Clinical InformationClinical

  • Diabetic Neuropathies

    peripheral, autonomic, and cranial nerve disorders that are associated with diabetes mellitus. these conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (vasa nervorum). relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see oculomotor nerve diseases); mononeuropathy; mononeuropathy multiplex; diabetic amyotrophy; a painful polyneuropathy; autonomic neuropathy; and thoracoabdominal neuropathy. (from adams et al., principles of neurology, 6th ed, p1325)

  • Mononeuropathies

    disease or trauma involving a single peripheral nerve in isolation, or out of proportion to evidence of diffuse peripheral nerve dysfunction. mononeuropathy multiplex refers to a condition characterized by multiple isolated nerve injuries. mononeuropathies may result from a wide variety of causes, including ischemia; traumatic injury; compression; connective tissue diseases; cumulative trauma disorders; and other conditions.
