Multiple Sclerosis of Lumbar Spine
Multiple sclerosis (MS) is a recurring, potentially incapacitating disease that influences the central nervous system, which compose the brain and spinal cord. Multiple sclerosis is commonly thought to be an autoimmune disease, a condition in which the immune system attacks components of the body as if they're foreign.
In multiple sclerosis, the body incorrectly directs antibodies and white blood cells against proteins in the myelin sheath, a fatty substance that protects nerve fibers in the brain and spinal cord. This results in inflammation and harm to the sheath and eventually to the nerves that it surrounds. The result may be multiple areas of scarring (sclerosis). Ultimately, this injury can slow down or obstruct the nerve signals that control muscle coordination, strength, sensation and vision.
Multiple sclerosis influences approximately 300,000 people in the United States and possibly more than 1 million people around the world — including twice as many women as men. The majority of people experience their initial signs or symptoms between ages 20 and 40.
Multiple sclerosis is erratic and differs in severity. In a number of people, multiple sclerosis is a mild disease, but it can lead to permanent disability in others. Treatments can change the direction of the illness and ease symptoms.
Signs and symptoms
Signs and symptoms of multiple sclerosis differ extensively, depending on the site of affected nerve fibers. Multiple sclerosis symptoms may include:
Numbness or weakness in one or more extremity, which characteristically occurs on one side of the body at a time or the bottom half of the body Partial or total loss of vision, typically in one eye at a time, frequently with pain throughout eye movement

Signs and symptoms
Signs and symptoms of multiple sclerosis differ extensively, depending on the site of affected nerve fibers. Multiple sclerosis symptoms may include:
Numbness or weakness in one or more extremity, which characteristically occurs on one side of the body at a time or the bottom half of the body
Partial or total loss of vision, typically in one eye at a time, frequently with pain throughout eye movement
Double vision or blurring of vision
Tingling or pain in parts of the body
Electric-shock sensations that occur with particular head movements
Tremor, lack of coordination or unsteady gait
Fatigue
Dizziness
In certain cases, people with multiple sclerosis may also develop muscle stiffness or spasticity, slurred speech, paralysis, or problems with bladder, bowel or sexual function. Mental alterations, such as forgetfulness or difficulties with concentration, also may occur.
Causes
The central nervous system includes millions of nerve cells that send their electrical signals to and from the brain along wire-like extensions of the cells called axons, or nerve fibers. Myelin is the fatty substance that coats and protects these fibers, comparable to the way insulation protects electrical wires.
In people with multiple sclerosis, the immune system incorrectly damages the cells that manufacture the myelin sheath. As a result, myelin becomes inflamed and enlarged and separates from the nerve fibers. The removed myelin may ultimately be damaged. Rigid or hardened (sclerosed) patches of scar tissue develop over the fibers. After nerve impulses reach a injured region, some impulses are blocked or delayed from traveling to or from your brain. Eventually, this procedure leads to deterioration of the nerves themselves, which probably accounts for the permanent disabilities that may arise in MS.
Doctors and researchers don't recognize what causes this autoimmune response. Something appears to activate the condition in vulnerable people.
Hereditary factors may make some people more vulnerable to multiple sclerosis. But genetic inclination is only a fraction of the explanation. An amount of researchers consider the disorder is associated to a protein that imitates the myelin protein, which may be introduced into the body by a virus. Other researchers think that the immune system overreacts toward myelin proteins in people with MS, which leads to an abnormal predisposition to acquire autoimmune disease.
A period of disease activity (exacerbation) may be activated by a viral infection, such as a cold or flu, or by modifcations in the immune system throughout the initial six months following a pregnancy.

