Vertigo can trigger migraines
Last Updated: 2009-09-03 16:11:02 -0400 (Reuters Health)
NEW YORK (Reuters Health) - Vertigo induced by vestibular stimulation can elicit migraines in susceptible individuals, according to researchers.
"One of the common causes of recurrent dizziness and vertigo is migraine," Dr. Adolfo M. Bronstein, of Imperial College School of Medicine, London, UK, told Reuters Health in an interview.
"In our paper we confirm that the relationship between migraine and vertigo is bi-directional," he said. "The specific finding is that the frequency of migraine attacks triggered by vestibular tests is much higher in patients with a previous history of migraine than in patients without previous migraine."
In a case-control study, Dr. Bronstein and colleagues examined prospectively whether vertigo induced by vestibular stimulation can act as a migraine trigger. A total of 123 new patients attending neuro-otology or neurology clinics were included in the study. The patients completed questionnaires and were interviewed by physicians to determine migraine history according to International Headache Society criteria.
Of the 123 patients, 79 underwent rotation/caloric vestibular testing (test group; 39 migraineurs and 40 non-migraineurs) and 44 did not undergo testing (control group; 21 migraineurs and 23 non-migraineurs). The main outcome measure was the occurrence of post-visit migraine, ascertained by a phone call or email to the patient the following day.
The findings are published in the August 25th issue of Neurology.
Of the 39 migraineurs in the test group, 19 (49%) experienced a migraine within 24 hours of testing, compared with 5 of 40 nonmigraineurs (12%) who had the vestibular tests and 1 of 21 (5%) migraineurs who were not tested.
Binary logistic regression analysis revealed an association between vestibular testing and migraine attacks. The onset of migraine occurred during the vertigo induced by vestibular testing in 47% of those who had post-visit migraine.
"Doctors will now have to be very careful when making a diagnosis of vestibular migraine (i.e., vertigo due to migraine)," Dr. Bronstein explained. "It may well be that, in some cases, vertigo of some other origin is triggering migraine rather than the other way round. Hence patients can go home with the wrong treatment."
"Now we have to establish a way of separating migraine-induced vertigo from vertigo-induced migraine," the researcher added. "For this we need to establish if, for instance, the course of events during an attack, or the examination of these patients, allows us to make a differential diagnosis efficiently."

I wanted to share this, I had problems with Vertigo for a long time when I was younger, and had auras...back then, doctors had no idea what was going on.
This many years later, I feel the way migraine is treated (should I say mistreated) we have a long way to go.
All the studies, breakthroughs, what does it matter when you go for help and are treated like you're crazy.
