The single best predictor of Alzheimer’s disease is chronological age. Yet of NIA’s $4.5B FY2025 budget, about 60% goes to Alzheimer’s and related dementias; only 9% to the Division of Aging Biology, which funds the basic mechanisms of aging itself. The insider joke is that the “A” in NIA stands for Alzheimer’s. The deeper and sadder joke: when you fit cognitive trajectories within the subset of people who go on to develop AD, about half of the variance in their test scores is accounted for by chronological age alone. We’re spending seven times more on the disease than on the clock — and the disease is mostly the aging clock. Go figure. |
