Raeanne Moore & colleagues found that Objective and subjective sleep measures are associated with neurocognition in aging adults with and without HIV

Studies have shown that poor sleep is related to worse cognitive functioning (e.g., memory, attention) in older adults and persons with HIV. However, the relationship between sleep and cognitive functioning has not been well studied in older people with HIV. In this study we examined how sleep relates to cognitive functioning in people aged 50 and older with and without HIV. We gave 84 participants paper and pencil cognitive tests to measure cognitive functioning. To measure sleep, we gave participants watches (similar to a Fitbit watch) to measure their sleep at home for 14 days. We also had participants rate their own sleep quality using a questionnaire.

We found that sleep quality that was assessed using the watch was related to learning and memory in people with and without HIV. Sleep quality assessed using a questionnaire was associated with attention and executive functioning (e.g., problem solving, multi-tasking) but only in people without HIV. This study suggests that it may be helpful to use both questionnaires and technology (e.g., watches that track sleep) to assess sleep quality. Also, future studies should study if improving sleep (e.g., Cognitive Behavioral Therapy for Insomnia) can help improve cognitive functioning in older people with and without HIV.
