The causes of nerve damage are grouped into categories including those due to paraneoplastic causes (neuropathy secondary to cancer), immune mediated, infectious, inherited or degenerative causes and those due to toxin exposure. In idiopathic sensory neuronopathy no cause is identified. Idiopathic causes account for about 50% of cases. [2]
There are three types of nerve damage, including: "motor nerve damage, sensory nerve damage, and autonomic nerve damage". [2] These sensory, motor and autonomic fibres which make up peripheral nerves have specific functions, which means that their involvement in neuropathic disorders can lead to “diverse symptoms, signs and electrodiagnostic ...
Guillain–Barré syndrome – nerve damage. Neuroregeneration in the peripheral nervous system (PNS) occurs to a significant degree. [5] [6] After an injury to the axon, peripheral neurons activate a variety of signaling pathways which turn on pro-growth genes, leading to reformation of a functional growth cone and regeneration.
[23] [3] It is classified as a sensory ganglionopathy due to involvement of these ganglia. [ 61 ] [ b ] In electrodiagnostic testing , it has characteristic non-length-dependent abnormalities of sensory action potentials that occur globally, rather than distally decreasing sensory nerve action potential amplitudes.

Clark's rule is a medical term referring to a mathematical formula used to calculate the proper dosage of medicine for children aged 2–17 based on the weight of the patient and the appropriate adult dose. [1] The formula was named after Cecil Belfield Clarke (1894–1970), a Barbadian physician who practiced throughout the UK, the West Indies ...
It was noted that after 3 weeks, a mixed nerve defect had undergone substantial regeneration when paired with a motor nerve graft or a mixed nerve graft. In comparison, a sensory nerve graft was statistically less affective in regeneration, looking specifically at nerve fiber count, percent nerve, and nerve densities as the main three ...
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
Denervation can occur as a consequence of nerve injury. The three primary categories of nerve injury are neurapraxia, axonotmesis, and neurotmesis, each corresponding to varying degrees of damage and potential for recovery. In cases of nerve injury, the brain demonstrates an impressive ability to rewire or reorganize its neuronal circuitry ...
