What Is Multiple Sclerosis?

Multiple Sclerosis (MS) is a disease where the body's immune system attacks myelin. The myelin sheath is a fatty protective covering that surround the nerve fibers in the central nervous system. The central nervous system (CNS) is made up of the brain and spinal cord. When the sheath is damaged, it disrupts communication between the brain and the rest of the body. Causes of multiple sclerosis are still unknown.

There are four different types of Multiple Sclerosis:

1).  Relapsing Remitting MS (RRMS)
2). Secondary Progressive MS (SPMS)
3). Primary Progressive MS (PPMS)
4). Progressive Relapsing MS (PRMS)



Symptoms of multiple sclerosis vary between patients and which nerves have been damaged. Symptoms may be mild, moderate, or severe. If you are experiencing any of these symptoms, speak with your healthcare provider.

How Has Living With MS Impacted Your Life?

MS has definitely impacted my life in various ways. It has taken my career, running, and my inability to go hiking or walk for long distances. Fatigue is a big deal with MS, so I don’t have the stamina to do many things I did before diagnosis. On the upside, it has given me more patience; it allows me to appreciate the little things in life. It has given me a new family made up of other people with MS.

Statistics & Diagnosis

Diagnosing Multiple Sclerosis can be tricky. There are various lab and physical tests that can be done to diagnose a patient. Magnetic Resonance Imaging (MRI) of the brain and spine are used to check for lesions. Spinal taps or lumbar punctures are used along with MRIs for a more accurate diagnosis.
