Neurology in the developing world.

The social and economic impact of neurologic disorders is being increasingly recognized in the developing world. Demographic transition, especially in large Asian populations, has resulted in a significant increase in the elderly population, bringing to the fore neurologic illnesses such as strokes, Alzheimer's disease, and Parkinson's disease. CNS infections such as retroviral diseases, tuberculosis, and malaria still account for high mortality and morbidity. Traumatic brain injury due to traffic accidents takes a high toll of life. Epilepsy continues to be a major health concern with large segments of the developing world's population receiving no treatment. A significant mismatch between the provision of specialized neurologic services and the requirement for them exists, especially in rural areas. Also, health insurance is not available for the majority, with patients having bear the costs themselves, thus limiting the procurement of available healthcare facilities. Neurologic training centers are few and the availability of laboratory facilities and equipment is largely limited to the metropolitan areas. Cultural practices, superstitious beliefs, ignorance, and social stigma may also impede the delivery of neurologic care. Optimizing available human resources, integrating primary, secondary, and tertiary healthcare tiers and making medical treatment more affordable will improve the neurologic care in the developing world.
