Insomnia and cognition – trends in older adults


  • Probable insomnia disorder (PID) is associated with reduced cognitive function, particularly memory recall, and greater frequency of comorbidity in adults aged >45 years.

Why this matters

  • Findings highlight the need for increased awareness of the impact of insomnia on cognitive functioning in older adults.

  • This large-cohort study provides a foundation for future studies examining the link between insomnia and cognitive decline.
