Study: Decreased proteins, not amyloid plaques, tied to Alzheimer’s disease

Researchers from the University of Cincinnati found that low levels of soluble amyloid-beta protein in the brain, rather than its buildup into plaques, are associated with cognitive decline and Alzheimer's disease. Patients with high levels of soluble amyloid-beta showed improved cognitive outcomes, contradicting previous theories.

SuperAger brains contain ‘super neurons’

Researchers found significantly larger neurons in the brain's memory region of SuperAgers compared to cognitively average peers, individuals with early-stage Alzheimer's disease, and younger individuals. These larger neurons were spared from tau tangles, a hallmark of Alzheimer's disease, suggesting they may maintain structural integrity.
