The figures are alarming, especially given that, in addition to however many people will get dementia, another significant portion of people will experience cognitive decline that is not diagnosable as dementia but which will still be problematic in various ways.<\/p>\n<p>Below are a few quotes from the paper:<\/p>\n<p>\u201cIn the present study, our primary objective was to generate contemporary estimates of the lifetime risk of dementia, overall and across different population subgroups. We also characterized differences in the age of diagnosis and projected the number of new dementia cases that will develop in the United States over the next four decades. To achieve these aims, we analyzed over three decades of longitudinal data (1987\u20132020) from participants in the Atherosclerosis Risk in Communities (ARIC) study.\u201d<\/p>\n<p>\u201cIn this large community-based cohort study, 42% of participants developed dementia after midlife.\u201d<\/p>\n<p>\u201cThe median age of dementia diagnosis was 81 years (interquartile range: 77\u201386 years).\u201d<\/p>\n<p>\u201cOur lifetime risk estimates are higher than those in previous population-based studies. In the Framingham Heart Study, 14% of men and 23% of women developed dementia from age 45\u2013105 years. The lifetime risk of dementia (age 45\u201395 years) in the Rotterdam Study was 19% and 31% for men and women, respectively. The higher lifetime risk estimates in our analyses may reflect differences in dementia ascertainment. Previous research primarily relied on cognitive testing at study visits and a review of medical and death records to identify dementia. However, this may result in under-detection, because participants with cognitive impairment are less likely to attend in-person assessments, and administrative records lack sensitivity. In contrast, the ARIC study combined cognitive evaluations at study visits with intensive surveillance (phone interviews and review of hospital and death records) to maximize dementia ascertainment. Ongoing phone interviews with participants and informants were especially important, as they identified approximately half of all dementia cases in our study.\u201d<\/p>\n<p>\u201cPolicies focused on optimizing cardiovascular health and preserving hearing may be particularly important. Accumulating data from clinical trials have linked healthy lifestyle behaviors, the absence of vascular risk factors and hearing rehabilitation with improved cognitive outcomes. However, only approximately 20% of US adults are meeting recommended lifestyle and cardiovascular health targets, and only approximately 30% of older adults with hearing loss are using a hearing aid.\u201d<\/p>\n<h3>Other Recommended Reading<\/h3>\n<p>Thanks for reading!<\/p>\n<\/div>\n<p style=\"display: inline;\">\n<p>&#8220;A wonderful book that tells its readers, with simple logical explanations, our Boglehead Philosophy for successful investing.&#8221;<br \/>\n&#8211; Taylor Larimore, author of <\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>This week I encountered a new paper that discusses the risk of getting dementia after age 55.
