MS occurs when the immune system attacks nerve fibers and myelin sheathing (a fatty substance which surrounds/insulates healthy nerve fibers) in the brain and spinal cord. This attack causes inflammation, which destroys nerve cell processes and myelin – altering electrical messages in the brain.
What part of the body does MS affect first?
Visual problems are often the first symptoms associated with MS. The optic (eye) nerve can become inflamed (optic neuritis) as the optic nerve is a common area where damage to the protective covering of nerves (demyelination) occurs. More than half of people with MS will experience at least one issue with vision.
What part of the body does MS affect the most?
Multiple sclerosis (MS) is a potentially disabling disease of the brain and spinal cord (central nervous system). In MS , the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body.
Where do MS lesions start?
Signs and Symptoms Characteristic lesions are located in the periventricular and juxtacortical regions, in addition to the brainstem, cerebellum, spinal cord, and optic nerve.

What triggers MS to start?
Multiple sclerosis is caused by your immune system mistakenly attacking the brain and nerves. It’s not clear why this happens but it may be a combination of genetic and environmental factors.
Does MS show up in blood work?
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 erythematosis, Sjogren’s, vitamin and mineral deficiencies, some infections, and rare hereditary diseases.
What age does MS typically start?
How do they check if you have MS?
There are no specific tests for MS . Instead, a diagnosis of multiple sclerosis often relies on ruling out other conditions that might produce similar signs and symptoms, known as a differential diagnosis. Your doctor is likely to start with a thorough medical history and examination.
What is the number 1 cause of MS?
Boston, MA – Multiple sclerosis (MS), a progressive disease that affects 2.8 million people worldwide and for which there is no definitive cure, is likely caused by infection with the Epstein-Barr virus (EBV), according to a study led by Harvard T.H. Chan School of Public Health researchers.
When should you suspect multiple sclerosis?
People should consider the diagnosis of MS if they have one or more of these symptoms: vision loss in one or both eyes. acute paralysis in the legs or along one side of the body. acute numbness and tingling in a limb.
Does an MRI always show MS?
MRI is considered the best test to help diagnose MS. However, 5% of people with MS do not have abnormalities detected on MRI; thus, a “negative” scan does not completely rule out MS. In addition, some common changes of aging may look like MS on a MRI. To track the progress of disease.
Does MRI show early MS?
MRI scans are an important way to help health care providers figure out if a person has MS or not, but MRI scans cannot diagnose MS by themselves. While it is true that almost all people with MS will have lesions on MRI, not all people with MRI lesions have MS.
Where is the pain in MS?
Tightness or stiffness of the muscles, called spasticity, is caused directly by MS. Spasticity, will alter walking and cause pulling on the joints. This can result in pain typically in the ankles, knees, hips and back.
What are three symptoms that people with multiple sclerosis are likely to experience?
Early symptoms can include vision problems, trouble walking, and tingling feelings. MS affects people differently. But common problems are trouble with movement and thinking, and bowel and bladder incontinence.
How does an MS flare start?
Flare-ups happen when inflammation in your nervous system damages the layer that covers and protects nerve cells. This slows or stops nerve cell signals from getting to the parts of your body where they need to go.
What does MS inflammation feel like?
These are painful sensations that can affect the legs, feet, arms and hands and feel like burning, prickling, stabbing, ice cold or electrical sensations. They can interfere with daily activities, sleep and overall quality of life. Pruritis (itching) is a form of dysesthesias and may occur as a symptom of MS.
What is the first stage of MS?
Clinically isolated syndrome describes a person’s first episode of neurological symptoms caused by damaged myelin in the CNS. CIS is often referred to as the first stage of MS, even though it doesn’t meet the MS criterion for dissemination in time (MS damage that occurs on different dates).
What part of the body does MS affect first?

What are three possible causes of MS?
Experts aren’t exactly sure what causes multiple sclerosis (MS). They have identified four primary risk factors for the condition: immune system, genetics, environment, and infection. Other risk factors for MS range from smoking to having obesity.
