Sleep Disturbances and Psychomotor Decline in HIV

Sleep disturbances may contribute to cognitive and psychomotor impairments. 50 HIV-positive and 50 HIV-negative adults were assessed on cognitive performance and sleep hygiene. The HIV-positive group performed more poorly on cognitive measures; however, no group differences were found for the sleep variables. In the HIV-positive group, indicators of sleep disturbance were correlated to various measures of cognitive functioning and depression.
