Aging is the greatest risk factor for Alzheimer's disease.
Is it true that aging is the greatest risk factor for Alzheimer's disease?
Yes. Aging is widely recognized across contemporary literature as the single greatest risk factor for Alzheimer's disease, driving cellular senescence, metabolic shifts, and neurodegeneration.
Verdict: SUPPORTED · 5 sources for, 0 against · Last checked
The retrieved papers consistently state that aging is the predominant or strongest risk factor for Alzheimer's disease and investigate cellular senescence, mitochondrial dysfunction, and hormonal loss during aging as key drivers of AD pathogenesis. There is unanimous support in the literature for this claim with zero papers refuting it.
