Vertigo

**Definition:** Central vertigo is usually a result of an abnormal processing of the vestibular sensory input by the central nervous system due to either a disruption of central integrators (i.e. brain stem, cerebellum) or a sensory information mismatch (i.e. from the cortex). Lesions that affect the vestibular nerve or root entry zone (i.e. cerebellopontine angle [CPA] lesions) result in imbalance by affecting primary vestibular sensory information

**Inclusions:** - Central positional nystagmus
