Dementia: Sleep problems could 'double risk' of disease in later life

  • Researchers from Cardiff University and the NIH studied over one million health records to assess sleep disorders' link to dementia risk by May 2025.
  • They aimed to clarify the sequence between sleep problems and neurodegenerative diseases, as evidence remains insufficient to confirm causality.
  • The study identified that diagnosed sleep disorders double the risk of dementia and other diseases within 5 to 15 years, independent of genetics.
  • Hazard ratios for dementia ranged from 1.15 for Alzheimer's to 2.05 for vascular dementia, showing strong associations with ICD-10 coded sleep disorders.
  • These findings suggest early sleep disorder detection offers a promising target for intervention to delay or prevent late-life neurodegeneration.
