Mononeuropathy

Mononeuropathy, as the name suggests, refers to pathology affecting a single nerve, resulting in the loss or decline of function of that nerve. It most often results from injury, but systemic disorders, such as eosinophilic granulomatosis with polyangiitis, can also cause it. The damage to the nerve may be localized to the myelin nerve sheath (which covers the nerve) or the nerve axon (which relays its signaling). Regardless, the damaged nerve cannot relay information effectively, thus producing clinical deficits.

Mononeuropathy can affect any part of the body, and presentation will depend on the nerve affected. The goal of treatment is to allow the patient to use the affected body part as much as possible and should thus be focused on maximizing function.
