Early, low-cost detection and support for dementia in community settings

Background

Dementia affects tens of millions of people and most live in low- and middle-income countries (WHO). Diagnosis is late, specialist access is scarce, and caregivers lack support tools suited to their language and setting.

Who is affected

Older adults, family caregivers, primary health workers

Existing approaches

Cognitive screening questionnaires, imaging and biomarkers (specialist, costly), caregiver training programmes, reminder and safety devices.

Their limitations

Cultural and language validity of screens; cost of biomarkers; stigma; devices designed for other markets.

Desired outcome

Culturally adapted, low-cost screening and caregiver-support tools that work in community health settings in Indian languages.

Success criteria

Validated against standard assessments; usable by community health workers; measured caregiver-burden change.
