Daytime napping is a common behavior especially in elderlies. There are conflict results regarding long-term health consequences and daytime napping. No prior studies have investigated how objective daytime napping changes longitudinally with aging, and how this change interacts with the progression of Alzheimer's.
We have studied this using a large cohort of elderlies with annual clinical assessment and annual assessment of actigraphy. Participants have been followed for 6 years on average, and up to 14 years. Results were presented in oral at the virtual SLEEP2020 meeting...

A new research article titled "Fractal regulation and incident Alzheimer's disease in elderly individuals" that summarizes some interesting findings from my recent studies has been online published in the journal Alzheimer's & Dementia: The Journal of the Alzheimer's Association.
Briefly, it shows that a fractal metric obtained from motor activity predicts the risk of Alzheimer's dementia around 5 years later. It also predicts faster cognitive decline.
Chandan, Dingchang, and I are now arranging a research topic in the journal Frontiers in Physiology that is related to photoplethysmography (PPG) in general and PPG-derived respiratory activity in particular. Click to see online...
