One in nine adults aged 45 and older report experiencing subjective cognitive decline (SCD) — that is, a self-reported increase in confusion or memory loss that is getting worse — according to new analysis by the Centers for Disease Control and Prevention (CDC)’s Alzheimer’s Disease and Healthy Aging Program. Combining data from the 2015 and 2016 Behavioral Risk Factor Surveillance System (BRFSS) surveys, the analysis indicates that 11.2 percent of adults reported SCD, half of whom reported their memory issues caused interruptions in everyday life.
Subjective cognitive decline, including memory loss, is typically one of the earliest warning signs of cognitive impairment and Alzheimer's disease, and an increasing body of research (see below) indicates that modifying certain risk factors can reduce the risk of further cognitive decline. Despite the benefits of early detection, the new CDC analysis shows that less than half (55 percent) of individuals with SCD have talked to a health care provider about their cognitive problems.
