When you have long-term migraine, it's about much more than a headache. You may feel sick to your stomach or find it hard to handle light, sounds, and smells. For some people, though, it doesn't stop there. They also get something called an aura.
Most often, an aura causes you to see strange things, like colored spots or flashing lights. It can be scary, especially the first time it happens.
Migraines without auras are much more common than any other kind. You can get them as often as several times a week or as little as once a year.
Auras show up in about 1 in 3 people with migraine, but you're not likely to get them every time. So it's possible you might have both types of migraine, with auras happening here and there.
What Causes Migraines?
SPEAKER: Migraines can be
crippling, especially when they
come on unexpectedly.
Here are a few signs
that a migraine is coming
The first warning stage
for migraine, also called
the prodrome stage,
can happen anywhere
from a few hours to a few days
before the attack.
How can you tell?
You might be
irritable or depressed.
Or you could feel euphoria
or have excessive energy.
Some people yawn more.
And others feel an increased
urge to use the bathroom.
You might also crave things
like chocolate, cheese,
red wine, or beer.
You might have trouble
concentrating or sleeping,
and even feel tired or nauseous.
Your sensitivity to light,
sound, and odors might go up
during this stage.
The next warning stage, which
happens anywhere from five to 60
before a migraine attack,
is called the aura stage.
It can include seeing flashing
lights, zig zag lines,
or blind spots,
or hearing sounds or a ringing.
You may feel numbness
or tingling in your lips, face,
For people who get migraine,
keeping a journal can help you
track the warning signs you get.
If you watch for early signs,
you might be able to lessen
your migraine pain
Scientists aren't sure what causes migraines. They think many brain chemicals -- such as serotonin, calcitonin gene-related peptide, and dopamine -- play a role. According to the theory, a wave of nerve cell activity spreads across the brain and excites the trigeminal nerve. This causes the release of neurotransmitters that trigger a change in the size of blood vessels, releasing more neurotransmitters and finally causing an inflammatory process and pain.
Migraines often run in families. Other things can trigger migraine attacks for some people, like some foods, smells, stress, and things in the world around you. Changes in estrogen levels can lead to migraines for some people.
Migraines often begin in childhood and get worse through the teen years. More boys than girls have migraines, but more adult women than adult men have them. They usually happen less over time. Migraines become rare after age 50.
Although painful, a migraine is not life-threatening.
How Are They Different?
With or without an aura, you also get typical migraine symptoms, which may last 4 to 72 hours. They can include:
- Being sensitive to light, smells, sound, motion, and touch
- Blurred vision
- Pain that's usually on one side of the head and worse when you move
- An upset stomach and throwing up
- Stiffness in your shoulders and neck
When you get an aura, it typically sets in slowly over 5 to 20 minutes. It may last up to an hour. It often acts as a warning before any pain shows up. But it can happen during the migraine, as well.
Visual auras. These are the most common ones. You might see unusual shapes or effects that grow or move, such as:
- Blind spots
- Colored spots
- Flashes of light
- Sparkles and stars
- Tunnel vision
Other auras. Less often, they can affect your other senses and even your ability to move. You might have:
- Confusion and a hard time understanding people
- Movements you can't control, like sudden jerks
- Muscle weakness
- Music or noises in your head that aren't really there
- Pins and needles that start in your fingers or arm and spread to your face
- Speech problems, as if you know what you want to say but can't form the words
It’s important to remember that these can also be symptoms of a stroke. If you have any of them and your doctor has not told you before that they are a part of your migraine, call 911.
Sometimes, you can get an aura without any other symptoms. That's sometimes called a silent migraine. It's more common in people 50 and older.
Do I Need Different Tests?
With any kind of migraine, your doctor may ask you things like:
- Do other people in your family have migraines or other kinds of headaches?
- Do you have any allergies?
- What is the level of stress in your life?
- Do you use medications such as birth control pills or vasodilators that could cause headaches?
- Do you notice that headaches start after coughing or sneezing or after intense exercise?
They’ll do tests to check for other conditions that could cause your symptoms. You may have blood or imaging tests, like a CT or MRI.
Symptoms of a migraine with aura can look like a more serious condition, such as a stroke or a seizure. To rule those out, you may get some extra tests, including an eye exam. You might also be more likely to have imaging tests.
The first time you notice an aura, it's important to get medical care right away to find out what's going on.
Once you've made sure there are no other issues, you don't need to see your doctor every time you have that same aura. But if your symptoms change, make sure to check in.
Are They Treated Differently?
Not really. Experts aren't sure what causes auras, so there's nothing special you can do about them. It's about treating the migraine symptoms and preventing more attacks.
To ease migraine symptoms:
- Stay in a quiet, dark room.