Patterns of MSWhatever the multiple sclerosis cause or trigger, the illness occurs in four main prototypes:
Relapsing remitting. This category of multiple sclerosis is distinguished by noticeably distinct outbreaks, followed by periods of remission. The flare-ups normally develop abruptly, last a few weeks or months, and then progressively vanish. The majority of people with MS have this type at the time of diagnosis.
Primary progressive. People with this less common type of multiple sclerosis experience a gradual weakening, lacking periods of remission. People with this form of MS are typically older than 40 when signs or symptoms start.
Secondary progressive. More than half the people with relapsing remitting MS ultimately go through a phase of continuous worsening referred to as secondary progressive MS. Abrupt relapses may occur, superimposed upon the continuous weakening that distinguishes this kind of multiple sclerosis.
Progressive relapsing. This is primary progressive MS with the addition of sudden incidents of new symptoms or deteriorating existing ones. This type is comparatively unusual.
Risk factors
These factors may increase the risk of developing multiple sclerosis:
Heredity. Multiple sclerosis is more frequent in people of Northern European ancestry. There also seems to be a hereditary factor to the condition, even though the risk to children of people affected by MS is fewer than 5 percent over their life span. Researchers believe that the inclination to acquire multiple sclerosis is inherited, but the illness is noticeable only when environmental causes are present.
Environmental factors. Environmental factors have some affect on multiple sclerosis. Many viruses and bacteria have been suspected of causing MS, most recently the Epstein-Barr virus, known also for causing infectious mononucleosis. Some studies have recommended that developing infection at a critical period of exposure may lead to conditions favorable to the growth of MS a decade or more later.
Geographical factors. Multiple sclerosis is more frequent in countries with moderate climates, including Europe, southern Canada, northern United States, and southeastern Australia. The cause is unidentified.
Screening and diagnosis
Multiple sclerosis can be complicated to diagnose. Many other conditions may create symptoms comparable to multiple sclerosis, but with a dissimilar prognosis and treatment.
There are no definite tests for multiple sclerosis. Eventually, the diagnosis relies on a determination that the clinical symptoms, radiological studies and laboratory studies suggest MS, and that no additional condition offer a improved explanation for them. The physician may base a multiple sclerosis diagnosis on the following:

Eventually, the diagnosis relies on a determination that the clinical symptoms, radiological studies and laboratory studies suggest MS, and that no additional condition offer a improved explanation for them. The physician may base a multiple sclerosis diagnosis on the following:
Medical history. The physician evaluates the signs and symptoms and their pattern.
Neurological examination. This exam thoroughly checks numerous elements of the nervous system, including the reflexes, muscle strength, muscle tone, and sensations of pain, heat, touch and vibration. The doctor may also monitor the gait, posture, coordination and equilibrium, and ask questions to establish the clearness of thinking, decisions and memory.
Magnetic resonance imaging (MRI) scan. The cylinder-shaped MRI scanner produces tissue-slice images on a computer from data created by a strong magnetic field and radio waves. The doctor can observe these images from any direction or plane.
This imaging procedure may disclose MS lesions, which are caused by myelin loss. An intravenous dye, gadolinium, will highlight "active" lesions that have developed within the past two months and this may help physicians identify whether the MS is in an active period, even if no symptoms are present demonstrating an attack of MS. Newer MRI methods can offer yet greater detail concerning the amount of nerve fiber damage or permanent myelin loss and revitalization.
Spinal tap (lumbar puncture). In this process, a doctor removes a minute sample of cerebrospinal fluid from within the spinal canal for laboratory analysis. This sample can demonstrate abnormalities related with multiple sclerosis, such as atypical levels of white blood cells or proteins. This method can also help rule out viral infections and additional conditions that can cause neurological symptoms comparable to those of MS.
Evoked potential test. This examination measures the electrical signals sent by the brain in reaction to stimuli. An evoked potential test may use visual stimuli or electrical stimuli, in which short electrical impulses are applied to the legs or arms.
Treatment
If the attacks are mild or occasional, the physician may monitor the condition.
Medications for relapsing MSFor a relapse type of the illness, the doctor may suggest treatment with disease-modifying medications initially in the course of disease. These medications for multiple sclerosis treatment include:

