Since diagnosing MS can be very difficult, it must be done by a neurologist who specializes in treating MS. As many as 10 percent of people diagnosed with multiple sclerosis actually have some other condition that mimics MS.
MS is diagnosed by your neurologist. They will use a specific checklist to diagnose MS, known as the McDonald criteria. They'll carry out a number of tests to run through the criteria, which could include blood tests and MRI.
A GP will refer a patient to a neurologist if MS symptoms are present and MS is suspected. It is generally a neurologist who will make the initial diagnosis of MS. Neurologists will develop a treatment plan and prescribe any medication or drug therapy.
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.
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.
Diagnosis and early intervention
As optic neuritis is the presenting sign of MS in up to 30 percent of patients, the eye exam can lead to the initial systemic diagnosis.
Multiple sclerosis is often difficult to diagnose because there is no single test or finding on an exam that makes the diagnosis and because the disorder varies from person to person. In most cases, there is a history of neurological symptoms that come and go over years.
Magnetic resonance imaging (MRI) is the test of choice for diagnosing MS in combination with initial blood tests. MRIs use radio waves and magnetic fields to evaluate the relative water content in tissues of the body. They can detect normal and abnormal tissues and can spot irregularities.
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.
Magnetic resonance imaging, or MRI, is a wonderful tool to help diagnose and follow people with MS. MRI is safe and relatively non-invasive yet can provide very detailed images of the brain and spinal cord that can reveal MS lesions (also known as demyelination, spots, or plaques) and changes in MS activity over time.
Here's where MS (typically) starts
Optic neuritis, or inflammation of the optic nerve, is usually the most common, Shoemaker says. You may experience eye pain, blurred vision and headache. It often occurs on one side and can eventually lead to partial or total vision loss.
Vision Problems
The first symptom of MS for many people. Optic neuritis, neuromyelitis optica, blurred vision, poor contrast or color vision, and pain on eye movement can be frightening — and should be evaluated promptly.
Numbness or Tingling
A lack of feeling or a pins-and-needles sensation can be the first sign of the nerve damage from MS. It usually happens in the face, arms, or legs, and on one side of the body. It also tends to go away on its own.
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.
The first step in diagnosing MS is taking a thorough medical history. Your doctor will ask you about your symptoms, including when they began and whether you've noticed any patterns or triggers. They may also ask you about: injuries, diseases, or other health conditions with which you've been diagnosed.
MS is best detected by a neurological examination and painless imaging studies of the brain and spinal cord using magnetic resonance testing (MRI). An ophthalmologist also can use a test called an optical coherence tomography (OCT) to determine if the optic nerve has been affected by MS.
That said, certain symptoms should prompt you to seek help. If you're experiencing blurred vision, numbness, weakness or dizziness at the same time and for more than a day, those symptoms could be potential early signs of MS. It's important not to let too much time slip by before seeing a doctor.
Over 25,600 people in Australia are living with multiple sclerosis, including 3,700 Queenslanders, and it affects each person differently. On average more than 10 Australians are diagnosed with MS every week.
And if left untreated, MS can result in more nerve damage and an increase in symptoms. Starting treatment soon after you're diagnosed and sticking with it may also help delay the potential progression from relapsing-remitting MS (RRMS) to secondary-progressive MS (SPMS).
A common visual symptom of MS is optic neuritis — inflammation of the optic (vision) nerve. Optic neuritis usually occurs in one eye and may cause aching pain with eye movement, blurred vision, dim vision, or loss of color vision. For example, the color red may appear washed out or gray.
Floaters are a common ocular symptom for individuals with multiple sclerosis, but MS isn't a leading cause. On their own, floaters don't usually indicate serious conditions. Eye conditions like optic neuritis can be an early warning sign of oncoming multiple sclerosis.
The two most common eye movement problems in MS are double vision (diplopia) and involuntary eye movements (nystagmus).
