Current approaches to dementia screening and case finding in low ‐ and middle‐income countries: Research update and recommendations

Approximately 47 million people have dementia worldwide, with this figure, it is expected to almost triple by 2050. Most people with dementia (approximately two ‐thirds) live in low‐ and middle‐income countries (LMICs). This presents a significant challenge for such countries that often have limited financial resources and less well‐developed health and social care systems. In the absence of a cure, reducing the future costs of dementia care and bur den of disease may be best achieved by a greater emphasis on (1) more timely diagnosis with earlier intervention to maintain functional independence and (2) undertaking “screening” in groups at high risk of developing dementia, case finding, and using brief cognitive assessment instruments. In c linical settings, a wide range of instruments for dementia screening and diagnosis are currently available; however, few cognitive assessment tools have been developed specifically for clinical use within LMIC settings. Screening for dementia and cognitive impairment in LMICs largely relies on tools adapted from high‐income countries (HICs); these often lack validation in these settings leading to education, literacy, and cultural biases. Research is urgently needed to develop cognitive assessment tools and dementia diagnostic approaches that are appropriate and feasible for clinical use in LMIC settings.
