Neurological diseases contribute substantially to global mortality and disability. Conditions such as stroke, dementia, epilepsy, Parkinson’s disease, and neurodevelopmental disorders collectively represent a major and growing public health challenge, particularly as populations age.

This episode examines:

• The global burden of neurological disease• Stroke epidemiology and vascular risk factors• Dementia and ageing populations• Parkinson’s disease and neurodegeneration• Epilepsy in low- and middle-income settings• Neurodevelopmental disorders and early-life determinants• Environmental and occupational exposures• Access to neurological care and workforce gaps• Long-term disability and caregiver burden

Neurological conditions often involve complex, long-term trajectories requiring coordinated care across health and social systems. Stroke prevention intersects with cardiovascular risk reduction, while dementia prevalence reflects demographic transition and longevity.

The episode highlights both prevention opportunities - including hypertension control and early intervention - and the profound societal implications of neurological disability.

Brain health is shaped by vascular, metabolic, environmental, and social forces across the life course.

Key Takeaways

• Neurological diseases are major contributors to global disability and mortality• Ageing populations are increasing dementia prevalence• Stroke prevention depends on cardiovascular risk management• Epilepsy care gaps remain significant in low-income settings• Early-life conditions influence neurodevelopmental outcomes• Long-term care demands substantial social and economic resources• Brain health is influenced by life-course determinants
