Multiple Sclerosis Diagnosis

Diagnosing Multiple Sclerosis can be difficult. The main reason is MS occurs in parts of the body which are quite hard to access; the spinal cord and the brain. Also different areas of the nervous system are affected in different people. Without evidence of certain symptoms and a series of diagnostic tests, a definite Multiple Sclerosis diagnosis cannot be made.

Generally a Neurologist will look for signs and symptoms that are reflective of Multiple Sclerosis. Sadly people may be experiencing MS symptoms for years before they get severe enough to be referred to a Neurologist. When the patient gets to the Neurologist’s office, he/she will do a neurological examination. This exam evaluates eye and face movements, reflexes and strength of the limbs, coordination and sensation. After the Dr. finishes his/her exam, they will then decide if further testing is needed.

When looking for a Multiple Sclerosis diagnosis, most every patient is referred for a Magnetic Resonance Imaging (MRI). A MRI provides imaging of the nervous system. To date, the MRI is the most useful tool in diagnosing Multiple Sclerosis. MS usually produces small areas of scarring or lesions on the brain and/or spinal cord. A MRI is able to show these lesions which are reflective of Multiple Sclerosis.

Another test used for a Multiple Sclerosis Diagnosis is an Evoked Potentials test. In this test there are wires attached to the patient’s scalp, neck and limbs. In this test, the patient’s visual, hearing and feeling pathways are stimulated in order to see how quickly and efficiently nerve signals reach the brain.

The third test normally used for a Multiple Sclerosis Diagnosis is a Spinal Fluid Examination, perhaps more commonly known as a spinal tap. This test is done to check for proteins called immunoglobulins. A high level of these proteins in the spinal fluid indicates MS.

These are the usually the tests used when looking for a Multiple Sclerosis Diagnosis. Sometimes a CT Scan may be ordered, which is another way to take a look at the brain. To make a Multiple Sclerosis diagnosis, the Neurologist will take all the results of the tests into consideration and then make a decision.
