There is insufficient evidence to determine if screening for dementia
in older adults is warranted, according to the latest report from the US Preventive
Services Task Force.
The task force found that although some evidence suggests that screening
successfully detects dementia, the age and education of the patient can cause
misleading results. In addition, with few treatments available, there is no
evidence that early detection results in better outcomes. The task force was
also concerned about the lack of evidence regarding possible harms from screening,
including anxiety, depression, and social stigma.
