Study and announcement
The University of Florida reported on August 5 that a Cell Reports Medicine study analyzed 230 postmortem human brains. Researchers examined corpora amylacea, structures that can reflect glycogen storage, alongside Alzheimer-related pathology and brain regions.
Findings
In the postmortem tissue, glycogen-related structures were associated with tau pathology, and glycogen patches were also observed at early neuropathological stages. Because the study examined brain tissue after death, it cannot establish whether these changes preceded or followed disease pathology.
Limits and disclosures
Postmortem tissue associations cannot show that diet or carbohydrate intake caused Alzheimer’s disease or that changing diet would alter risk. The university announcement is dated August 5 and refers to the same-day journal paper; this is a mechanistic brain-tissue finding, not a clinical nutrition intervention.
