Multiple sclerosis (MS) is a rare neurological disease of the central nervous system in which the immune system attacks the protective sheath covering nerve fibers, causing communicative disruption between the brain and rest of the body.
Signs and symptoms of MS vary on the amount of nerve damage and the nerves that are affected.
- Muscle weakness
- Double vision
- Lhermitte's sign
- Lack of coordination
- Unsteady gait
- Slurred speech
- Fecal incontinence
- Urinary incontinence
The majority of individuals with multiple sclerosis initially face a relapsing-remitting course; this is known as relapsing-remitting multiple sclerosis (RRMS). Those affected typically experience new symptoms that come in relapses, each followed by a period of recovery known as remission. Remissions can last from a few months to even years.
Rarely, MS itself is fatal. Much more commonly, complications that may be caused by the disease, such as pneumonia, urinary tract infections, falls, depression, heart disease, diabetes, and others can lead to death.
