Sorry, Boomers, but a new study suggests that memory, reasoning and comprehension can start to slip as early as age 45. “It is widely believed that cognitive ability does not decline before the age of 60. We were able to show robust cognitive decline even in individuals aged 45 to 49 years,” said Singh-Manoux. This finding runs counter to conventional wisdom that mental decline doesn’t begin before 60, the researchers added. “Cognitive function in normal, healthy adults begins to decline earlier than previously thought,” said study author Archana Singh-Manoux. “It is widely believed that cognitive ability does not decline before the age of 60. We were able to show robust cognitive decline even in individuals aged 45 to 49 years,” added Singh-Manoux, research director at INSERM’s Center for Research in Epidemiology & Population Health at the Paul-Brousse Hospital in Paris. These findings should be put in context of the link between cognitive function and the dementia, Singh-Manoux said. “Previous research shows small differences in cognitive performance in earlier life to predict larger differences in risk of dementia in later life,” she said. Understanding cognitive aging might enable early identification of those at risk for dementia, Singh-Manoux said. The report was published in the Jan. 5 issue of BMJ.
