I’ve read on some other sites about a condition – possibly related to migraine – called Cyclic Vertigo. It apparently occurs in young people before age 21 and they have vertigo attacks on a regular basis — like once every 24 or 25 days.
The people then go on to develop “regular” migraine when they are in 20’s or 30’s.
My vertigo attacks are fairly regular but not always by any means and I am not in that age category by any means. However, I was quite interested in this symptom.
Some young people have nausea instead of the vertigo attacks on a regular basis.
I’m so curious about this. Why does it occur in cycles? Does some chemical accumulate in the body? I have not found out very much on this.
