Cognitive functions and complaints in HIV-1 individuals treated for depression.
Progressive neuropsychological dysfunction and complaints of cognitive difficulty frequently accompany HIV-1 infection. Providing appropriate treatment to HIV-1 patients requires determination of the extent to which the presentation of cognitive complaints reflects HIV-1-associated neuropsychological abnormalities or represents expression of depressive symptomatology. We prospectively treated 75 HIV-1 patients who were not demented but met criteria for major mood disorder with antidepressants for 12 weeks and compared pretreatment and posttreatment measures of depression, cognitive complaints, and neuropsychological performance. Complaints of difficulty with memory and attention were found to be independent of neuropsychological impairment, whereas memory complaints were highly correlated with severity of depression. Cognitive complaints declined significantly across the course of treatment for those patients who responded to antidepressant treatment. All patients, regardless of antidepressant treatment response, exhibited parallel improvement on 12-week follow- up neuropsychological examination. These findings suggest that treatment of depression affects cognitive complaints in HIV-1 individuals and that cognitive complaints of patients in asymptomatic or early symptomatic stages of HIV-1 infection may signal the need for evaluation of depression. In patients with more advanced HIV-1 infection, investigation into the basis of cognitive complaints may require a dual assessment of mood disturbance and neuropsychological status.
