What causes Vertigo?
Vertigo is the complaint of dizziness, often reported as the room spinning, caused by vestibular (inner ear) dysfunction or cranial nerve dysfunction. It affects 42% of adults over their lifetime. Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of vertigo. It is caused by calcium carbonate crystals (otoconia) that break free from the utricle and float freely in the semi-circular canals (in the inner ear). There are 2 types of BPPV - Canalithiasis where the crystals are freely floating in the canal and - Cupulolithiasis where the crystals are stuck to the cupula. Other causes of dizziness include vestibular migraines, cervicogenic vertigo (upper neck), vestibular neuritis, Meniere's disease, concussion, perilymphatic fistula, vestibular Schwannoma.
