MS can occur at any age, but onset usually occurs around 20 and 40 years of age. However, younger and older people can be affected.
Contents. You may have to adapt your daily life if you're diagnosed with multiple sclerosis (MS), but with the right care and support many people can lead long, active and healthy lives.
Factors that may trigger MS include: Exposure to certain viruses or bacteria: Some research suggests that being exposed to certain infections (such as Epstein-Barr virus) can trigger MS later in life. Where you live: Your environment may play a role in your risk for developing MS.
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.
Four disease courses have been identified in multiple sclerosis: clinically isolated syndrome (CIS), relapsing-remitting MS (RRMS), primary progressive MS (PPMS) and secondary progressive MS (SPMS).
There is no cure for multiple sclerosis. Treatment typically focuses on speeding recovery from attacks, reducing new radiographic and clinical relapses, slowing the progression of the disease, and managing MS symptoms. Some people have such mild symptoms that no treatment is necessary.
After many years (usually decades), many, but not all, people with relapsing remitting MS go on to develop secondary progressive MS. In this type of MS, symptoms gradually worsen over time without obvious attacks. Some people continue to have infrequent relapses during this stage.
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).
These include fibromyalgia and vitamin B12 deficiency, muscular dystrophy (MD), amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease), migraine, hypo-thyroidism, hypertension, Beçhets, Arnold-Chiari deformity, and mitochondrial disorders, although your neurologist can usually rule them out quite easily.
While there is no definitive blood test for MS, blood tests can rule out other conditions that cause symptoms similar to those of MS, including lupus erythematosus, Sjogren's syndrome, vitamin and mineral deficiencies, some infections and rare hereditary diseases.
But studies which have investigated whether stress causes MS have been mixed. Although the person with MS knows from their experience that their MS symptoms started after or alongside a stressful period of time, there is no direct evidence that stress causes MS — although it might trigger it.
But ongoing research shows many reasons could be at play, including your genes, where you live, and even the air you breathe. Though some things, like emotional trauma and infection, can worsen MS symptoms, there is no evidence to suggest that anything you do could cause the disease or stop its natural progress.
Some risk factors for MS include how old you are, your biological sex, your family history and some 'environmental factors'. For example, some common infections, smoking and vitamin D levels might affect the risk of developing MS.
Neuromyelitis optica (NMO) is a rare chronic disease that happens when your immune system attacks specific parts of your central nervous system. Experts previously thought this was a rare type of multiple sclerosis (MS) but now recognize it's a separate condition.
Migraines are one of the most common mimicker diseases that can be misdiagnosed for MS. Migraine causes intense throbbing headaches, light sensitivity, and nausea. Many migraine sufferers have also experienced blurred vision similar to the kind caused by optic neuritis in MS patients.
Some people are told they have benign MS. The term benign MS is sometimes used to describe a version of relapsing remitting MS with very mild or no attacks separated by long periods with no symptoms.
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.
Therefore a careful combination of clinical examinations, MRI scans and lumbar punctures are required. To differentiate MS from other similar neurological conditions, most neurologists use what is called the McDonald criteria.
Multiple sclerosis (MS) is a disease of the central nervous system that can affect the brain, spinal cord and optic nerves.
A person will only receive a diagnosis of benign MS if they have been without severe disabling symptoms of the disease for 15 years. However, this does not mean that a person cannot experience a relapse after this time and see their disease progress into a more severe form.
