What is nerve damage?

There are three main types of nerves in the body. Motor nerves send information to the muscles that control our voluntary movements. Our autonomous nerves check the involuntary body functions such as our heart rhythm. Nerve damage is any injury, whether less or severe, with nerve fibers in any area of ​​the body. Different causes may be responsible for nerve damage, which generally occur in one of three forms: neurotmes, neuapraxia and axonotmes.

There are dozens of different types of nerve damage, but almost all can be described by one of the three categories above. neurotmesis is the most serious form of nerve damage, resulting in a complete loss of function and continuity of the nerve. This may be due to heavy bruises, tearing or stretching nerve or surrounding tissue.

axonotmesis is a less serious form of nerve damage, mainly perceived as a result of injury, where the nerve is crushed or under too much pressure. Axon nerve is nAir, but the structural integrity of the nerve remains intact. This type of injury allows regeneration that can be completed for months or years.

Neurabraxia is the smallest type of damage and usually allows complete recovery within a few days or months. This is usually the result of pressure on the nerve that prevents its operation and blocks signals. Loss of blood supply can also cause neurabraxia.

Specific situation causes of nerve damage are as diverse as the disorders that people suffer. However, some conditions are known for their ability to cause nerve damage. Among them is mainly diabetes, often causing the type of nerve Damage called diabetic neuropathy . This term is non -specific and refers to many types of nerve damage caused by diabetes. About two -thirds of people with diabetes suffer from some form of neuropathy.

symptoms of diabetic neuropathy mohOU to intervene any part of the nervous system, but there are several common symptoms to be careful. Pain, feelings of armor and numbness on the limbs, as well as muscle atrophy in the legs and hands are some of the classic symptoms of this form of nerve damage. The digestive symptoms and sexual dysfunction, as well as the overall weakness, are also somewhat common for neuropathy of this type, although many people suffering do not experience any noticeable symptoms at all.
