Research team links sleep disorders and napping to higher neurodegenerative disease risk

Yonsei University and Severance Hospital researchers analyzed UK Biobank data from 170,000 people, finding sleep disorders raise neurodegenerative disease risk by 32%, with NREM parasomnia increasing risk 3.46 times.
Frequent napping, daytime sleepiness, and difficulty waking up also significantly heighten risk, especially in insomnia and sleep apnea patients. The team developed a predictive model validated on over 7,000 Severance Hospital patients.
The study highlights the importance of diagnosing and managing sleep disorders for early prevention of diseases like Alzheimer's and Parkinson's, and demonstrates the value of sleep disorder information in predictive healthcare models.

How Sleep Disorders and Napping Patterns Predict Neurodegenerative Diseases: A 32% Risk Increase Revealed
Overview
A major 2026 UK Biobank study found that people with sleep disorders have a 32% higher risk of developing neurodegenerative diseases like Parkinson's and Alzheimer's. REM Sleep Behavior Disorder (RBD) is especially predictive, with up to 90% of cases progressing to Parkinson's or Lewy Body Dementia within 10-12 years. Disrupted sleep harms the brain's glymphatic system, which clears toxic proteins during deep sleep, leading to protein buildup linked to disease. Circadian rhythm disruptions worsen this by altering hormone levels, increasing stress and inflammation. Treating sleep apnea with CPAP and using bright light therapy to improve circadian rhythms show promise in reducing neurodegenerative risk.
