How does one get vertigo?

False motion. Vertigo is a sense of false motion. It can be caused by a problem in your inner ear (peripheral vertigo) or by a problem in the brainstem (central vertigo). The inner ear has 3 separate balance canals that help keep your balance in space during movement. The brainstem is responsible for processing all the information from both inner ears, your eyes, and your muscles to help with balance.
