What is peripheral neuropathy caused by?

summary

Peripheral nerve refers to the brain nerve, spinal nerve, autonomic nerve and ganglion besides olfactory nerve and optic nerve. Peripheral nerve disease refers to the primary damage to the structure or function of the peripheral nervous system. Peripheral nerves are divided into sensory afferent and motor efferent. The former consists of posterior root of spinal nerve, posterior root ganglion and sensory nerve. So, what is peripheral neuropathy caused by? Let's find out.

What is peripheral neuropathy caused by?

The first reason is infection; Often associated with or secondary to a variety of acute and chronic infections, such as pharyngitis, tracheobronchitis, pneumonia, dysentery, tuberculosis, infectious hepatitis, typhoid, mumps, etc., a small number of pathogens can be caused by direct invasion of peripheral nerves, such as leprosy neuritis. Syphilis and AIDS can lead to both central nervous system damage and peripheral neuropathy. When the patient may not have obvious infection symptoms after catching cold, he may also have simple peripheral neuritis symptoms, and serious symptoms may cause nerve trunk and nerve root.

The second reason is the disorder of nutrition and metabolism; Such as vitamin B or folic acid deficiency, hypothyroidism, diabetes, uremia, chronic gastrointestinal diseases, liver disease and pregnancy. Long term drinking can easily lead to peripheral neuropathy. In addition to cancer and cardiovascular disease, people who smoke a lot for a long time are also prone to peripheral neuropathy.

The third reason is poisoning or drug-induced; Heavy metals (such as lead, arsenic, mercury, phosphorus, thallium, etc.), furans (such as furazolidone), berberine, isoniazid, streptomycin, phenytoin sodium, carbamazepine, chemotherapy drugs, hair dyes, organophosphorus pesticides and a variety of chemical agents and other organic compounds.

matters needing attention

The general drug treatment of peripheral nerve lesions is mainly used in the early stage of the lesion, and the surgical treatment is used for the conservative treatment of invalid and suitable or need surgical treatment. The rehabilitation treatment should be carried out in the early and recovery stage of peripheral nerve lesions, or before and after the surgical treatment. The purpose of rehabilitation treatment of peripheral nerve lesions is to eliminate or reduce pain, prevent and relieve muscle and tendon contracture, joint stiffness, prevent muscle atrophy, enhance muscle strength, restore motor and sensory function, and finally restore the life and work ability of patients. The affected limb function can not be completely recovered or completely recovered. It should be designed according to the specific situation. Prepare the auxiliary equipment. The compensatory function training was carried out.
