SLEEP 2020, online

I have the honor to present oral in this year's SLEEP meeting again! The topic is about my most recent research interest -- daytime napping. Many results have been touched in the online AAIC oral presentation this year. In this SLEEP presentation, I've added some most recent updates on the potential bi-directional relationship between longer daytime napping and cognitive decline. Based on a structural equation model, the two processes seem to drive each other with aging, as longer daytime napping was associated with next year more cognitive decline, and the other way around, more cognitive decline was associated with daytime napping prolongation in the subsequent year.

I attended the live Q&A session as well.

q&aIt appears that audience has a great interest in the link between daytime napping and cognition/dementia. I've amphasized on our finding about the bi-diretional relationship, and mentioned that there is far from drawing causation at this moment. A lot more to be done in order to confirm whether excessive daytime napping is a risk factor to promote this process, or accelerated this progression, or it works as a biomarker to help monitor the disease process.

The story was covered by a MedPage Today media report. Check this if you'd like to read more!
