Clinical Information

  • MULTIPLE SCLEROSIS-. an autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. clinical manifestations include visual loss extra ocular movement disorders paresthesias loss of sensation weakness dysarthria spasticity ataxia and bladder dysfunction. the usual pattern is one of recurrent attacks followed by partial recovery see multiple sclerosis relapsing remitting but acute fulminating and chronic progressive forms see multiple sclerosis chronic progressive also occur. adams et al. principles of neurology 6th ed p903
  • MULTIPLE SCLEROSIS CHRONIC PROGRESSIVE-. a form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. if the clinical course is free of distinct remissions it is referred to as primary progressive multiple sclerosis. when the progressive decline is punctuated by acute exacerbations it is referred to as progressive relapsing multiple sclerosis. the term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form. from ann neurol 1994;36 suppl:s73 s79; adams et al. principles of neurology 6th ed pp903 914
  • MULTIPLE SCLEROSIS RELAPSING REMITTING-. the most common clinical variant of multiple sclerosis characterized by recurrent acute exacerbations of neurologic dysfunction followed by partial or complete recovery. common clinical manifestations include loss of visual see optic neuritis motor sensory or bladder function. acute episodes of demyelination may occur at any site in the central nervous system and commonly involve the optic nerves spinal cord brain stem and cerebellum. adams et al. principles of neurology 6th ed pp903 914

Information for Patients


Multiple Sclerosis

Multiple sclerosis (MS) is a nervous system disease that affects your brain and spinal cord. It damages the myelin sheath, the material that surrounds and protects your nerve cells. This damage slows down or blocks messages between your brain and your body, leading to the symptoms of MS. They can include

  • Visual disturbances
  • Muscle weakness
  • Trouble with coordination and balance
  • Sensations such as numbness, prickling, or "pins and needles"
  • Thinking and memory problems

No one knows what causes MS. It may be an autoimmune disease, which happens when your immune system attacks healthy cells in your body by mistake. Multiple sclerosis affects women more than men. It often begins between the ages of 20 and 40. Usually, the disease is mild, but some people lose the ability to write, speak, or walk.

There is no single test for MS. Doctors use a medical history, physical exam, neurological exam, MRI, and other tests to diagnose it. There is no cure for MS, but medicines may slow it down and help control symptoms. Physical and occupational therapy may also help.

Multiple sclerosis Multiple sclerosis is a condition characterized by areas of damage (lesions) on the brain and spinal cord. These lesions are associated with destruction of the covering that protects nerves and promotes the efficient transmission of nerve impulses (the myelin sheath) and damage to nerve cells. Multiple sclerosis is considered an autoimmune disorder; autoimmune disorders occur when the immune system malfunctions and attacks the body's own tissues and organs, in this case tissues of the nervous system.Multiple sclerosis usually begins in early adulthood, between ages 20 and 40. The symptoms vary widely, and affected individuals can experience one or more effects of nervous system damage. Multiple sclerosis often causes sensory disturbances in the limbs, including a prickling or tingling sensation (paresthesia), numbness, pain, and itching. Some people experience Lhermitte sign, which is an electrical shock-like sensation that runs down the back and into the limbs. This sensation usually occurs when the head is bent forward. Problems with muscle control are common in people with multiple sclerosis. Affected individuals may have tremors, muscle stiffness (spasticity), exaggerated reflexes (hyperreflexia), weakness or partial paralysis of the muscles of the limbs, difficulty walking, or poor bladder control. Multiple sclerosis is also associated with vision problems, such as blurred or double vision or partial or complete vision loss. Infections that cause fever can make the symptoms worse.There are several forms of multiple sclerosis: relapsing-remitting MS, secondary progressive MS, primary progressive MS, and progressive relapsing MS. The most common is the relapsing-remitting form, which affects approximately 80 percent of people with multiple sclerosis. Individuals with this form of the condition have periods during which they experience symptoms, called clinical attacks, followed by periods without any symptoms (remission). The triggers of clinical attacks and remissions are unknown. After about 10 years, relapsing-remitting MS usually develops into another form of the disorder called secondary progressive MS. In this form, there are no remissions, and symptoms of the condition continually worsen.Primary progressive MS is the next most common form, affecting approximately 10 to 20 percent of people with multiple sclerosis. This form is characterized by constant symptoms that worsen over time, with no clinical attacks or remissions. Primary progressive MS typically begins later than the other forms, around age 40.Progressive relapsing MS is a rare form of multiple sclerosis that initially appears like primary progressive MS, with constant symptoms. However, people with progressive relapsing MS also experience clinical attacks of more severe symptoms.
