Symptoms
MdDS patients feel as if theyre rocking, bobbing and/or swaying even when they're not. This "non-spinning vertigo" is present continuously or for most part of the day.
Onset occurs within 48 hours after the end of exposure to passive motion.
Symptoms may temporarily reduce when in passive motion (e.g. when driving a car).
Symptoms continue for more than 48 hours, but this can happen in different ways:
In evolution: symptoms are ongoing but the observation period has been less than 1 month
Transient: symptoms resolve at or before 1 month and the observation period extends at least to the resolution point
Persistent: symptoms last for more than 1 month.
Sometimes symptoms are better accounted for by another disorder, which makes it crucial to get a diagnosis from an expert.
The diagnostic criteria for MdDS have been classified by the Bárány Society.
