Multiple sclerosis (MS) is a disease of the central nervous system that can affect the brain, spinal cord and optic nerves. Common symptoms include fatigue, bladder and bowel problems, sexual problems, pain, cognitive and mood changes such as depression, muscular changes and visual changes.
Fatigue. Occurs in about 80% of people, can significantly interfere with the ability to function at home and work, and may be the most prominent symptom in a person who otherwise has minimal activity limitations.
How long can MS go undiagnosed? MS is usually diagnosed between the ages of 20 and 50, but it can go undetected for years. In fact, a 2021 study suggested that many people with MS experience disease symptoms several years before being officially diagnosed with the disease.
The early stages of MS - and finding out if, indeed, you do have MS - can be a worrying time. The process of diagnosis can take months, in some cases years, and is often referred to as 'limboland'.
While there are no definitive blood tests for diagnosing MS, they can rule out other conditions that may mimic MS symptoms, including Lyme disease, collagen-vascular diseases, rare hereditary disorders, and acquired immune deficiency syndrome (AIDS).
The early signs and symptoms of MS can be the same for women and men. One of the more obvious first signs of MS is a problem with vision, known as optic neuritis. This is often because it's a more concrete symptom as opposed to vaguer neurological symptoms like numbness and tingling.
Early MS symptoms may include blurred vision, numbness, dizziness, muscle weakness, and coordination issues. MS is progressive and can worsen over time. Eventually, the disease can do damage directly to the nerves, causing permanent disability.
MS can appear at any age but most commonly manifests between the ages of 20 and 40. It affects women two to three times as often as men. Almost one million people in the United States have MS, making it one of the most common causes of neurological disability among young adults in North America.
There is a long list of possible MS symptoms, and they vary from person to person. The most common symptoms of MS include fatigue, urinary and bowel issues and sexual dysfunction. Some patients may have problems with pain, walking, balance, blurred vision, slurred speech and swallowing.
Most symptoms develop abruptly, within hours or days. These attacks or relapses of MS typically reach their peak within a few days at most and then resolve slowly over the next several days or weeks so that a typical relapse will be symptomatic for about eight weeks from onset to recovery.
In most people with relapsing-remitting MS , the diagnosis is straightforward and based on a pattern of symptoms consistent with the disease and confirmed by brain imaging scans, such as an MRI. Diagnosing MS can be more difficult in people with unusual symptoms or progressive disease.
Multiple sclerosis (MS).
When your optometrist detects optic nerve inflammation, that can indicate a diagnosis of MS. Patients with MS often also have double vision, blurred vision, or report pain when moving their eyes.
While constipation is the most common pattern of bowel dysfunction in people with MS, the opposite can also be true and bowel function can actually “speed up”, causing loose stools, diarrhea, and incontinence. Sometimes, loose stools are caused by foods in your diet.
Unhealthy Habits
Smoking and alcohol use are modifiable risk factors — they can be altered by personal choice — and are known from large research studies to increase a person's risk of developing MS or of disease progression.
Feelings of shock, denial, fear, anger, anxiety, loneliness, sadness, uncertainty and guilt are all a normal part of coming to terms with a diagnosis of a lifelong condition like MS. You may feel a sense of relief or acceptance, especially if you've spent a long time trying to find out the reason for your symptoms.
There's no single test that can prove you have it. And many conditions have symptoms that seem like those of MS. A neurologist – a doctor who specializes in treating the disease – should be able to help. They'll ask how you're feeling and help you figure out if your symptoms mean you have MS or another problem.
