A new model of Alzheimer’s disease has been proposed, which could speed up efforts to understand and cure the complex condition – while bringing all manifestations of the condition under one unifying theory.

Researchers from Arizona State University suggest that stress granules – protein and RNA clumps that form around cells in stressful conditions due to genetic and environmental risk factors – are the primary culprit behind the disease.

In their new study, the team reviewed data from multiple health databases and past papers – particularly a 2022 study on Alzheimer’s progression – to identify widespread changes in gene expression that come with it.
