Multiple Sclerosis

Multiple sclerosis (MS) is the most common neurological disorder diagnosed in young adults. It is defined as an immune-mediated, chronic inflammatory disease that affects the central nervous system (CNS), which includes the brain and spinal cord. MS usually begins between the ages of 20 and 50 years and is twice as common in women as in men. It is usually diagnosed by clinical signs and symptoms supported by radiologic and laboratory evidence for an ongoing process with proof of dissemination in time and space. The progress, severity, and specific symptoms of MS are variable and unpredictable. Some patients experience a flare-up of symptoms and then remain symptom-free for months or even years, but others experience a steady progression of the disease.
