neurapraxia [noor″ah-prak´se-ah] failure of nerve conduction in the absence of structural changes, due to blunt injury, compression, or ischemia.neur·a·prax·i·a (nūr'ă-prak'sē-ă), Avoid the misspelling/mispronunciation neuropraxia. Avoid the jargonistic use of this word in the general sense of 'nerve lesion'.The mildest type of focal nerve lesion that produces clinical deficits; localized loss of conduction along a nerve without axon degeneration; caused by a focal lesion, usually demyelinating, but occasionally ischemic (when of shorter than a few hours' duration), followed by a complete recovery.
