Sleep and cognitive performance: cross-sectional associations in the UK Biobank.

ABSTRACT:

Objective

The relationship between insomnia symptoms and cognitive performance is unclear, particularly at the population level. We conducted the largest examination of this association to date through analysis of the UK Biobank, a large population-based sample of adults aged 40-69 years.
