Vertigo is the most common type of dizziness. The most common diseases that result in vertigo are benign paroxysmal positional vertigo (BPPV), MÃ©niÃ¨re's disease, and labyrinthitis. Less common causes include stroke, brain tumors, brain injury, multiple sclerosis, and migraines.
Vertigo and dizziness affect your perception of motion and balance. Objective vertigo affects the brain's perception of motion, causing you to feel that your surroundings are spinning. Dizziness affects your balance, causing you to feel lightheaded, woozy, or nauseous.
