Some studies suggest that people over age 50 are more likely to have symptoms of acephalgic migraine. When older people who have had migraines before get silent migraines, symptoms such asnausea, vomiting, and sensitivity to light and sound tend to diminish along with the headaches.Sex.Some research suggests that acephalgic migraines account for 3% of migraines in females and 1% in males.Genetics.Migraines often run in families. People who have family members who get migraines are often more likely to have some kind of migraine themselves.Thetriggersfor silent migraines are the same as those for other types of migraines and headaches and include:Certain foods (e.g., chocolate, artificial sweeteners) and drinks (e.g., caffeine, alcohol)Getting dehydrated and skipping mealsEnvironmental factors (e.g., lights, smells, sounds, weather changes)StressNot getting enough sleepHormonesCertain medications (including overusing medications that treat headaches)Diagnosing Silent MigrainesDiagnosing migraines without headaches can be tricky. A provider may need to use different tests to rule out other conditions.

One of the exams a provider will do can test a person’s brain and nerve function (neurologicalexam).It’s possible for a person to be mistakenly diagnosed withepilepsybecause the symptoms they get during a migraine attack and the results of their neurological exam can be similar.
