The best test to trigger a vertigo attack, creating nystagmus or eye movement, is the Dix-Hallpike Test. When you lie back quickly with your head turned to either direction, extending your neck, this challenges your inner ear or balance system. The eye movements and the direction of the nystagmus tell us which canal is involved.
We all have 'rocks' in our heads. These otolith crystals are attached in a gel with nerve sensors in them to tell our brain the direction of gravity, or where ''down' is. With a whiplash or head impact these crystals can get knocked around and they can crack. If they break loose they can end up in the semicircular canals and causing the 'room to spin'.
