ABSTRACT

Neuropathy is a nonspeci‚c term used to describe a lesion located somewhere in the PNS. A lesion a„ecting the nerve root itself results in a radiculopathy, whereas a lesion to the plexus results in a plexopathy. If the nerve itself is lesioned it is called a:

• Mononeuropathy if one individual nerve is lesioned. • Mononeuropathy multiplex if two or more unrelated nerves are lesioned, resulting

in multifocal disease (i.e., dysfunction of a nerve in an arm and nerve in a leg). • Polyneuropathy if the disease process is generalized, resulting in a symmetric

involvement of nerves on both sides of the body (i.e., the nerves involved in the right leg are the same as the nerves involved in the left leg).
