Which statement regarding Multiple Sclerosis is NOT true?

Multiple Sclerosis (MS) is a chronic autoimmune disorder that primarily affects the central nervous system. The statement that MS primarily affects people living in Northern latitudes is indeed true. Geographic studies have shown that the prevalence of MS is higher in populations that are situated farther from the equator. This phenomenon is believed to be linked to factors such as reduced sun exposure leading to lower vitamin D levels.

The correct answer points out the inaccurate statement regarding the characteristics of MS. It typically does affect individuals in the age range of 20 to 40 years, with a significant number being diagnosed in their 30s. Additionally, the condition is more prevalent in females than males, with a reported female-to-male ratio of approximately 3:1. Lastly, to establish a diagnosis of MS, evidence of lesions in the central nervous system is required, along with the criteria of “separation of time and space,” meaning that symptoms or lesions are occurring at different times and in different neurological locations.

Thus, the assertion that MS primarily affects people living in Northern latitudes is a true statement, while the request for a statement that is not true leads to further understanding of correct aspects pertaining to the demographic and diagnostic features of the disease.
