Neurapraxia is best described as which of the following?

Neurapraxia is best described as which of the following?

• A. A stretch injury to a nerve resulting in transient paresthesia and weakness.
• B. A complete rupture of a nerve with permanent deficits.
• C. Chronic inflammatory nerve disease with continuous pain.
• D. A degenerative nerve condition with progressive loss.

Answer: (A)

The key idea here is that neurapraxia is the mildest form of nerve injury, involving a temporary block of nerve conduction without axon disruption. This usually results from compression or a mild stretch, causing transient sensory symptoms (like paresthesias) and weakness, but the nerve remains intact and there is no lasting damage to the axon. Recovery happens as myelin is restored, typically within days to weeks. So describing it as a stretch injury to a nerve resulting in transient paresthesia and weakness best fits neurapraxia because it captures the temporary nature, the preservation of the nerve’s structure, and the absence of axonal injury. The other descriptions imply more severe or different processes—nerve rupture with permanent deficits, chronic inflammatory disease with ongoing pain, or a degenerative progressive condition—in which neurapraxia would not be the correct framing.
