neurapraxia

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, and followed by a complete recovery. Term is often misspelled (neuropraxia), and often used, incorrectly, as a synonym for nerve lesion. SEE ALSO: axonotmesis. [neur- + G. a- priv. + praxis, action]

neur·aprax·ia .n(y)u̇r-ə-'prak-sē-ə, .n(y)u̇r-(.)ā- n an injury to a nerve that interrupts conduction causing temporary paralysis but not degeneration and that is followed by a complete and rapid recovery

n.

temporary loss of nerve function resulting in tingling, numbness, and weakness. It is usually caused by compression of the nerve and there is no structural damage involved. Complete recovery occurs. Compare axonotmesis, neurotmesis.

neu·ra·prax·ia (noor″ə-prakґse-ə) [neur- + apraxia] failure of conduction in a nerve in the absence of structural changes, due to blunt injury, compression, or ischemia; return of function normally ensues. Called also axonapraxia. Cf. axonotmesis and neurotmesis.
