My 101
The focus of OMRF’s Multiple Sclerosis Center of Excellence is to provide optimal medical care while advancing the understanding of MS—a disease of the central nervous system. Multiple sclerosis is an autoimmune disease of the brain and spinal cord caused by inflammation and degeneration. Inflammation causes damage to myelin, the protective covering that surrounds nerve cells. When this covering is damaged, nerve impulses are slowed and sometimes totally blocked. Degeneration can cause nerve cells to die prematurely. This combination of effects causes a variety of symptoms, including problems with vision, tremors, paralysis, painful spasms, imbalance, and cognitive changes.
From an MS clinical research perspective, we are interested in the visual system, cognition, balance and ambulation in MS.
The effects of MS in the brain commonly involve information processing in the visual system. The field of neuro-ophthalmology deals with problems with vision such as information coming from the eyes to the brain (called the afferent system) and the brain control of eyes positioning and movement (called the efferent system). Damage to the nerve pathways in the afferent system causes decrease or loss of vision, or blind spots in the visual fields. Damage to the efferent system creates misalignment of the eyes causes double vision or tracking abnormalities. Through clinical trials, we hope to determine if evaluating certain measurements in the eye can give us insight into degenerative processes in the brain and use those measurements as markers of disease progression.
One area of research we are pioneering is the effect of MS on balance. The delay of messages from the brain to the body can cause overcorrection causing patients to fall. It can alter normal gait, making it impossible to walk independently. We want to design objective ways to monitor changes and how the disease progression can impact patients’ function and safety. This will help identify the problems in a timely manner and assist us in intervening accordingly.
In addition to working with patients to address MS-related motor skills difficulties, sensory issues, cognition, and coordination, the Center participates in clinical trials to evaluate new medications directed at treating the disease.
We also work with scientists in the lab exploring basic science aspects of MS such as genetics and immunology. By learning more about the origins and behaviors of the disease, we hope to be able to slow or stop progression in current patients and prevent MS in others.
Research
Multiple sclerosis poses many scientific challenges that cover the spectrum from molecular research to clinical outcomes. A hindrance to all type of research and clinical interventions is the relative lack of objective quantifiable measures of disease progression. These “disease markers” are yet to be identified and validated and may include autoantibodies, cytokines, MRI parameters, anatomical neuronal evaluation, and disability measures.
A clinical research interest of our center is the use of computerized systems to evaluate gait and balance. This approach identifies changes before they are apparent on regular physical examinations and can be used to accurately monitor progression. Another is the use of optical coherence tomography to measure potential neuronal loss in the retina as an indicator of a corresponding process in the brain that is secondary to MS-induced inflammation and/or neurodegeneration.
