China represents the world's largest population and one of the fastest-aging societies. With over 280 million people aged 60+ and a projected 400+ million by 2050, neurodegenerative diseases represent an emerging public health crisis. Rapid urbanization, environmental factors, and genetic predisposition shape the epidemiological landscape.

Projected Increase: China will have more dementia patients than the entire US population by 2040.
- Eastern provinces (Jiangsu, Zhejiang, Shanghai): Higher prevalence due to aging population
- Northeast (Liaoning, Jilin): Higher rates due to industrial history and older demographics
- Rural areas: Higher age-standardized rates; less healthcare access
- Urban areas: Rising rapidly due to lifestyle factors

Key Challenges:
- Rapidly aging population outpacing healthcare infrastructure
- Geographic disparities in care access
- Limited trained workforce (neurologists, geriatricians)
- Cultural factors affecting diagnosis and care-seeking
- Growing burden on family caregivers
