Tau Ming Liew, King Fan Yip, Kaavya Narasimhalu, Simon Kang Seng Ting, Weishan Li, Sze Yan Tay, Way Inn Koay. JMIR Aging, 2025-11-14
Topic: Risk, prevention and care in population studies
This ultra-brief questionnaire enables rapid screening for cognitive impairment (in <1 min) by family members or as part of community geriatric assessments. Its excellent performance across literacy levels supports its utility for case finding in diverse populations, including underserved communities and lower- and middle-income countries.

Key findings
- This ultra-brief questionnaire enables rapid screening for cognitive impairment (in <1 min) by family members or as part of community geriatric assessments.
- Its excellent performance across literacy levels supports its utility for case finding in diverse populations, including underserved communities and lower- and middle-income countries.
Why it matters
This study found that an ultra-brief informant questionnaire enables rapid screening for cognitive impairment in under one minute and performed well across literacy levels. It is a case-finding tool for diverse populations and does not treat, cure or prevent Alzheimer's disease.
