10 Most Rare Diseases

Jakarta, severe diseases such as diabetes, cancer, stroke or heart already widely known. But actually there is another fee that is a rare disease. Any disease that?

As quoted from DiscoveryHealth, following 10 in the world's rarest diseases are most associated with the nerve:

1. Progressive multifocal leukoencephalopathy (PML)

PML is a neurological disorder characterized by destruction of myelin, the protective sheath surrounding nerve fibers in the central nervous system and spinal cord.

The disease is caused by JC virus. This virus was found in 85 percent of the adult population in general, but the virus remains dormant for people to remain healthy and strong immune system. PML occurs in 1 in 200,000 people.

2. Neurologic Paraneoplastic Syndromes (PNS)

PNS are conditions that affect the nervous system, ie brain, spinal cord, nerves are also muscle. The term 'paraneoplastic' means nerve syndrome is not caused by the tumor itself, but by an autoimmune reaction that produces the tumor. In many patients, the immune response can cause damage to the nervous system that far exceeds the damage done to the tumor.

3. Dercum Disease

Dercum disease is a rare disorder, characterized by a growth of fat tissue (lipoma) is painful. This growth usually occurs on the hands, upper arms, legs above, also under the skin (subcutaneous).

Dercum disease often causes great pain. In some cases, affected individuals may also experience weight gain, depression, lethargy, and confusion. The exact cause of Dercum disease is not known.

4. Fahr disease

Fahr disease is a degenerative neurological disorder that rarely occurs. It is characterized by abnormal calcium deposits (calcification) and the related loss of cells in certain regions of the brain, such as the basal ganglia.

Fahr disease can cause damage to cognitive abilities (dementia), loss of motor skills, muscle stiffness, paralysis and even blindness.

5. Devic disease

Neuromyelitis Optica or Devic disease is a chronic disorder characterized by inflammation of nerve tissue in the optic nerve (optic neuritis) and inflammation of the spinal cord (myelitis). In the early stages, symptoms may be similar to Devic disease multiple sclerosis.

6. Tardive dyskinesia (TD)

TD is a neurological movement disorder caused by the spontaneous use of dopamine receptor drugs to treat mental conditions or specific digestion. Long-term use of these drugs may produce biochemical abnormalities in brain regions known as the striatum.

Dyskinesia dystonia is a more severe form of TD, which swirling motion over the neck and trunk muscles which stand out more slowly.
