Mine is there all the time but absolutely gets worse with triggers and varies like clockwork to my monthly cycle. I went out yesterday feeling sick and the car ride made me worse not better. I get times when I’m in the car where I feel like I’m hurtling through space 200 miles an hour while the car is moving and then when it stops I still feel that way and if I try to get out and walk, everything bounces, spins, and my body goes flying forward. It was a Valium kind of day yesterday.
I can see what you mean now about the symptoms overlapping, but with MdDS being there all the time, MAV could also be there all the time but with some people like me, if you have things that trigger it, it can get worse and then get a little better, wax and wane if that makes sense. It says also that MdDS symptoms can vary in severity but it’s not known why, maybe different stress levels.
Examples of things that make mine worse are fluorescent lights, computer, certain migraine trigger foods, being overheated, not getting enough sleep, movement like being in the car or a busy store etc.
It says that the DX is made after all other reasons for it are eliminated, so when my doctor’s found out I did have migraine/MAV, that’s probably why they never even considered this.
Here is some info that I copied and pasted from MdDs foundation site. I think the symptoms NOT typically seen is helping in comparing because I have all of them.

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 increased symptoms with stress, fatigue, illness, dark rooms, bright lights, busy patterns, shopping in malls and grocery stores, and walking in crowds. For many, the symptoms decrease over time, but not always.
Additionally, some sufferers have experienced recurrence of symptoms triggered by events such as subsequent cruises, air travel, upper respiratory infections and other motion experiences such as elevator rides, etc.
PLEASE NOTE: Many of these symptoms can be experienced by those with other inner ear disorders. This is why MdDS is usually diagnosed after eliminating other disorders and by patient history that may include a recent cruise, boat, car or plane ride or other motion experience.
