We read the article entitled “Major neurological disorders in tribal areas of Himachal Pradesh: A community-based survey” in the esteemed Indian Journal of Health Sciences and Biomedical Research KLEU with great interest. Bhardwaj et al. estimated the proportion of the tribal population of Himachal Pradesh affected by some neurological diseases. A community-based survey and a cluster-randomized sampling technique were used to study 10,000 individuals between 2017 and 2018. They concluded that the prevalence of neurological diseases in tribal populations is similar to the general population.
Neurological disorders are the leading cause of disability (250.7 million disability-adjusted life years) and the second leading cause of death (9.4 million) worldwide. Furthermore, in the last three decades, the absolute number of deaths increased by almost 40% and the disability-adjusted life years increased more than 15%, despite declines in communicable neurological disorders such as tetanus, meningitis, and encephalitis.
We provide [Table 1] to better discuss the data found in the study by Bhardwaj et al. and the burden of neurological disorders worldwide. The population analyzed was from the United States, India, and Himachal Pradesh (tribal population from India).,, We included data about the prevalence of migraine, stroke, epilepsy, dementia, and parkinsonism. The spreadsheet provided by the India State-Level Disease Burden Initiative Neurological Disorders Collaborators was reanalyzed.
The order of frequency of neurological disorders among the populations studied was the same, with migraine being the most common and parkinsonism being the rarest. However, the US population was the most frequently affected by neurological disorders, especially in the case of cerebrovascular accidents and migraine (US 68.48% vs. India 35.06%).
Apparently, neurological diseases increased especially in low- and middle-income countries in the past years. This may suggest that advances in the prevention, management, and care of common neurological disorders are not being sufficiently effective to the demands related to global demographic changes throughout the last decade. Moreover, the study in Himachal Pradesh indicates that diseases related to lifestyle factors are possibly substantially affecting the indigenous population as a result of globalization.
In the Policy View by Feigin et al., a policy-making summary of the identified priorities and flexible recommendations related to major neurological disorders is provided. Interestingly, they recommend that governments should develop and implement methods to better control well-known risk factors for common neurological diseases such as taxation strategies to mitigate unhealthy behaviors. Furthermore, a preventive strategic system for neurological diseases should be promptly combined with primary and secondary prevention strategies for noncommunicable diseases such as cancer, cardiovascular diseases, chronic kidney disease, and diabetes.
The burden of neurological disorders in India and globally is likely to rise owing to population growth and aging, independently of the population being studied. The most common neurological diseases are still the same. Therefore, urgent measures to reduce this burden are needed.
