A new study published in Alzheimer’s and Dementia: Journal of the Alzheimer’s Association compared 13 brains who had Alzheimer’s and died with the brains of seven people who didn’t have it.

They specifically examined the parts of the brain involved in keeping us awake during the day where they found people who had Alzheimer’s had deterioration in being wakeful.

Researchers conclude there is a more direct biological pathway between Alzheimer’s and daytime sleepiness, which mean excessive napping could be early warning signs.

However, scientists say there needs to be more research on how much time lapses between when sleep changes and memory loss begins.
