June 12 (UPI) -- Older adults diagnosed with dementia lose their ability to assess how well they manage their finances, according to a recent study I co-authored in The Gerontologist. In comparison, people of the same age who don't have dementia are aware of their financial abilities - and this awareness improves over time.
For our study, we used data from over 2,000 adults in the U.S. age 65 and older, collected during a long-term study on aging. We focused on how participants' financial skills changed over time. The study began in 1998 and is still running, but we probed data collected between 1998 and 2009.
Participants were assessed at one year, two years, five years and 10 years for their ability to carry out everyday tasks, including ones that required handling money. For example, they had to calculate the cost of a gym membership and a store discount rate, fill out part of a tax return and assess the cost of medical services. They also rated how well they thought they could do everyday financial tasks. Initially, none of the participants were diagnosed with dementia, but over the course of the decade, 87 participants, or 3.1%, received a dementia diagnosis.
We found that even though participants' performance on financial tasks declined as they aged, older adults who did not have dementia and older adults who had mild cognitive impairment were appropriately aware of their financial abilities. What's more, that awareness increased over time. However, participants who were diagnosed with dementia during the study and experienced severe cognitive decline often misjudged how well they performed financial tasks.
