This type of nerve damage may cause paralysis of the motor, sensory, and autonomic functions, and is mainly seen in crush injury. [2] If the force creating the nerve damage is removed in a timely fashion, the axon may regenerate, leading to recovery. Electrically, the nerve shows rapid and complete degeneration, with loss of voluntary motor units.
Age: Recovery of a nerve after surgical repair depends mainly on the age of the patient. Young children can recover close-to-normal nerve function. In contrast, a patient over 60 years old with a cut nerve in the hand would expect to recover only protective sensation; that is, the ability to distinguish hot/cold or sharp/dull. [13]
The severe pain of HNA can be controlled with an anti-inflammatory drug such as prednisone, although it is unknown whether these anti-inflammatory drugs actually slow or stop the nerve degeneration process. Nerve regeneration after an episode is normal, and in less severe cases a full recovery of the nerves and muscles can be expected.
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
Existing treatments aim to suppress the immune system to prevent further damage to nerve cells. A new study has developed a treatment that can help regenerate myelin with the potential to stop and ...
The outcome of nerve repair is dependent on the degree of the nerve injury and the circumstances at the site of injury. [5] Since neurapraxia is the least serious form of peripheral nerve injury, recovery and treatment are not extensive. Once the cause of neurapraxia is eliminated, recovery of the lesions in the nerve occurs within a short time ...
Wallerian degeneration is an active process of degeneration that results when a nerve fiber is cut or crushed and the part of the axon distal to the injury (which in most cases is farther from the neuron's cell body) degenerates. [1]
This damage can cause neuronal apoptosis, programmed cell death, which leads to neuropathy. Additionally, functional neuronal deficits have been identified, independent of structural damage, e.g. ion channelopathy, impaired spike encoding in the central [5] and peripheral nervous system.
