Neurological examination shows how well your nervous system functioning. Neurologist will examine the abnormality that occurs in the groove nerves that carry messages from the brain to other parts of your body. They will pay attention to changes in eye movement, body balance coordination, weakness, balance, feeling (sense of touch), speech, and reflexes.
This examination may also uncover symptoms that refer to the disease MS, but it can not be used to determine what is causing the symptoms are there. History should disregard other conditions that may show the same symptoms as MS.
Testing by using the tool Visual, Auditory and somatosensory Evoked Potentials (VEP, AEP and SEP)
Although the name is difficult to pronounce, the primacy of these tests is its directness. These tests measure the speed of travel messages from the brain to the nerves.
Free messages through the nervous system is measured by placing small electrodes on the head. It monitor brain waves response to visual stimuli and audio (hearing) or to sensory stimuli. It is very helpful of the three tests is the visual potential although nowadays, along with the increasing use of MRI, these tests are not so often longer needed. Tests VEP AEP and SEP are not invasive or painful and does not require hospitalization at the hospital.
The time it takes nerve to convey messages from the brain is an indicator of the condition of the nervous system and is used to determine whether there demyelinating incurred.
Magnetic Resonance Imaging (MRI)
The MRI scanner is the latest diagnostic tools and provides a detailed overview of ‘slices’ of the brain and spinal cord. It showing the areas of the lesions (lesions or plaques) that may exist.
During scanning with MRI, people who undergo the examination should lay motionless on a table that is inserted into the large tube which is part of the machine that contains the magnet. The person conducting the examination to sit in a different room while watching the image receiving apparatus; but they can see patients who are undergoing examination, usually through a large window.
MRI examination is not painful, but many people feel a very unusual experience. It can be a fear of the dark narrow places (claustrophobia) or feel noisy / rowdy. All these inconveniences can be reduced with sedation. Sometimes done anyway injection of gadolinium-containing contrast material into a blood vessel which can highlight all the areas of inflammation and to assist with diagnosis.
It is important to remember that the person doing the testing are not always able to provide feedback directly to you and your scanned image will be sent to your doctor for analysis.
Although this test is the only test tool that can show lesions in MS. The test results can not be considered a conclusive result. The scanner may not be able to map all lesions, particularly in diseases at an early stage, and some other conditions can produce similar changes in the nervous system.
MRI shows the size, quantity and distribution of lesions, supported by evidence from medical history and neurological examination. It becomes a very significant indicator to confirm the diagnosis of MS. It shows more than 95% abnormality with certain clinical diagnosis. MRI is a very useful tool in clinical trials to test the reliability of these new therapies, associated with the therapy’s ability to demonstrate changes in disease activity.
There are several tests that can be performed with liquid spinal marrow (liquid flowing in the brain and spinal cord), but associated with the disease MS, examined were the patterns formed by proteins.
This fluid is taken from the spinal cord by inserting a needle in the lower back. To numb the skin then given a local anesthetic, and therefore whilst it is uncomfortable it is not usually painful.
This inspection requires people to undergo testing to lay flat for some time after take sample. It may be caused headaches as a side effect of lack of fluids. These side effects can be reduced by drinking soon after being examined. It help the body replace fluids spinal cord was missing. Some people needed treatment in hospital and require a longer time for healing.
Protein in bone marrow fluid behind the majority (90%) patients with MS form a particular pattern when electrified. This procedure can potentially confirm the diagnosis of MS. However, liquid protein spinal cord in MS patients with early-stage or mild MS do not always show the same pattern, thus the result is again uncertain. Frequent MRI results is uncertain.
