A recent study presented at the Alzheimer’s Association International Conference 2024 explores a possible link between sleeping on one’s back (supine position) and increased risk of neurodegenerative conditions such as Parkinson’s spectrum disorder, Alzheimer’s disease, and mild cognitive impairment. The research builds on previous findings that suggest prolonged supine sleeping might impair neurotoxin clearance from the brain, a process crucial for preventing neurodegeneration.
The study used the Sleep Profiler device to monitor participants’ sleep positions, revealing that those with neurodegenerative diseases spent over two hours a night in the supine position, compared to a control group. This finding aligns with earlier research indicating a correlation between extended supine sleep and neurodegenerative risk.
Despite these associations, the study does not establish causation. Daniel J. Levendowski of Advanced Brain Monitoring, who led the research, notes that while the findings are compelling, they only suggest a link rather than a direct cause. Other factors such as sleep apnea and sleep deprivation also contribute to neurodegeneration risk. Experts emphasize that while supine sleeping may affect neurotoxin clearance, more research is needed to understand the full implications and potential interventions for brain health.
Dr. Daniel Truong, a neurologist, stresses the importance of integrating these findings with broader lifestyle recommendations rather than viewing sleep position in isolation. Prioritizing good sleep hygiene and overall lifestyle choices remains crucial for reducing the risk of neurodegenerative diseases.
