text: Screening Screening for cognitive impairment in those over the age of 65 without symptoms is of unclear benefit versus harm as of 2020. 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 subsequent dementia.
  In addition to a series of cognitive tests, general practitioner physicians often also rely on clinical judgement for diagnosing cognitive impairments. Clinical judgement is ideal when paired with additional tests to that permit the medical professional to confirm the diagnosis or confirm the absence of a diagnosis. Clinical judgement in these cases may also help inform the choice in additional tests.
  Treatment
  Deciding on an appropriate treatment for people with cognitive decline takes clinical judgement based on the diagnosis (the specific cognitive problem), the person's symptoms, other patient factors included expectations and the person's own ideas, and previous approaches to helping the person.
  Other findings
  Although one would expect cognitive decline to have major effects on job performance, it seems that there is little to no correlation of health with job performance.  With the exception of cognitive-dependent jobs such as air-traffic controller, professional athlete, or other elite jobs, age does not seem to impact one's job performance. This obviously conflicts with cognitive tests given, so the matter has been researched further.
