Is a hypersensitivity to odors a symptom of a migraine attack or a trigger for an attack?
Those with migraine usually have a heightened sense of smell. This hypersensitivity to odors can be both a trigger and a symptom of a migraine attack.
“... people with migraine unfortunately have this hyperactivity to odors. Odors, certainly like light and sound can both be a trigger for migraine attacks, as well as a symptom of the attack itself. There are certain smells that, you know, that individuals might find more bothersome than others. Things like perfume, cigarette smoke, these are very commonly cited odors that are particularly bothersome to individuals.”
