricular and cortical cerebrospinal fluid, cerebral white matter, and cortical and subcortical gray matter structures. Relative to low-risk group control subjects and asymptomatic HIV-positive subjects, nondemented but medically symptomatic HIV-positive subjects showed significant increases in cerebrospinal fluid, reduced volume of cerebral white matter, and reduced cerebral gray matter volumes. Unexpectedly, however, some cerebrospinal fluid increases and gray matter volume decreases were present in the seronegative high-risk control subjects as well.
