Epidemiology of Mild Cognitive Impairment?
-
Annual prevalence estimates for mild cognitive impairment (MCI) range from 12% to 18% in persons older than 60 years, a finding reflected in multiple international studies. Among community-dwelling African Americans, the estimated prevalence is 19.2% for those aged 65–74 years, 27.6% for those aged 75–84 years, and 38% for those aged 85 years and older. The prevalence of mild cognitive impairment increases with age. The prevalence is 10% in those aged 70–79 years and 25% in those aged 80–89 years. Many studies indicate that the risk of Alzheimer disease (AD) is significantly higher in women than in men, and it is therefore presumed that the likelihood of developing MCI is greater in women than in men. Virtually nothing is known about cultural and racial factors influencing the clinical manifestations of MCI.

@pritha According to a large population-based study conducted in 2016, there is no significant link between exposure to general anesthesia and the development of MCI in individuals aged 40 years and older. Anesthesia exposure, assessed as a dichotomous variable, was not associated with MCI nor was there was a link between the number of anesthesia exposures and MCI.
