- High salt intake linked to faster memory decline in one group, study finds
A six-year study of over 1,200 older adults found that higher dietary sodium intake was linked to faster episodic memory decline in men, but not women. Researchers suggest sodium intake may be a modifiable risk factor for cognitive decline in older males, potentially due to its role in blood pressure regulation.

A 2011 study linking amyloid-β to Alzheimer's memory loss was retracted from Neurobiology of Aging, joining multiple other retracted studies on the same topic. Failed drug trials targeting amyloid-β and allegations of scientific fraud highlight ongoing controversies in Alzheimer's research.
