Researchers are studying the brains of a subset of people with asymptomatic Alzheimer’s disease who, despite having amyloid plaque and tau buildup postmortem, experienced no diagnosable dementia symptoms while they were living.

Evidence Mounts for Alternate Origins of Alzheimer’s Disease Plaques
A breakdown in how brain cells rid themselves of waste precedes the buildup of debris-filled plaques known to occur in Alzheimer’s disease, a new study in mice shows.
Eyes Provide Peek at Alzheimer’s Disease Risk
Amyloid plaques found in the retinas of eyes may be an indicator of similar plaques in the brain, a hallmark of Alzheimer’s disease, and may provide a more visible biomarker for detecting disease risk.
Do Some Diabetes Drugs Reduce the Risk of Alzheimer’s?
MINNEAPOLIS – People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer’s disease, when compared to both people with type 2 diabetes not taking the drugs and people without diabetes. The new study, published in the August 11, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology, also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups.
