What's causing your vertigo? Goggles may help with diagnosis

Vertigo is a form of severe dizziness that can result in a loss of balance, a feeling of falling, trouble walking or standing, or nausea. There is more than one type of vertigo, each with a different cause, and sometimes requiring different treatment. Now a proof-of-concept study has found that special goggles that measure eye movements during an episode of vertigo may help more accurately diagnose which type of vertigo a person has.
