The association of peripheral neuropathy (PN) and monoclonal dysglobulinemia has often been reported, although a direct link between the two is not readily established. Linkage is generally based on consideration of the clinical, electrophysiological and immunological findings along with details of the course. We report here a study of 66 ...
Rubin M - - 1996
A 35-year-old woman presented with a 4 year history of stepwise sensory loss which progressed in an asymmetrical fashion (mononeuropathy multiplex) and developed into a relatively symmetric polyneuropathy which was purely sensory by clinical and electrodiagnostic criteria. Sural nerve biopsy revealed demyelination with axonal sparing. Extensive laboratory evaluation failed to ...
Roh J K - - 1996
Medial medullary infarction is usually manifested as hypoglossal palsy, limb weakness, impairment of proprioception, and oculomotor disturbance. We report a case with the unusual presentation of sensory ataxia. A 71 year-old male presented with ataxia and disequilibrium. Bilateral dysmetria, truncal ataxia, Upbeat nystagmus, and impaired vibration and position sense were ...
Buchholz D W - - 1996
Migraine is conventionally regarded as a specific type of headache with a small set of associated neurologic symptoms. Yet, the true scope and frequency of migrainous phenomena are much greater than is generally acknowledged. Six cases are presented to illustrate some of the diverse manifestations of migraine: (1) transient global ...
