Sensory Polyneuropathy
Polyneuropathy (wikt:poly-, poly- + wikt:neuro-, neuro- + wikt:-pathy, -pathy) is damage or disease affecting peripheral nerves (peripheral neuropathy) in roughly the same areas on both sides of the body, featuring weakness, numbness, and burning pain. It usually begins in the hands and feet and may progress to the arms and legs and sometimes to other parts of the body where it may affect the autonomic nervous system. It may be acute (medicine), acute or chronic (medicine), chronic. A number of different disorders may cause polyneuropathy, including diabetes and some types of Guillain–Barré syndrome. Classification Polyneuropathies may be classified in different ways, such as by ''cause'', by ''presentation'', or by ''classes'' of polyneuropathy, in terms of which part of the nerve cell is affected mainly: the axon, the myelin sheath, or the cell body. * ''Distal axonopathy'', is the result of interrupted function of the peripheral nerves. It is the most common response of neur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charcot–Marie–Tooth Disease
Charcot–Marie–Tooth disease (CMT) is a hereditary motor and sensory neuropathy of the peripheral nervous system characterized by progressive loss of muscle tissue and touch sensation across various parts of the body. This disease is the most commonly inherited neurological disorder, affecting about one in 2,500 people. It is named after those who classically described it: the Frenchman Jean-Martin Charcot (1825–1893), his pupil Pierre Marie (1853–1940), and the Briton Howard Henry Tooth (1856–1925). There is no known cure. Care focuses on maintaining function. CMT was previously classified as a subtype of muscular dystrophy. Signs and symptoms Symptoms of CMT usually begin in early childhood or early adulthood but can begin later. Some people do not experience symptoms until their early 30s or 40s. Usually, the initial symptom is foot drop early in the course of the disease. This can also cause hammertoe, where the toes are always curled. Wasting of muscle tissue of ...
