Some 4% of U.S. adults aged 65 and older say they have been diagnosed with dementia, a rate that reached 13% for those at least 85-years old, according to a report of a national survey released on Thursday.The report issued by the U.S. Centers for Disease Control and Prevention (CDC) was based on the 2022 National Health Interview Survey, a nationally representative sample of U.S. adults aged 18 and older. The survey in 2019 added the option to report dementia, including Alzheimer’s disease, to its questions on doctor-diagnosed health conditions. The CDC said 1.7% of adults ages 65 to 74 reported a dementia diagnosis, a rate that increased with age. For those ages 75 to 84, the reported dementia rate was 5.7%.
