Deep Sleep May Slow Alzheimer Progression

The new study reveals that deep sleep plays an important role in protecting the brain from the development of Alzheimer's disease. Higher levels of orexin during sleep are associated with increased disease progression and the accumulation of beta-amyloid and tau proteins. Researchers have shown that patterns of deep sleep, particularly sleep spindles and slow waves, may have a protective effect and help reduce the risk of disease development. Conversely, elevated orexin levels during sleep are linked to worsening symptoms over three years, with women exhibiting higher orexin levels than men. The findings highlight the importance of enhancing sleep quality and regulating orexin levels as potential strategies to limit the spread of Alzheimer's. Further studies are needed to develop innovative therapeutic approaches.
