Multiple sclerosis (MS) is a disease that affects the brain and central nervous system. Symptoms and severity vary depending on the type and amount of damage that occurs. The most common type is relapsing-remitting multiple sclerosis (RRMS), affecting about 85% of those diagnosed.

MS Types

Our nerve fibers help the brain communicate with the rest of the body. They have a protective cover called myelin on them. In MS, the immune system mistakenly attacks the myelin, eventually causing deterioration or permanent nerve damage. Thus, resulting in movement problems, vision disturbances, and other issues. The damage could be in one area or multiple. Damage to nerves can still occur even though there are no symptoms. No two people will have the same experiences. Symptoms experienced:

• Tremor, lack of coordination, or unsteady gait
• Partial or complete loss of vision and pain with eye movement
• Prolonged double vision
• Blurry vision
• Slurred speech
• Fatigue
• Dizziness
• Tingling or pain in parts of your body

Multiple sclerosis types are characterized by disease progression, frequency of relapses (exacerbations), presenting symptoms, and period of remission. The most common are:

• Relapsing-Remitting (RRMS): Clearly defined relapse of symptoms, followed periods where all symptoms go into remission, or just a few. Also, the progression of the disease isn’t typical during remission.
• Secondary-Progressive (SPMS): This type has a steady worsening of neurological function that continues with or without a relapse of symptoms. Some with RRMS will eventually transition to this stage.
• Primary-Progressive (PPMS): PPMS is characterized by gradual worsening symptoms from the beginning, without relapses or remissions.

Relapsing-remitting multiple sclerosis involves many more attacks than the other more progressive types. Brain and inflammatory lesions are also more familiar with RRMS, though disease progression stops during remission.

Modifying the Course of RRMS

Treating RRMS mainly involves using disease-modifying therapies (DMT). Over a dozen are FDA approved to treat MS, and they help reduce the number of attacks and help slow disease progression. DMT’s also decrease the number of brain and spinal cord lesions. As researchers continue to learn about other ways to reduce new lesions and relapses, the course of RRMS is altered.

New RRMS therapies under investigation include medical marijuana, stem cell therapy, lipoic acid, and more. As a clinical research volunteer, you can help change the future for those with multiple sclerosis. ActivMed currently needs participants to join enrolling studies at our Lawrence, MA location for those with relapsing-remitting or secondary-progressive multiple sclerosis.
