Table 1 Demographics of subjects included in the study (NCyoung: subjects with normal cognition under the age of 60; HIV-NC: HIV-infected subjects with normal cognition; HAND: HIV-infected subjects with cognitive impairment; NColder: subjects with normal cognition at or over the age of 60; MCI-AD: subjects with mild cognitive impairment and CSF biomarkers consistent with Alzheimer’s disease). *p ≤ 0.003 vs. NCyoung.
