Abstract

Only a few cases of primary position downbeat nystagmus (PPDN) during an acute vestibular migraine (VM) have been reported but without details of the nystagmus pattern. A 15-year old girl with a history of recurrent headache and oscillopsia presented with PPDN, which lasted about 12 hours and resolved spontaneously. VM should be considered in the differential diagnosis of PPDN which are presumed to be caused by the dysfunction of the vestibular cerebellum and its connection. KeyWords:Vertigo, Migraine, Cerebellum
