Danette C. Taylor, DO, MS, FACN
Dr. Taylor has a passion for treating patients as individuals. In practice since 1994, she has a wide range of experience in treating patients with many types of movement disorders and dementias. In addition to patient care, she is actively involved in the training of residents and medical students, and has been both primary and secondary investigator in numerous research studies through the years. She is a Clinical Assistant Professor at Michigan State University's College of Osteopathic Medicine (Department of Neurology and Ophthalmology). She graduated with a BS degree from Alma College, and an MS (biomechanics) from Michigan State University. She received her medical degree from Michigan State University College of Osteopathic Medicine. Her internship and residency were completed at Botsford General Hospital. Additionally, she completed a fellowship in movement disorders with Dr. Peter LeWitt. She has been named a fellow of the American College of Neuropsychiatrists. She is board-certified in neurology by the American Osteopathic Board of Neurology and Psychiatry. She has authored several articles and lectured extensively; she continues to write questions for two national medical boards. Dr. Taylor is a member of the Medical and Scientific Advisory Council (MSAC) of the Alzheimer's Association of Michigan, and is a reviewer for the journal Clinical Neuropharmacology.

How is multiple sclerosis diagnosed?
As in all conditions, the history of the patient is important. Many patients with multiple sclerosis have experienced various symptoms which were ignored or attributed to other events or illnesses. Even if no prior symptoms are recalled by a patient, the remaining medical history is needed to exclude other conditions which might mimic multiple sclerosis.
Once the history is obtained, a complete physical examination is required. Physicians look for signs of injury to the central nervous system (either the brain or spinal cord); findings on the examination can help a doctor determine which area of the central nervous system (CNS) is involved.
Imaging studies help to confirm a diagnosis of multiple sclerosis. The most common test done is a magnetic resonance image, or MRI. CT scans, while helpful in finding some brain injuries, are unable to reveal the changes associated with multiple sclerosis with as much detail as an MRI. MRIs can be used to image the brain and the spinal cord.
A spinal tap, or lumbar puncture, is done to collect a small amount of cerebrospinal fluid. Testing can be done on this fluid to confirm the presence of protein, inflammatory markers, and other substances. With the routine use of MRI, performing a spinal tap is not considered mandatory, unless there are questionable findings on the MRI or other questions to answer.
Evoked potential testing (visual evoked potentials, brainstem auditory evoked potentials, and somatosensory evoked potentials) can show slowed response times in the optic nerve, the auditory nerve, the spinal cord, or the brainstem. While helpful, these tests are not specific for changes seen in multiple sclerosis.
When multiple sclerosis is suspected, blood work and testing to exclude other conditions, such as Lyme disease, vasculitis, lupus, human immunodeficiency virus (HIV), and processes which lead to multiple strokes, are often done as well.
