Neuropraxia is a type of peripheral nerve injury, and is known as the mildest form of nerve injury. It is classified as a transient conduction block of motor or sensory function without nerve degeneration, although loss of motor function is the most common finding. In cases of neuropraxia, autonomic function is preserved. Patients are usually able to fully recover within a period of weeks to months.
Nerve damage is classically described in terms of anatomical injury. Nerves are comprised of the endoneurium that surrounds axons. These include both individual axons that are covered in myelin and groups of axons than are unmyelinated. These collections are surrounded by a layer called perineurieum, and the epineurium forms the outermost layer. Vascular networks are contained within the epineurium to supply the capillaries to the endoneurium. Neuropraxia by definition does not involve damage to the axon.
