Alzheimer's Takes a Financial Toll Long Before Diagnosis, Study Finds

Long before people develop dementia, they often begin falling behind on mortgage payments, credit card bills and other financial obligations, new research shows. The New York Times: A team of economists and medical experts at the Federal Reserve Bank of New York and Georgetown University combined Medicare records with data from Equifax, the credit bureau, to study how people's borrowing behavior changed [PDF] in the years before and after a diagnosis of Alzheimer's or a similar disorder. What they found was striking: Credit scores among people who later develop dementia begin falling sharply long before their disease is formally identified. A year before diagnosis, these people were 17.2 percent more likely to be delinquent on their mortgage payments than before the onset of the disease, and 34.3 percent more likely to be delinquent on their credit card bills. The issues start even earlier: The study finds evidence of people falling behind on their debts five years before diagnosis. "The results are striking in both their clarity and their consistency," said Carole Roan Gresenz, a Georgetown University economist who was one of the study's authors. Credit scores and delinquencies, she said, "consistently worsen over time as diagnosis approaches, and so it literally mirrors the changes in cognitive decline that we're observing." The research adds to a growing body of work documenting what many Alzheimer's patients and their families already know: Decision-making, including on financial matters, can begin to deteriorate long before a diagnosis is made or even suspected. People who are starting to experience cognitive decline may miss payments, make impulsive purchases or put money into risky investments they would not have considered before the disease.
