ST. LOUIS, Mo. (KMOX) – Sleep disruptions may be among the earliest indicators of Alzheimer’s disease, according to new research out of Washington University School of Medicine.
This mouse study found that when the first signs of Alzheimer’s plaques appear in the mouse’s brain, they got less sleep, in many cases, they were awake half the time they should have been sleeping.
Senior researcher David Holtzman says this study could have huge implications for humans:
“Its possible that as they’re developing the earliest stages of Alzheimer’s disease, the disease starts before the actually cognitive decline. So perhaps sleep abnormalities might be occurring in people who are other wise still normal.”
Holtzman’s team now is completing similar sleep studies in humans.
