Ever experience episodes of dizziness, being off balance, or the room is spinning? You may have a form of vertigo. There are two categories for vertigo: peripheral and central. Peripheral vertigo occurs as a result of an inner ear problem or the vestibular nerve. Central vertigo occurs as a result of a problem in the brain, usually the cerebellum or vestibular nuclei. This can include strokes, tumors, infection, and multiple sclerosis. Most cases involve peripheral vertigo.
