Summary
Multiple Sclerosis (MS) in India shows similar progression and affected areas as in the US, but with more frequent visual system involvement. Indian patients lacked family history, suggesting environmental factors may trigger MS.
Area of Science:
- Neuroscience
- Epidemiology
- Immunology
Background:
- Multiple Sclerosis (MS) prevalence is notably lower in India compared to Western countries.
- Clinical manifestations and disease characteristics of MS in India remain largely uncharacterized.
- Understanding geographical variations in MS is crucial for disease management and research.
Purpose of the Study:
- To compare the clinical and paraclinical features of Multiple Sclerosis (MS) between Indian and United States populations.
- To identify similarities and differences in disease progression and affected neurological systems.
- To investigate potential etiological factors, including genetic and environmental influences, in Indian MS patients.
Main Methods:
- A case-control study design was employed to compare MS patients from India and the United States.
- Assessment included clinical evaluations, evoked potential tests, and Magnetic Resonance Imaging (MRI) criteria.
- Data on disease progression, lesion distribution, and family history were systematically collected and analyzed.
Main Results:
- Disease progression rates and the frequency of central nervous system involvement (cerebral hemispheres, cerebellum, spinal cord, brainstem) were comparable between the two populations.
- Indian MS patients exhibited a higher incidence of visual system involvement compared to their US counterparts.
- A significant finding was the absence of a family history of MS among all Indian patients studied.
Conclusions:
- Multiple Sclerosis (MS) in India shares core pathological and progression characteristics with the disease in the United States.
- The increased visual system involvement in Indian patients warrants further investigation.
- The lack of familial aggregation suggests a strong role for environmental factors in triggering MS in the Indian population.
