What is the risk of developing dementia among healthy 70-year-olds? A study published in Demography, determined the probability using data from the nationally representative and longitudinal Aging, Demographics, and Memory Study—a subsample of the Health and Retirement Study. Among 70-year-olds born in 1920, men had a 27 percent chance of developing dementia before death. Among their female counterparts, the probability was an even higher 35 percent.
But there's more. The probability of developing dementia is increasing as mortality rates at older ages decline, allowing more time for dementia to develop. In the 1940 birth cohort, men aged 70 had a 31 percent chance of developing dementia before death, and women 37 percent. For this cohort, the average 70-year-old man could expect to live 1.1 years with dementia, and the average woman 2.0 years.
"These estimates imply a larger need for individuals and families to plan for a life stage with dementia," concludes the study.
