3. Epidemiology
In the United States, it has been estimated that the prevalence of MS ranges from 58 to 95 per 100,000 individuals. Per the National Multiple Sclerosis Society, as many as 400,000 individuals are affected. However, misdiagnosis is common. MS is more common among women and is usually diagnosed at the ages of 15 to 45 years old.
However, it can occur at any age. Globally, about 2.1 million individuals have MS with lower rates among the Japanese, Chinese, and African blacks while being higher among Palestinians, Sardinians, and Parsis. MS is the commonest immune mediated condition that affects the central nervous system.
