    Aging Brain, More Trouble With Financial Decisions?

    Older people also tend to tolerate less financial risk, research suggests

    MONDAY, Sept. 30 (HealthDay News) -- Years of research have produced conflicting findings on aging's effects on brainpower. Now, a new study says that people aged 65 to 90 are significantly less likely than their younger counterparts to make what researchers define as rational decisions regarding money.

    Not surprisingly, they're also more averse to financial risk than middle-aged people, but not in all situations, the investigators found.

    Families, doctors and other caregivers "should be aware of these profound differences" in how older people make decisions compared to younger people, said study co-author Ifat Levy. She cautioned that the tests used in the study have limitations, however, and "further research is needed to directly relate these measures to real-life behavior."

    At issue is the ability of seniors to consider risk when it comes to money.

    There's some evidence that some types of decisions in general actually do improve with age. "It seems that older adults may be better in decisions that rely mainly on prior experience and knowledge," explained Levy, an assistant professor of comparative medicine and neurobiology at Yale University.

    Indeed, another study published recently in the September issue of the journal Psychology and Aging found that seniors can make better decisions than younger people because they know more. But their brains also work more slowly, and they need more time to figure out complex financial situations, that study also found.

    In the new study, researchers gave test questions to 135 people in the age groups of 12 to 17 (adolescents), 21 to 25 (young adults), 30 to 50 (midlife adults) and 65 to 90 (older adults).

    "Some of the choices were between gains: For example, would you prefer to receive $5 for sure or to play a lottery with a 50 percent chance to win $20?" Levy said. "Other choices were between losses: For example, would you rather lose $5 for sure or take a 25 percent chance of losing $50?"

    One question had a "correct" answer, she noted. It asked participants to choose between winning $5 for sure or playing a lottery that would award $5 or nothing. "A participant who is interested in making money should always go for the sure amount in this case," Levy said.
