<div>This systematic review and meta-analysis explores the diagnostic accuracy of self-administered cognitive assessments when used to identify dementia in adults.&nbsp;</div>

Cochrane Collaboration; National Institute for Health and Care Research (United Kingdom)

From database inception to November 2, 2022

<div>Cross-sectional studies with at least 10 participants</div>

11 (3 included in the meta-analysis)

<div>Self-administered cognitive assessments had sensitivity ranging from 55% to 100% and specificity ranging from 45% to 100% when used to identify adults with dementia. Findings for specific tests included:</div> <div> <ul> <li><strong>Test Your Memory&nbsp;</strong>had a pooled sensitivity of 94% and a specificity of 66% when using a cut-off of 42/50 for the English, Norwegian, and Spanish versions of this test. The Greek version had a sensitivity of 81% and specificity of 71% within one study (cut off: 31/50), while the French version had a sensitivity of 93% and specificity of 76% in another study (cut-off: 40/50).</li> <li><strong>The Self-Administered Gerocognitive Exam (SAGE)</strong> had a sensitivity and specificity of 95% in within one study (cut-off: 16/21).</li> <li><strong>The Electronic SAGE (e-SAGE) </strong>had a sensitivity of 95% and a specificity of 100% within one study (cut-off: 14/21).</li> <li><strong>The Clock Completion Test</strong> had a sensitivity of 67% and specificity of 69% within one study (cut-off not reported).</li> <li><strong>The Korean Dementia Screening Questionnaire </strong>had a sensitivity of 73% and specificity of 71% within one study (cut-off: 3).</li> <li><strong>Braincheck Memory&nbsp;</strong>had a sensitivity of 89% and specificity of 78% within one study (cut-off not reported).&nbsp;</li> </ul> <div>Limitations to this review are the limited number of included studies, small sample sizes, heterogeneity between studies, and the lack of investigation into the impact of dementia subtype or severity on diagnostic accuracy. Additional research is warranted.&nbsp;</div> </div>
