How can vertigo cause dizziness?

ANSWER

Does it feel like you're spinning or the room is moving around you? That's a classic sign of a particular type of dizziness called vertigo. It's more than feeling off-kilter and usually gets worse when you move your head. This is a symptom that there is an issue in the inner ear or part of the brainstem governing balance. The most common kind is benign paroxysmal positional vertigo, or BPPV. Your inner ear is a complicated system of canals filled with fluid. These let your brain know how your head is moving. With BPPV, tiny bits of calcium in part of your inner ear get loose and move to places they don't belong. The system doesn't work the way it should and sends your brain the wrong signals. It's often caused by the natural breakdown of cells that happens with age. A head injury can cause it, too.
