Definition of Mononeuropathy

Mononeuropathy is damage to a single nerve or nerve group, which results in , sensation, or other function of that nerve.

Causes, incidence, and risk factors

Mononeuropathy is a type of damage to nerves outside the brain and spinal cord ().


Symptoms depend on the specific nerve affected, and may include:

Signs and tests

A detailed medical history is needed to determine the possible cause of the disorder. An examination and nerve and muscle testing may show a loss of feeling, movement, or other problems with a specific nerve. Reflexes may be abnormal.


The goal of treatment is to allow you to use the affected body part as much as possible.

Expectations (prognosis)

Mononeuropathy may be disabling and painful. If the cause of the nerve dysfunction can be found and successfully treated, a full recovery is possible and even likely in some cases.
