During an attack of multiple sclerosis, the immune system triggers inflammation along nerves and in glial cells. Oligodendrocytes are damaged and myelin is damaged and detaches from the axon. Messages that pass along a demyelinated nerve are delayed or blocked. Currently, there is no single test to diagnose MS.
However, there are four key features that help ensure the diagnosis:. First of all, are there typical symptoms of multiple sclerosis? Again, this is loss of vision in one eye, loss of power in an arm or leg, or sensory alteration in an arm or leg that lasts longer than 24 hours. Second, do you have any physical exam results that are consistent with multiple sclerosis? Secondly, is MRI of the brain or spine compatible with multiple sclerosis? Now, it's important to note that 95 percent of people over 40 undergo an abnormal brain MRI, just like many of us have wrinkles on our skin. Finally, are the results of the cerebrospinal fluid analysis consistent with MS? Your doctor may recommend blood tests to detect other diseases that share the same symptoms.
They may also recommend an OCT test or an optical coherence tomography scan. This is a brief scan of the thickness of the layers at the back of the eye. In multiple sclerosis, the protective layer of nerve fibers (myelin) is damaged and, over time, can be destroyed. Depending on where the nerve damage occurs, multiple sclerosis can affect vision, sensitivity, coordination, movement, and bladder or bowel control.
Multiple sclerosis (MS) is a potentially disabling disease of the brain and spinal cord (central nervous system). There is no cure for multiple sclerosis. However, there are treatments to help speed recovery from attacks, modify the course of the disease, and control symptoms. In multiple sclerosis, the protective layer of nerve fibers (myelin) of the central nervous system is damaged.
This creates an injury that, depending on the location in the central nervous system, can cause symptoms such as numbness, pain, or tingling in some parts of the body. The signs and symptoms of multiple sclerosis can vary widely from person to person and throughout the disease, depending on the location of the affected nerve fibers. The cause of multiple sclerosis is unknown. It is considered an immune-mediated disease in which the body's immune system attacks its own tissues.
In the case of multiple sclerosis, this malfunction of the immune system destroys the fatty substance that covers and protects nerve fibers in the brain and spinal cord (myelin). Multiple sclerosis care at Mayo Clinic. Multiple sclerosis is caused by damage to the myelin sheath. This cover is the protective cover that surrounds nerve cells.
When this nerve covering is damaged, nerve signals slow down or stop. Nerve damage is caused by inflammation. Inflammation occurs when the body's own immune cells attack the nervous system. This can occur along any area of the brain, optic nerve, and spinal cord.
MS attacks axons in the central nervous system protected by myelin, which is commonly referred to as white matter. Multiple sclerosis also damages nerve cell bodies, which are found in the gray matter of the brain, as well as the brain's own axons, spinal cord and optic nerves that transmit visual information from the eye to the brain. As the disease progresses, the outermost layer of the brain, called the cerebral cortex, contracts in a process known as cortical atrophy. It's a neurological condition, meaning it affects the nerves.
Multiple sclerosis occurs when the immune system attacks nerves by mistake. It damages the nerves in the brain and spinal cord. Multiple sclerosis is a disorder of the central nervous system characterized by decreased nerve function, with initial inflammation of the protective layer of the myelin nerve and, eventually, scarring. Symptoms and the severity of symptoms vary widely and can develop into episodes of crisis that alternate with episodes of remission.
Multiple sclerosis (MS) damages nerve fibers in the central nervous system. Over time, it can cause vision problems, muscle weakness, loss of balance, or numbness. Several drug treatments can limit nerve damage and slow the progression of the disease. Multiple sclerosis (MS) is a long-term (chronic) central nervous system disease.
It's thought to be an autoimmune disorder, a condition in which the body attacks itself by mistake. Multiple sclerosis is an unpredictable disease that affects people differently. Some people with multiple sclerosis may have only mild symptoms. Others may lose the ability to see clearly, write, speak, or walk when communication between the brain and other parts of the body is interrupted.
Multiple sclerosis can be a particularly debilitating disorder because the body essentially attacks itself. The disease is confirmed when symptoms and signs appear and are related to different parts of the nervous system at more than one interval and after other alternative diagnoses have been ruled out. Multiple sclerosis (MS) is the most common disabling neurological disease among young adults, and symptoms usually appear between the ages of 20 and 40. Because the symptoms of multiple sclerosis may resemble other nervous system disorders, your doctor will want to rule it out.
To understand what happens in multiple sclerosis, it's helpful to understand how the central nervous system works. The symptoms of multiple sclerosis depend on the severity of the inflammatory reaction, as well as on the location and extent of the plaques, which appear mainly in the brain stem, the cerebellum (involved in balance and coordination of movement, among other functions), the spinal cord, the optic nerves and the white matter that surrounds the cerebral ventricles (cavities filled with fluid). Multiple sclerosis (MS) is an unpredictable disease of the central nervous system that interrupts the flow of information within the brain and between the brain and the body. A neurologist is a doctor who specializes in treating conditions that affect the nervous system, including the brain and spinal cord.
Because multiple sclerosis can damage nerves anywhere in the brain or spinal cord, you may have symptoms in many parts of your body. Inflammation of the optic nerve (optic neuritis) or damage to the myelin that covers the nerve fibers of the visual system can result in blurred or gray vision, temporary blindness in one eye, loss of normal color vision, depth perception, or loss of vision in parts of the visual field. Relapsing remitting multiple sclerosis is a type of multiple sclerosis in which there are relapses (symptoms worsen) followed by recovery (that is, when it comes to “remission”). In some cases, multiple sclerosis causes disability and loss of physical or mental function.
Myelin is a substance that forms the protective sheath (myelin sheath) that covers nerve fibers (axons). Multiple sclerosis is a disease that affects the central nervous system (brain, spinal cord, and optic nerves). The central nervous system connects everything the body does, so multiple sclerosis can cause many different types of symptoms. .
