Some medics say MAV is an offshoot, Vestibular Migraine slightly more specific. According to official criteria patient has to meet n different criteria to âqualifyâ for VM otherwise they go into the MAV bucket. Not that it makes much difference. Treatments are the same. Indeed some neuros mutter about âmigraine spectrumsâ to keep it even vaguer. But whichever shouldnât affect husbandâs treatment so do not worry.
