A new study suggests fat deposits in the brain may play a larger role in Alzheimer's disease than previously thought. This could open a new avenue for potential treatment.

Research has long focused on proteins found abnormally clumping in brains with neurodegeneration, but targeting these clumps has so far produced mixed results . So some researchers continue to search for missing components in our Alzheimer's disease model.

"In our view, directly targeting plaques or tangles will not solve the problem; we need to restore function of immune cells in the brain," explains Purdue University chemist Gaurav Chopra.

This is based on recent research revealing that immune cells, such as astrocytes and microglia , are being disrupted by associated fat molecules. The amyloid beta pr
