A new discovery from U.S. researchers could change how we understand—and potentially treat—dementia. It all comes down to sugar in the brain and how it’s processed.
Brain Sugar Could Play a Protective Role
Researchers believe that glycogen, a type of sugar found in the brain, may help protect nerve cells from damage related to dementia.
Alzheimer’s Disrupts Sugar Breakdown
In both mice and human brains with Alzheimer’s, scientists found that glycogen wasn’t being broken down properly, leading to harmful buildup.
Tau Protein May Interfere With This Process
One theory is that tau, a sticky protein known to drive Alzheimer’s, binds to brain sugar and blocks its breakdown.

Loss of Sugar Breakdown Weakens Brain Defenses
Without proper sugar metabolism, the brain may lose a key defense mechanism that helps it resist disease and degeneration.
A New Avenue for Treatment
Researchers suggest that future treatments could aim to restore the brain’s ability to break down glycogen, slowing the effects of dementia.
Dietary Impact Could Be Explored
The discovery raises the possibility that diet might influence how the brain processes sugar, though more research is needed.
Findings Based on Mouse and Human Brains
The research was conducted using samples from both mice and people diagnosed with Alzheimer’s, adding weight to the findings.

A Fresh Perspective on Alzheimer’s
Instead of focusing solely on plaques and tangles, this study points to energy metabolism as a potential factor in dementia development.
Leading Researchers Behind the Study
The study was carried out by scientists at the Buck Institute for Research on Aging, a world leader in age-related brain research.
