For years I've been dealing with a mysterious problem. Years of frustration. Years of not knowing what the heck is wrong.
I get SILENT MIGRAINES!!!!!! What the.....never have heard of that but I finally have figured out what is going on. A nurse - of ALL people told me I had migraine aura. Doctors couldn't figure it out....it was the nurse!!!!! I had a horrendous silent migraine today. No headache just all the crazy symptoms. Today I was dealing with horrendous vertigo, nausea, pressure in my back/head/neck/eyes, weird eye spots and an overall pain. I always forget what is going on with me and then "duh...migraine." Easily fixed with an Advil migraine pill. Ugh! At least I know!

Silent migraine is one name for a type of migraine attack that doesn't include a headache. As strange as it may sound, it's actually not all that unusual. Over the years, silent migraine has gone by other names, including acephalgic migraine, sans-migraine, migraine equivalent, eye migraine, visual migraine, ocular migraine, painless migraine or simply migraine aura without headache. Today it's usually called migraine aura without headache.
Migraine aura is a term used to describe many of the other symptoms that go along with migraine, but it's usually referring to visual symptoms. This might include seeing zig zags or flashing lights, or having dizziness or vertigo. It's estimated that only about 15% of migraineurs deal with aura. There are actually a host of possible symptoms that can hit, usually before a headache stage, such as slurred speech, numbness, pain in other parts of your body such as in the face or on the skin, and ringing in the ears.
Interestingly, migraine aura without headache more often occurs later in life, and more often in men than in women.
As you may imagine, with so many symptoms in silent migraine, it's prone to misdiagnosis. Sure, if you were to get a one-sided headache, or any headache, migraine might be suspected. But without the headache stage, the migraine diagnosis is often missed.
I recently read an article by a patient who was first told he had had a mini-stroke, then he was diagnosed with things like hypoglycemia, meniere's disease (an inner ear disorder), depression, fibromyalgia and myofascial pain! It's easy for silent migraine to be mistaken for many other diseases - and that's no help to the patient.
Even those who get "normal" migraine can get silent migraine from time to time. It's estimated that 20% of migraineurs have had a silent migraine. Of course, it's easier for someone with a history of migraine to recognize the symptoms.
Silent migraine has not gotten a lot of specific press, probably because it's often simply lumped in with other migraine. Most of the migraine books I own don't specifically mention it in the index by any name, although they do talk about it here and there. This can make it pretty frustrating for the patient looking for information.
