Although MRI is a very useful diagnostic tool, a normal MRI of the brain does not rule out the possibility of MS. About 5 percent of people who are confirmed to have MS do not initially have brain lesions evidenced by MRI.
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.
MRI plays a vital role in how we diagnose and monitor MS. In fact, over 90% of people have their MS diagnosis confirmed by MRI.
The tests could still be inconclusive
Not necessarily. If you have MS, you still might not have tested positive in all the MS tests.
T-2 scans show the total number of old and new lesions in the brain from the onset of MS. New MS lesions appear as bright spots on a T-2 scan. These are also known as hyperintense lesions. Typical lesions that appear on a T-2 scan are oval in shape.
Small Vessel Ischemic Disease
Also called cerebral small vessel disease, this condition can cause disability, abnormal gait, urinary incontinence, and cognitive decline. “On an MRI, the changes that small vessel ischemic disease causes can look like spots that could be mistaken for MS spots,” says Conway.
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.
Here's where MS (typically) starts
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. Spinal cord inflammation, or what's called partial transverse myelitis, is the second most common symptom Shoemaker typically sees.
Some of the most common early signs are: fatigue (a kind of exhaustion which is out of all proportion to the task undertaken) stumbling more than before. unusual feelings in the skin (such as pins and needles or numbness)
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.
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).
There is a new blood test that may monitor multiple sclerosis disease activity better in clinically stable patients. The test is called sNfL (serum neurofilament). It measures the breakdown of a certain part of neurons, which occurs when multiple sclerosis is attacking the nervous system.
Multiple sclerosis usually affects people between the ages of 20 and 50 years, and the average age of onset is approximately 34 years. Multiple sclerosis can affect children and teens (pediatric MS). It has been estimated that 2%-5% of people with MS develop symptoms prior to age 18.
Although MRI is a very useful diagnostic tool, a normal MRI of the brain does not rule out the possibility of MS. About 5 percent of people who are confirmed to have MS do not initially have brain lesions evidenced by MRI.
Some conditions that doctors may commonly misdiagnose as MS include migraine, RIS, spondylopathy, and neuropathy. To accurately diagnose MS, doctors must rule out conditions with similar symptoms and look for signs and symptoms specific to MS. As such, the process of diagnosing MS may be lengthy and complex.
We have sensitive markers but not specific markers to distinguish MS from other diagnoses." "Sometimes, patients who are misdiagnosed with MS are placed on MS therapies that alter or suppress the immune system. This can put patients who don't have MS at a higher risk of side effects, including infection."
Magnetic resonance imaging (MRI)
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.
MRI: This imaging test lets the doctor take a closer look at your brain. They can see changes caused by multiple sclerosis, like signs of inflammation in the deep parts of your brain or spinal cord. Older people or those with high blood pressure and diabetes also can have the same kinds of spots on a brain MRI.
Tiredness is one of the most common symptoms of a flare. You may also experience weakness or malaise (a general overall feeling of sickness). During a flare, fatigue may be caused by cytokines — substances produced by the immune system.
Characteristics of the MS gait pattern
You may walk more slowly, with shorter steps. You may lack in confidence when you walk – leading to hesitation and stumbling. You might feel unsteady when turning or walking. You might find placing your foot on the ground difficult.
You may feel the sensation of your limb being “asleep” with a pins and needles sensation. Numbness of the face, body or extremities (arms and legs) is one of the most common symptoms of MS. It may be the first MS symptom you experienced.
