✦ Synopsis

We postulate that palatal myoclonus after infarction of the brainstem or cerebellum, o r both, is the manifestation of denervation supersensitivity secondary to lesions involving the dentatorubroolivary system. Two cases of our o w n and 31 from t h e English a n d French literature were analyzed i n order to determine t h e delay between t h e occurrence of presumed anatomical lesions and the recognition of palatal myoclonus. The intervals varied from 2 to 40 months with t h e median between 10 and 11 months. T h e natural history of palatal myoclonus following brainstern infarction seemed consistent w i t h the hypothesis.
