A new study has revealed a connection between deep sleep, a neuropeptide called orexine, and the progression of Alzheimer’s disease. The research indicates that sufficient deep sleep may correlate with a slower rate of advancement of Alzheimer’s. The study highlights the importance of understanding the biological mechanisms linking sleep and neurodegenerative diseases. The findings suggest potential avenues for therapeutic interventions focused on improving sleep quality in individuals at risk of or diagnosed with Alzheimer’s. Further research is needed to fully elucidate the role of orexine and deep sleep in preventing or delaying the onset of cognitive decline. This article originally appeared on Kapitalis.
