1. Vertigo-associated disorders  (Trust Mark: Doctor-Reviewed)
Vertigo is a sensation of motion or spinning that is often described as dizziness. Vertigo is not the same as light-headedness. People with vertigo feel as though they are actually spinning or moving, or that the world is spinning around them.• Reviewer: David C.
