Concerning multiple sclerosis (MS), which of the following is NOT correct

  • A. Some HLA alleles confer susceptibility to MS
  • B. A gender bias is observed with females more at risk for MS than males
  • C. Exhibits a North-South gradient, with a higher incidence reported for populations living above the equator
  • D. Affects mostly individuals over 65 yrs. of age
Correct Answer: D

Rationale: The correct answer is D because multiple sclerosis (MS) typically affects individuals between 20-50 years old, with the most common age of onset being between 20-40 years. MS is not primarily a disease of older individuals over 65 years. Choices A, B, and C are incorrect because various HLA alleles have been associated with MS susceptibility, females are indeed more at risk for MS than males, and there is a known North-South gradient in MS incidence, with higher rates reported for populations living farther from the equator.
