India Faces Dementia Crisis as New Care Framework Targets Biological Mechanisms

India faces an impending dementia crisis as demographic aging accelerates, positioning the country for one of the largest absolute increases in dementia cases worldwide. This comprehensive review addresses the urgent need for integrated care models that bridge biological understanding with practical interventions.

The research examines the complex biological mechanisms underlying dementia, including amyloid-β and tau pathology, mitochondrial dysfunction, neuroinflammation, and loss of proteostasis. Systemic factors such as metabolic dysregulation, gut-brain axis disruption, and chronic inflammation further amplify neurodegeneration risk.

Key modifiable risk factors identified include sleep deprivation, which accelerates amyloid deposition and brain atrophy, plus comorbid conditions like diabetes and cardiovascular disease. The authors highlight promising prevention strategies including physical activity, healthy diet, sleep optimization, and emerging psychedelic-assisted interventions.

The proposed solution involves establishing a tiered network of dementia centers across India, integrating mechanistic knowledge with community-based care, early detection protocols, and culturally tailored interventions. Private hospitals like Apollo Research Academy represent opportunities for implementation.

This framework emphasizes prevention across the lifespan, equitable access, and sustainable implementation. The approach aligns biological insights with policy innovation to address India's growing dementia burden while safeguarding cognitive health in the aging population.
