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.
Signs and Symptoms of Vertigo. Vertigo, or dizziness, refers to the sensation of spinning (subjective vertigo) or the perception that surrounding objects are moving or spinning (objective vertigo). Some patients describe a feeling of being pulled toward the floor or toward one side of the room. Moving the head, changing position, and turning while lying down often worsen vertigo. The sudden onset of vertigo usually indicates a peripheral vestibular disorder (inner ear disturbance; e.g., BPPV, MÃ©niÃ¨re disease, vestibular neuritis, labyrinthitis).
