It is because Cold water in the caloric test will cause (fast phase) nystagmus in the opposite side. So if you put cold water in the LEFT ear it will cause fast phase nystagmus to the RIGHT and slow phase to the left. If you were to use warm water then the fast phase would be to the same ear you induced the warm water. Resting nystagmus: More common in acute peripheral vestibular disease. The rate of resting and positional nystagmus tends to be more rapid than central disease.

Typically, peripheral vertigo is more severe than central forms and is more likely to be associated with auditory symptoms (e.g., tinnitus, hearing loss), as well as nausea and vomiting. Other neurologic symptoms are generally associated with vertigo of central origin. Such symptoms might include diplopia, weakness, numbness, or incoordination.

They can move: side to side (horizontal nystagmus) up and down (vertical nystagmus) in a circle (rotary nystagmus) The movement can vary between slow and fast and usually happens in both eyes. The eyes may shake more when looking in certain directions.
