Causes
Peripheral vestibular: ear infections, idiopathic vestibular syndrome of the older dog (cause unknown, good prognosis). Central vestibular: problems in the brain (more serious). In cats, it is sometimes linked to infections.
Diagnosis
A neurological examination to determine whether it is peripheral or central. Depending on the case, otoscopy, blood tests or an MRI scan.
Treatment
Treating the underlying cause (e.g. the ear infection) plus supportive care (controlling nausea, help with eating/drinking). Idiopathic vestibular syndrome in the older dog usually improves greatly within days to weeks.
Prevention
Treat ear infections promptly.
