During what age range and gender is the typical onset of Multiple Sclerosis?

The typical onset of Multiple Sclerosis (MS) predominantly occurs in women between the ages of 18 and 45. This demographic is significant because MS is known to have a higher prevalence in females compared to males, with women being diagnosed more often. The age range of 18 to 45 encompasses a critical period when individuals are often in their late teens to early adulthood, aligning with the common age for neurological disorders to manifest.

The choices that include men or differ in age do not reflect the established patterns of MS onset. MS is notably less common in males, particularly in the earlier age brackets, and the older brackets provided do not align with the statistical evidence regarding the disease's prevalence and demographics. As such, the identification of young women as the primary demographic for MS onset is supported by clinical research and epidemiological data.
