Screening for cognitive impairment in those over the age of 65 without symptoms is of unclear benefit versus harm as of 2020. [6] In a large population-based cohort study included 579,710 66-year-old adults who were followed for a total of 3,870,293 person-years (average 6.68 ± 1.33 years per person), subjective cognitive decline was significantly associated with an increased risk of ...
