India presents a unique epidemiological challenge:
- World's most populous nation (1.4+ billion)
- Rapid demographic transition: aging population growing rapidly
- Significant regional variation in demographics and healthcare access
- Historically underrecognized neurodegenerative diseases
- Emerging research infrastructure but limited data

| Total (60+) |
~5-7% |
~8-10 million |
| Total (all ages) |
~0.6-0.8% |
~8-10 million |
Key Characteristics:
- Lower reported prevalence than Western countries (possible underdiagnosis)
- Rural prevalence may be higher than urban (less diagnosis)
- Significant variation by region (South India better studied)
- Strong family-based care reducing institutional recognition

Critical Note: India will have the second-highest dementia burden globally after China by 2040.
- South India (Karnataka, Tamil Nadu, Kerala): Most data available; higher reported prevalence
- North India (Delhi, Punjab, UP): Limited studies; likely underreported
- West India (Maharashtra, Gujarat): Moderate data
- Rural areas: Higher age-standardized rates; less healthcare access

- Neurologists: ~3,000 total (1 per 500,000 population)
- Memory clinics: <100 nationwide (mostly in metro cities)
- Dementia care facilities: <50 specialized facilities
- Diagnostic capacity: Very limited in rural areas
- Awareness: Low recognition of dementia as disease
- Stigma: Mental illness stigma affecting reporting
- Access: 70% population in rural areas with limited specialists
- Cost: Out-of-pocket expenses; no universal coverage for dementia
- Infrastructure: Limited neuroimaging, biomarker testing
- Ayurveda: Used extensively for cognitive symptoms
- Yoga: Complementary therapy for movement in PD
- Traditional practitioners: Often first point of contact
- Need for integration with modern neurology
- Dementia India Report: Advocacy and awareness
- National Programme for Healthcare of Elderly: Includes cognitive decline
- State-level initiatives: Some states have dementia programs
- Research funding: Increasing but still limited
