Racial predilection in multiple sclerosis.

M Alter, M Harshe

    Journal of Neurology
    |August 4, 1975
    PubMed
    Summary
    This summary is machine-generated.

    Environmental factors, not race alone, influence multiple sclerosis risk. Migrants adopt the risk of their new environment, suggesting external influences on this neurological disease.

    Area of Science:

    • Neurology
    • Epidemiology
    • Environmental Health

    Background:

    • Multiple sclerosis (MS) prevalence varies geographically.
    • Existing theories suggest racial or genetic factors contribute to MS risk.

    Purpose of the Study:

    • To investigate the interplay between race, geography, and multiple sclerosis (MS) prevalence.
    • To determine if race or environment is a stronger predictor of MS risk.

    Main Methods:

    • Comparative analysis of MS geographic distribution with racial group habitats.
    • Examination of MS prevalence in racially similar and dissimilar populations across different latitudes.
    • Assessment of MS risk changes in migrants based on age at migration.

    Main Results:

    Related Experiment Videos

    • Racial factors alone do not explain latitudinal MS prevalence patterns.
    • Geographically distinct, racially similar groups exhibit varying MS frequencies.
    • Racially different groups in the same locale show similar MS prevalence rates.
    • Early-life migrants adopt the MS risk profile of their new environment.

    Conclusions:

    • Environmental factors, independent of race, significantly influence MS risk.
    • Genetic factors (e.g., HL-A antigens, immunoglobulin types, pigmentation) may interact with environmental influences.
    • Further research is needed to identify specific environmental triggers and elucidate the mechanisms of genetic influence on MS risk.
