Multiple mononeuropathy

[Dorothey Allen]

Multiple mononeuropathy is the simultaneous malfunction of two or more peripheral nerves in separate areas of the body. It causes abnormal sensations and weakness.
(See also Overview of the Peripheral Nervous System.)
Multiple mononeuropathy typically affects only a few nerves, often in different areas of the body. In contrast, polyneuropathy affects many nerves, usually in about the same areas on both sides of the body. However, if multiple mononeuropathy involves many nerves, it may be difficult to distinguish from polyneuropathy.
Several disorders can cause multiple mononeuropathy, and each disorder produces characteristic symptoms.
The most common cause is probably

Diabetes, although diabetes more commonly causes polyneuropathy

Other common causes of multiple mononeuropathy include

Vasculitis (inflammation of blood vessels, as occurs in polyarteritis nodosa)
Systemic lupus erythematosus (lupus)
Sj
