neuropraxía

Neuropraxia is a mild form of peripheral nerve injury. It is the least severe type of nerve damage, characterized by a temporary disruption of nerve function without anatomical damage. In neuropraxia, the nerve fibers themselves remain intact, and there is no structural damage to the nerve sheath. The cause is typically compression, contusion, or stretch, which leads to a temporary block in the nerve's ability to conduct electrical signals.

Symptoms of neuropraxia usually manifest as a loss of motor and/or sensory function distal to the site of injury. This can include weakness, numbness, tingling, or a pins-and-needles sensation. The severity of symptoms depends on the nerve involved and the extent of the compression or insult. Importantly, there is no loss of nerve continuity, meaning the axon and its surrounding myelin sheath are not severed or significantly damaged.

Recovery from neuropraxia is typically rapid and complete. Without structural damage, the nerve's conductive capacity can be restored relatively quickly. The time course for recovery can vary, ranging from a few days to several weeks or months. In most cases, full function returns with no residual deficits. Treatment is usually supportive, focusing on rest, avoiding further trauma to the affected nerve, and sometimes physical therapy to maintain muscle strength and range of motion during the recovery period.
