FRIDAY, July 13, 2018 (HealthDay News) -- More than 11 percent of adults aged ≥45 years in the United States report subjective cognitive decline (SCD), according to research published in the July 13 issue of the U.S. Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report.

Christopher A. Taylor, Ph.D., from the CDC in Atlanta, and colleagues analyzed combined data from the 2015 and 2016 Behavioral Risk Factor Surveillance System surveys to examine the prevalence of SCD.

The researchers found that 11.2 percent of adults aged ≥45 years reported having SCD, of whom about half (50.6 percent) reported SCD-related functional limitations. SCD was reported by 13.8 percent of persons living alone aged ≥45 years and by 15.2 percent of those with any chronic disease.

"Adults should discuss confusion or memory loss with a health care professional who can assess cognitive decline and address possible treatments and issues related to chronic disease management, medical care, and caregiving," the authors write.
