Almost 40 million individuals within the U.S. undergo from migraines, making the painful dysfunction one of the crucial widespread that neurologists deal with. It’s additionally among the many most complicated. Due to the various methods it may well present up, it may well take greater than a decade to obtain an correct prognosis.
“The final idea about migraine within the widespread inhabitants is that it’s a headache syndrome,” says Dr. Hamid S. Hamdi, a neurologist who leads the Headache Clinic at UTHealth Houston Neurosciences in Sugar Land, Texas. And positively, many migraine victims—although not all—expertise a throbbing headache. Past that, nonetheless, “individuals don’t learn about all the opposite signs that migraine may cause, in order that they’re very shocked to start with,” he says. “Whilst neurologists, we don’t at all times write off all of the signs to migraine till we’ve dominated out issues like a stroke.”
We requested Hamdi and different neurologists which non-headache migraine signs they see most frequently.
Meals cravings
About two to a few days earlier than creating a headache, individuals sometimes enter the prodrome (early) part of a migraine. Signs embody irritability and different temper modifications, fatigue and bother sleeping, issue concentrating, neck ache, and hyperactivity.

Some individuals expertise imaginative and prescient modifications with each headache, he provides, whereas others report these signs solely accompany a portion of their complications.

You may recall the clip of a TV reporter that went viral greater than a decade in the past, when the journalist abruptly turned incoherent—leaving many watching at dwelling frightened she was having a stroke.

Somebody with aphasia might need issue forming full sentences, as a substitute repeating jumbled phrases, or will begin slurring. “We see this on a regular basis within the emergency division, and we’ll undergo an analysis, ensuring it’s not one thing like a stroke,” Bravo says. Docs typically do imaging exams akin to CT scans or MRIs earlier than concluding—usually by means of elimination—{that a} affected person is experiencing a migraine.

That additionally contains gentle contact in your scalp from brushing your hair, the feeling of rubbing a blanket over your physique, or feeling a breeze brush towards your pores and skin.
Motor modifications
Hemiplegic migraines—that are uncommon however severe—are related to motor modifications, like one-sided physique weak spot or paralysis.
