Many Americans believe they are likely to develop dementia — and they often turn to unproven ways to try to better their odds, a new study suggests. In a survey, researchers found that almost half of Americans in their 50s and 60s believed they were at least “somewhat likely” to develop dementia. Yet few — 5% — said they had talked to their doctor about ways to lower their risk. Instead, one-third or more were taking fish oil, vitamin E or other supplements to help ward off memory decline — even though none have been proven to have such benefits. “It certainly seems like people believe that supplements or fish oil help preserve their memory,” said lead researcher Dr. Donovan Maust, a geriatric psychiatrist at the University of Michigan, in Ann Arbor. Maust said that might reflect “excitement” over initial research suggesting that certain supplements might ward off memory decline — excitement that wasn’t tempered when later studies failed to show benefits. The findings, published online Nov. 15 in JAMA Neurology, are based on 1,019 adults aged 50 to 64 who were surveyed in 2018. They were asked whether they thought they were “somewhat likely,” “very likely” or “unlikely” to develop dementia in their lifetime. Overall, 44% believed they were somewhat likely, while 4% chose the “very likely” option. How accurate were they? It’s hard… read on >