Medications for relapsing MSFor a relapse type of the illness, the doctor may suggest treatment with disease-modifying medications initially in the course of disease. These medications for multiple sclerosis treatment include:
Beta interferons. Interferon beta-1b (Betaseron) and interferon beta-1a (Avonex, Rebif) are genetically engineered duplicate of proteins that arise naturally in the body. They help battle viral infection and control your immune system.
These medications decrease but don't eliminate flare-ups of multiple sclerosis. It's unsure which of their various events lead to a decrease in disease activity and what their lasting benefits are. Beta interferons aren't used in combination with one another; only one of these medications is used at a time.
The Food and Drug Administration (FDA) has approved beta interferons only for people with relapsing forms of MS who can still walk. Beta interferons don't reverse injury and haven't been established to considerably change lasting growth of permanent disability. Some people acquire antibodies to beta interferons, which may cause them to be less efficient. Other people can't bear the side effects, which may consist of symptoms comparable to those of the flu (influenza).
Doctors normally suggest beta interferons for people who have more than one attack of MS a year and for those who don't recuperate well from flare-ups. The treatment may also be used for people who have a substantial increase of new lesions as seen on an MRI scan, even when there may not be major new symptoms of disease activity.
The FDA has approved the use of numerous beta interferons for people who've experienced a single attack that suggests multiple sclerosis, and who may be at risk of future attacks and developing distinct MS. Risk of MS may also be recommended when an MRI scan of the brain demonstrate lesions that forecast a high risk of adaptation to specific MS. Debate exists as to whether these people should take these costly and frequently problematic drugs for unspecified times, especially because some people do well both in the short term and long term without treatment. Some doctors choose to monitor people at high risk with follow-up exams and MRI scans to record any continuing inflammatory disease activity before suggestting long-term treatments such as beta interferon.

Glatiramer (Copaxone). This medication is an option to beta interferons for relapsing remitting MS. Doctors think that glatiramer works by blocking the immune system's attack on myelin. Side effects may include flushing and shortness of breath after injection.
Natalizumab (Tysabri).. It works by blocking the addition of immune cells to brain blood vessels — a essential step for immune cells to cross into the brain — therefore decreasing the immune cells' inflammatory action on brain nerve cells.
This drug was revealed to considerably decrease the occurrence of attacks in people with relapsing MS.
Because of the drug's risks, of a an uncommon, frequently deadly, brain disorder called progressive multifocal leukoencephalopathy. It's usually suggested only for people whose condition hasn't reacted to other types of MS treatments. Also, there has been no report directly comparing natalizumab to existing treatments to confirm whether it's better than existing treatments.
Other medications. Mitoxantrone (Novantrone) is a chemotherapy drug used for many cancers. This drug is also FDA-approved for treatment of aggressive types of relapsing remitting MS, as well as particular types of progressive MS.
Mitoxantrone may cause severe side effects, such as heart damage, after long-term use, so it's normally not used for longer than two to three years. And it's normally used for people with severe attacks or quickly developing disease who don't react to other treatments. Careful observation is critical for anybody on this medication.
Medications for progressive MSSome medications may reduce symptoms of progressive MS. They include:
Corticosteroids. Doctors most frequently recommend short courses of oral or intravenous corticosteroids to decrease inflammation in nerve tissue and to shorten the extent of flare-ups. Extended use of these medications, nevertheless, may cause side effects, such as osteoporosis and high blood pressure (hypertension), and the advantage of long-term treatment in multiple sclerosis isn't recognized.
Muscle relaxants. Baclofen (Lioresal) and tizanidine (Zanaflex) are oral treatments for muscle spasticity . Baclofen may briefly intensify weakness in the legs. Tizanidine controls muscle spasms without causing the legs to feel weak, but can be related with drowsiness or a dry mouth.

Medications to reduce fatigue. To help resist exhaustion, the doctor may recommend an antidepressant medication, the antiviral drug amantadine (Symmetrel) or a medication for narcolepsy called modafinil (Provigil). All drugs prescribed for this reason appear to work because of their stimulant properties.
Other medications. Many medications are used for the muscle stiffness, depression, pain and bladder control problems related with multiple sclerosis. Drugs for arthritis and medications that repress the immune system may slow down MS in some cases.
