Common symptoms most frequently reported include a persistent sensation of motion usually<unk> scribed as rocking, swaying, or bobbing, disequilibrium with difficulty maintaining balance; it is seldom accompanied by a true spinning vertigo. Chronically fatigued, sufferers can become fatigued quickly with minimal exertion and some might experience neck and back pain. Other symptoms include the feeling of pressure in the brain, mostly around the frontal lobe area, headaches and/or migraine headaches, ophthalmodynia periodica (ice pick stabbing headaches in the early stages of MdDs), ear pain, ear fullness and possibly tinnitus. Fluctuations in weather also affect sufferers, in particularly hot weather and barometric pressure changes. Many have photo-sensitivity and find it more difficult to walk in the dark as well as other sensitivities to strong smells including chemical smells. Cognitive impairment ("brain fog") includes an inability to recall words, short term memory loss, an inability to multi-task, misspelling and mispronunciation of words, difficulty in concentrating. Many MdDS sufferers report they are unable to use a computer for any length of time due to the visual over-stimulation, and some are even unable to watch television. Symptoms can be increased by stress, lack of sleep, crowds, flickering lights, loud sounds, fast or sudden movements, enclosed areas and visual intolerance of busy patterns and scrolling movement. MdDS sufferers may have hypersomnia and can sleep up to 12 or more hours a day,<unk> pending on their symptom levels. Research reveals MdDS is not migraine-related and many sufferers have never had migraine symptoms prior to the onset of the disorder. However, for some MdDS sufferers there maybe have been a correlation between migraine and some pathophysiological overlap or even some other precipitating illness. The condition may be masked by a return to motion such as in a car, train, plane, or boat; however, once the motion ceases, the symptoms rebound or return, often at much higher levels than when the journey first commenced. The symptoms of MdDS may be extremely<unk> bilitating and fluctuate high and low on a daily basis; it greatly affects the daily life and working capacity of sufferers with many having to relinquish work; it also limits most other daily and social activities. Sufferers can have low quality of life in both the physical and emotional realms, comparable to people who have multiple sclerosis with many symptoms being of a similar nature. High levels of disequilibrium can contribute to suffers not being able to drive a car or walk far and this can create varying levels of anxiety in some or possibly<unk> pression due to the significant level of disability.
