receive mixed signal from the brain, deeply affecting the muscle. Depending on the affected area of the brain, will then determine the affected parts of the body controlled by that area; for instance vision, hearing, motion, and touch. With different parts of the brain controlling different parts of the body, some areas may be affected more than others causing an imbalance in the body’s homeostasis. In addition, a Neurologist (brain specialist) examines the body symptoms and performs numerous amounts of test to diagnose properly. The common test used to diagnose Multiple Sclerosis is an MRI (Magnetic Resonance Imaging) of the brain, an MRI machine is mainly used to see the soft tissues, organs, and ligaments of the human anatomy at any plane. The MRI scanner is a cylindrical machine that creates a strong magnetic field and sends radio wave signals from the scanner itself to the computer. With the magnetic field surrounding the body, it aligns hydrogen protons in the body along a vector. The computer converts the signals into a film form where the MRI technician can view them and send them to be read by the Radiologist (radiology specialist). A cross-sectional view can be obtained to see if multiple sclerosis can be seen from the opposite side of the brain. At the University of British Columbia researchers have come up with a faster way for MRI machines to detect and clarify the M.S. outbreak. The new machine will not only take the electromagnetic intensity waves like the common used MRI machine, the new one takes the frequency into account as well. A dye or contrast maybe used to highlight the affected organs and is administered by the MRI Technician. Compared to a CAT scanner, the MRI machine is narrower with an opening on both and is lees harmful to the body by not using any ionizing radiation. The machine also contains an adjustable bed that is used to raise, lower, and insert the patient properly. Once the MRI films have been obtained and read by the radiologist, the will doctor determine if the patient has suffered from multiple sclerosis. If Multiple sclerosis has been seen and diagnosed, physicians will then begin to treat the patient with various medicines to stabilize the disease. According to the National Multiple Sclerosis society, Medicines such as Aubagio, Avonex, Betaseron, Copaxone, Extavia, Gilenya, Lemtrada, Novantrone, Plegridy, Rebif, Tecfidera, and Tysabri are all are used to treat M.S. and are FDA approve. (N.M.S.S pg. 1) Depending on the symptoms, other medications are provided that do not counteract with the other medications already given. If symptoms persist medications like steroids will help the body’s immune system to fight the affected areas According to web MD “Multiple sclerosis Health Center” MRI is not the only test used to diagnose MS, but MRI is a giant step in confirming a diagnosis. The Spinal Tap is also used due to the fluid in the spine holds important clues in diagnosis.” A Spinal Tap is a procedure that is done by inserting a needle to the space between the vertebral column and retracting fluid. Neurologist Dimitri P. Agamanolis stated “The cerebrospinal fluid (CSF) is produced from arterial blood by the choroid plexuses of the lateral and fourth ventricles by a combined process of diffusion, pinocytosis and active transfer.” Cerebral spinal fluid is located in the spaces of the spine providing mechanical lubricant for the spine to move without friction. Also the CSF is a shock absorber for the spine to minimize the impact from trauma and strain. By removing some fluid through the spinal tap, the fluid taken will give evidence of MS. Spinal fluid not is not only present in the back, it is also present in the brain for the same protection. But when removing the CSF it also comes with its side effects, like severe headaches and vertebral pain. If severe headaches are obtained the physician must put back the fluid for immediate relief. Another common test is the Evoked Potential Tests, a painless test used to measure electrical activity in the brain. By using electrodes with a conducting gel and taped to the scalp around the brain. The machine is programed to measure a wave form of signals from the brain and is copies to paper like an EKG. Physicians are able to read the brains response from the stimuli applied to the body and amount of time it responded. For instance, how long does it take the brain to respond to the eye when looking at a pattern? The time measured will determine how much of the disease has slowed the brain down from the stimulus, also known as latency. Other performance tests are studied as well to see more or less where the MS has taken over to diagnosed properly. The test results will determine the proper route to take when trying to stabilize the disease for the patient to have some relief.
