title: The relationship between stressful life events and cognitive function in HIV-infected men.
abstract: Previous studies have demonstrated an impact of stress on immune function, and recent studies have suggested an adverse effect of stress on the brain. However, no previous study has examined the impact of stress on cognitive function. This article examines the relationship between stress and cognitive function in 82 HIV-negative subjects and 251 HIV-positive subjects. Subjects completed a comprehensive neuropsychological examination, measures of anxiety and depression, and a measure of stressful life events. After controlling for the impact of anxiety, depression, age, and education, stressful life events were related to cognitive impairment only among the HIV-positive subjects. The data were interpreted in the context of previous studies that have demonstrated an adverse effect of stress on the brain and suggest that this adverse impact may be expressed in the setting of a compromised immune system. Furthermore, this analysis suggests several implications for patient management.
