Symptoms can vary in intensity from day to day and even throughout the day. Many times the reason for these changes cannot be clearly identified. Many report increased symptoms toward the end of the day.
This is most likely caused by an increase in stress and fatigue. Although common triggers have not been clinically identified, some report an increased rocking sensation with stress, fatigue, illness, dark rooms, bright lights, busy patterns, shopping in supermarkets and grocery stores, household chores like ironing, hovering, working with computers and walking in crowds. For some the symptoms decrease over time, but not always.
It has also been reported that symptoms seem to go temporarily unnoticed or seem to “disappear” during car rides, short train travel or other steady motion experiences. Additionally, some sufferers have experienced re-occurrences triggered by events such as subsequent cruises, air travel, upper respiratory infections and other motion experiences
Symptoms not typically associated with MdDS include:
- Rotational/spinning vertigo
- Double vision
- Nystagmus