- Put cold compresses or pressure on the painful areas.
- Take pain-relieving medications such as aspirin, acetaminophen, ibuprofen, ketorolac, or naproxen. People under the age of 19 should not take aspirin.
- Use prescription drugs, such as almotriptan (Axert), eletriptan (Relpax), frovatriptan (Frova), lasmiditan (Reyvow), naratriptan (Amerge), rizatriptan (Maxalt), and sumatriptan (Imitrex, Onzetra Xsail, Sumavel DosePro, Tosymra, Zembrace SymTouch), which help narrow blood vessels.
- Ergots (Cafergot, Migergot) and gepants (Nurtec, Ubrelvy) may also ease migraine pain.
- Use medications to treat other migraine symptoms such as nausea and vomiting.
SPEAKER: While there's no cure
there are treatments that can
ease your symptoms
and help keep future attacks
Pain relieving drugs can be
taken during migraine.
Many are over-the-counter.
They come as pills,
nasal sprays, or shots.
And they work best when taken
at the first sign of a migraine.
And if your migraines come
with nausea and vomiting,
anti-nausea drugs can also help.
treatments are another option.
You take these drugs regularly
to lessen how often you get
and how severe they are.
Some preventive options are
blood pressure-lowering drugs,
anti-seizure drugs, Botox shots,
and CGRP receptor blockers.
or with other treatments,
lifestyle changes, home
remedies, and non-traditional
therapies can also provide
You could try acupuncture, yoga,
or behavioral therapy.
Put yourself on a sleeping
and eating routine,
exercise often, and be
sure to drink plenty of water.
Not all treatments work
for everyone, but with so many
options, you and your doctor
can find the best plan for you.
To prevent migraines:
Medications. If other treatments don’t work and you have 4 or more migraine days a month, your doctor may suggest preventive medicines. You take these regularly to make headaches less severe or less frequent. They include seizure medicines, blood pressure medicines (like beta-blockers and calcium channel blockers), and some antidepressants. CGRP inhibitors are a new class of preventive medicine that your doctor may recommend if other medicines don’t help.
Devices. Cefaly is a portable headband-like device that sends electrical impulses through the skin of the forehead to stimulate a nerve linked with migraine headaches. You use it once a day for 20 minutes. When it's on, you'll feel a tingling or massaging sensation. SpringTM or eNeura sTMS may be another option. You hold this device at the back of your head at the first sign of a headache, and it gives off a magnetic pulse that stimulates part of the brain. In addition, a noninvasive vagus nerve stimulator called gammaCore releases a mild electrical stimulation to the nerve's fibers to relieve pain. Some of these devices may also treat migraines after they start.
Keep a headache diary. It will help you spot things that might trigger your migraines. Diary entries should include things like the date and time of your headache, any foods you had eaten, what you did, and medication you took just before the headache began. It may take 6 to 8 weeks or longer to begin to see patterns and triggers.
Avoid common food triggers. Use information from your diary and from trial and error to figure out if any of these foods might be causing your migraines:
- Red wine or other types of alcohol
- Citrus fruits
- Artificial sweeteners
- Food preservatives, such as nitrates, nitrites, and monosodium glutamate (MSG)
- Ice cream or other cold foods
Avoid medication triggers. Many over-the-counter and prescription drugs can bring on migraines. Check with your doctor if you think any of these may lead to your headaches:
- Birth control pills and hormone therapy
- Hydralazine (Apresoline)
- Nifedipine (Procardia)
Never stop taking a medication unless your doctor tells you to.
Relieve mental or emotional triggers. Stress, depression, anxiety, and strong feelings such as grief can trigger migraines. Although you can’t always avoid these things, you can learn to control how you handle them. Relaxation, biofeedback, and self-hypnosis techniques can help relieve these sources of stress and prevent migraines, especially in children.
Reduce physical triggers. Illnesses, fatigue, and missing meals can all trigger migraines. So can overdoing exercise, motion, and head injuries. Even menstruation can set off migraines. Know how these things affect you, keep a regular routine, treat illnesses quickly, and take steps to avoid other physical triggers.
Look for environmental triggers. Some people are sensitive to flickering lights, fluorescent lights, changes in air pressure or altitude, or even bold visual patterns. Use your headache diary to spot any possible triggers in your environment -- and then take steps to get rid of them or avoid them.
Migraine and Stroke
Migraine with aura slightly raises your chances of getting a stroke. This is especially important to know for women who take birth control pills, get hormone replacement therapy, or smoke, since these things can raise your odds even more.
If you have migraine with aura, work with your doctor to understand how you can lower the chances you'll get a stroke. And keep in mind that an aura usually goes away when the migraine shows up. If it lasts more than an hour, get medical help right away.
