WHAT IS MS? Multiple Sclerosis (MS) is a disease of people. It affects their entire lives, both physically and psychologically. Physically, the brain and the spinal cord (the central nervous system) are involved. Specifically, degeneration of myelin, a material which is composed mainly of fats and serves as an insulation for the nerves, much like the covering of an electric wire, degenerates. This fatty insulation allows a nerve to transmit its impulses with lightning-like speed, enabling people to move almost without thinking. The loss of this myelin insulation causes what is, in effect, a short-circuiting so that a person loses the ability to make smooth, rapid, and coordinated movements. Thus, MS is a demyelinating disease. With multiple sclerosis, the loss of myelin appears to the naked eye as a hardened sclerotic (scar) area. These areas are multiple within the central nervous system, thus the term multiple sclerosis. Different areas of the brain and spinal cord are responsible for different kinds of movements. For example, the cerebellum, an out-pocketing of the brain, is responsible for making coordinated movements. When an area of demyelination occurs in the cerebellum, coordinated movements become difficult. The neurological deficit is quite dependent on the region of the brain or spinal cord that has been affected. CHARACTERISTICS Characteristics of multiple sclerosis are: MS commonly begins between the ages of 15 and 50 Remissions and exacerbations (improvement and flareups) occur Scattered areas in the nervous system are diseased MS symptoms vary considerably from one individual to another and range from mild disturbances of gait and vision to severe weakness and loss of control. No two cases of multiple sclerosis are alike. While a number of patients with the disease are severely affected and progress to wheelchairs, this is by no means the rule. In fact, studies have shown that a majority of patients live fairly normal lives. Some patients may have only one or two attacks of neurological deficit in their entire life. A specific characteristic of MS is the presence of clinical symptoms affecting several different functions within the central nervous system (CNS), indicating the existence of multiple sites of damage. MS symptoms may fluctuate, or they may progress in severity. However, many patients have periods of stability that last many years. Even patients who ultimately progress to severe disability may have had long periods of less difficulty. Periods during which new symptoms appear or existing symptoms increase in severity, or leveling off of symptoms are termed remissions. Because of the large amount of variability in the presentation of the disease, no predictions as to the final outcome can be made. Statistically, however, the MS patient has every reason for optimism. CAUSE While the cause of multiple sclerosis has not been determined, several theories have been offered. Over the years these theories have evolved and changed. It was believed that allergies played a role in MS, and for many years antihistamines and histamine desensitizations were used. It is now known that this type of allergic response is not involved in MS, but clearly the system in the body which is responsible for recognizing foreign substances (the immune system) does not operate as it should. It appears to react strongly to some stimuli (antigens) and produces large amounts of antibodies to protect itself. This may result in a turning against itself and the development of what is called an "autoimmune reaction." Certain immune cells named T cells and others named B cells appear to behave differently in the person with MS. This behavior may well be determined by the genetic make-up of an individual. Thus, while MS is not a hereditary disease, there is a hereditary factor. While no virus has been consistently isolated in the MS patient, there are many who believe a virus is responsible for "turning on" the immune systm. Thus, the search for the virus "inducer" continues. The search is fueled by the fact that there appear to be environmental factors involved in the disease. The farther away from the equator, north and south, the more MS is seen. The l ocation of a person's first fifteen years of life seems to determine high risk versus low risk likelihood. DIAGNOSIS The diagnosis of multiple sclerosis is usually made as a result of clinical symptoms and a neurological examination. There is no one laboratory test which the clinician can use to make a firm diagnosis. However, in two-thirds of the cases of multiple sclerosis, an elevated gamma globulin is noted in the spinal fluid. Special proteins called oligoclonal bands are found in the spinal fluid of 80 percent of people with MS. Special studies looking at Igg production can be performed. Electrical tests may indicate short-circuiting in the central nervous system. These are called evoked response tests because a response from the nervous system is evoked with a specific stimulus. The stimulus may be visual, auditory, or through stimulation of an arm or leg. If it takes the stimulus an unusually long time to reach the brain, a short-circuiting may be the cause. Magnetic resonance imaging (MRI) allows the brain to be seen without surgery. MRI is particularly sensitive to MS, thus it has become an important aid to diagnosis. It is important to realize that other processes can make an MRI abnormal, and that it can miss MS every now and then. FREQUENT SIGNS AND SYMPTOMS SENSORY: Loss of vibratory sense; loss of temperature, pain and touch sensation; loss of position sense; dizziness; numbness; irritative sensations; electrical sensations; loss of joint sensibility. VISUAL: Jerky eyes, double vision, loss of color vision, blurred or dimmed vision, blindness. SPEECH: Scanning speech, slurred speech. MOTOR: Weakness, paralysis, c clumsiness, intention tremor, spasticity. BOWEL/BLADDER: Frequency, urgecy, incontinence, retention, constipation. FATIGUE MANAGEMENT GOOD HEALTH HABITS: Adequate rest, well balanced diet, prompt treatment of infections, capabilites conserved and develped to fullest extent. DRUGS: For relief of acute attacks, spasticity, bladder/bowel problems, fatigue and depression. PHYSICAL THERAPY: Maintenance of physical function, retraining. OCCUPATIONAL THERAPY THERAPEUTIC RECREATION COUNSELING: As indicated NURSING CARE: Observation, positioning, activities of daily living teaching, bowel and bladder training, etc. VOCATIONAL REHABILITATION
