your genes – MS isn't directly inherited, but people who are related to someone with the condition are more likely to develop it; the chance of a sibling or child of someone with MS also developing it is estimated to be around 2 to 3 in 100.
MS is not directly inherited from parent to child. There's no single gene that causes it. Over 200 genes might affect your chances of getting MS.
The cause of multiple sclerosis is unknown. It's considered an immune mediated disease in which the body's immune system attacks its own tissues. In the case of MS , this immune system malfunction destroys the fatty substance that coats and protects nerve fibers in the brain and spinal cord (myelin).
Several studies have shown that obesity in childhood and adolescence, particularly in girls, increased the risk of later developing MS. Other studies have shown that obesity in early adulthood may also contribute to an increased risk of developing MS.
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.
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.
What Does MS Feels Like? A lack of feeling or a pins-and-needles sensation can be the first sign of nerve damage from MS. It usually happens in your face, arms, or legs, and on one side of your body. It tends to go away on its own.
Blood Tests: Currently, there are no definitive blood tests for diagnosing MS, but they can be used to rule out other conditions that may mimic MS symptoms, including Lyme disease, collagen-vascular diseases, rare hereditary disorders and acquired immune deficiency syndrome (AIDS).
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. Resolution is often complete.
The prevalence of MS in Australia has increased from 103.7 per 100,000 people in 2017 to 131.1 per 100,000 people in 2021. This increase in prevalence is most likely due to changes in exposure to known MS risk factors.
We know early treatment improves long-term health and wellbeing by slowing down the build up of irreversible damage and reducing the number of relapses people experience. Starting MS treatment early is best but if you start later it can also have some benefits.
An MRI scanner uses a strong magnetic field to create a detailed image of inside your brain and spinal cord. It's very accurate and can pinpoint the exact location and size of any inflammation, damage or scarring (lesions). MRI scans confirm a diagnosis in over 90 per cent of people with MS.
Can stress cause MS? Some people with MS feel that they developed MS as a direct result of some stressful event or trauma. The evidence on this connection is mixed. Some studies do see an effect whilst others don't.
Numbness of the face, body, or extremities (arms and legs) is often the first symptom experienced by those eventually diagnosed as having MS.
Abnormal sensations can be a common initial symptom of MS. This often takes the form of numbness or tingling in different parts of your body, such as the arms, legs or trunk, which typically spreads out over a few days.
Your neurologist will look for abnormalities, changes or weakness in your vision, eye movements, hand or leg strength, balance and co-ordination, speech and reflexes. These may show whether your nerves are damaged in a way that might suggest MS.
They will examine you to check how different parts of your nervous system are working. A combination of tests is used to diagnose MS. The best test is an MRI of your brain and spinal cord to detect areas of damage. You might also need to have blood tests, a lumbar puncture and tests to measure nerve activity.
Foot drop, or dropped foot, is a symptom of multiple sclerosis caused by weakness in the ankle or disruption in the nerve pathway between the legs and the brain. This disruption means it is difficult to lift the front of the foot to the correct angle during walking.
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.
Overview. Dizziness is a common symptom of MS. People with MS may feel off balance or lightheaded. Much less often, they have the sensation that they or their surroundings are spinning — a condition known as vertigo.
