MEASUREMENT OF DEPRESSION AND NEUROPSYCHOLOGICAL IMPAIRMENT IN HIV-1 INFECTION

Depression and neuropsychological (NP) impairment were examined in 30 HIV-1 seropositive symptomatic, 15 seropositive asymptomatic, and 14 seronegative control participants. Items on the Beck Depression Inventory (BDI) were separated into somatic and affective components to examine effects of illness on depression. Twenty-two NP tests tapped motor and psychomotor function, cognitive flexibility, and memory. The symptomatic seropositive group had the highest mean depression scores. However, these group differences were seen with the somatic component, not the affective. No significant correlations were obtained between NP tests and the affective component. Although 3 of 11 psychomotor measures were modestly correlated with the BDI total and somatic component, depression was generally unrelated to NP performance.
