Which of the following is NOT listed as a Vertebrobasilar insufficiency sign?

Vertebrobasilar insufficiency reflects reduced blood flow to the brainstem and cerebellum, so the signs come from posterior circulation dysfunction. Dizziness (vertigo) arises from vestibular pathway involvement, nystagmus appears due to brainstem involvement of eye movements, and diplopia results from impaired cranial nerve pathways controlling eye coordination. Fever, on the other hand, is not a feature of vascular insufficiency; it points toward infection or inflammation rather than ischemia. Hence fever is not listed as a vertebrobasilar insufficiency sign, while dizziness, nystagmus, and diplopia are.
