Multiple sclerosis, or MS, is a chronic disorder affecting the nervous and immune system.
When someone has MS, their immune system mistakenly attacks healthy tissues within their central nervous system. Specifically, MS causes inflammation and damage to tissues called the myelin sheaths, which surrounds nerve fibers and acts as insulation to help signals and information move about the brain and spinal cord.
MS can impact multiple parts of the central nervous system, so signs and symptoms vary widely. Common symptoms include:
- Blurry vision
- Numbness and tingling
- Muscle spasms and Chronic pain
- Gastrointestinal problems, including bladder issues
- Balance and walking difficulties
- Cognitive issues, including memory loss and depression
