What is central vertigo and demyelination disease?
Central vertigo is vertigo due to a disease originating from the central nervous system (CNS). In clinical practice, it often includes lesions of cranial nerve VIII as well. Individuals with vertigo experience hallucinations of motion of their surroundings.
Central vertigo may be caused by hemorrhagic or ischemic insults to the cerebellum, the vestibular nuclei, and their connections within the brain stem. Other causes include CNS tumors, infection, trauma, and multiple sclerosis.
Vertigo due to acoustic neuroma is also included in the broader category of central vertigo. An acoustic neuroma develops within the eighth cranial nerve, usually within the course of the internal auditory canal, yet it often expands into the posterior fossa with secondary effects on other cranial nerves and the brain stem.
