OBJECTIVE: @entity392 ( @entity392 ) is a form of @entity1296 . Many @entity1 report fewer symptoms when they get up with an aggravation over of the day. Therefore, the change in the severity of the symptoms during daytime was evaluated and compared with other chronic @entity394 : bilateral vestibulopathy (BVP) and @entity346 ( @entity346 ). DESIGN/METHODS: In a prospective study 131 @entity1 with @entity392 , 108 @entity1 with BVP, and 38 @entity1 with @entity346 filled out a questionnaire asking about the symptom intensity (0 = no symptoms, 1 = light, 2 = moderate, 3 = strong) at 6 time-points. The influences of duration of the disease and physical activity on the change of symptoms were also investigated. RESULTS: The symptom intensity score in @entity392 was lower after getting up in comparison to later time points. In BVP a strong sensation of dizziness after getting up with worsening in the evening was observed. In @entity346 symptoms significantly improved during daytime. In BVP, the symptom intensity scores were significantly higher in @entity1 with symptoms more than six month as less than six month. In the other groups, no association between duration of illness and intensity of perceived dizziness could be seen. CONCLUSION: There are considerable differences in the change in symptoms between the three diseases. Taking the @entity1 history simply asking how the symptoms are when the @entity1 gets up in the morning and how they change during daytime can be helpful in the differential diagnosis. Having less or no symptoms after getting up may be a diagnostic criterion for @entity392 .

XXXX : Fewer symptoms in the early morning - a comparison with bilateral vestibulopathy and @entity346 .
