What Is Migraine With Aura?
Migraine with aura is a condition that usually includes intense headaches along with sensory disruptions like dizziness, ringing in your ears, zigzag lines in your vision, or sensitivity to light.
About a quarter of migraine attacks include these sensory changes, called auras. But you may not have one with every attack. Some people get an aura but no head pain.
Though they can hurt a lot and make you feel "off," these headaches aren't life-threatening. Lifestyle changes, medications, and devices can treat the symptoms and sometimes prevent a migraine headache with aura.
Auras can affect your vision, hearing, or ability to speak. You could also have muscle weakness or a tingling sensation.
Types of Migraine With Aura
You can get auras with several types of migraine:
Migraine aura with a headache. With this type, you have aura symptoms shortly before or at the same time as a migraine headache. You might hear it called "classic migraine," although most people with migraine don't get auras.
Migraine with a brainstem aura. This is when the aura starts in the base of your brain (brainstem) or on both sides of your brain. This type includes neurological symptoms like slurred speech, dizziness, ringing in the ears, and double vision.
Hemiplegic migraine. With this rare type, the aura causes weakness on one side of your body (hemiplegia).
Retinal migraine. You have vision changes in one eye before the headache begins.
Migraine aura without a headache
This type of migraine attack includes symptoms of an aura such as dizziness or vision changes but no headache. Also called silent migraine, it's relatively rare, affecting only about 4% of those with migraine. Some people who have migraine with aura stop having headaches as they age but keep having auras.
Migraine With Aura vs. Ocular Migraine
Ocular migraine is another term for retinal migraine. Like some other types of migraine with aura, it involves changes in your vision. But it affects only one eye. Its visual symptoms tend to not last as long as those of other types of migraine with aura. Your head pain may also be concentrated behind the eye in which you have aura symptoms.
Ocular migraine isn't common. But it can be serious. If you don't get treatment, there's a small chance that the vision loss in one eye could become permanent.
In an ocular migraine attack, a change in vision can happen in one eye before, during, or after a headache. The symptoms include:
- Seeing twinkling or sparkling lights
- Having blind spots
- Temporary blindness
One way to tell if the vision changes are only happening in one eye is to close each of your eyes and check if you only see the changes in one of them.
Migraine With Aura Symptoms
What does migraine with aura look like?
Auras may seem like a warning sign that a migraine headache is coming. They often start 30-60 minutes before the headache begins.
In most cases, aura symptoms come on gradually over a span of about 5 minutes. They can last up to an hour.
The most common symptoms are visual ones, such as flashing lights or blind spots.
Prodrome symptoms of migraine with aura
Some 40%-60% of all people with migraine have warning signs 24-48 hours before an attack. This is called the prodrome or preheadache phase. It's not the same as an aura, but you can have prodrome symptoms before a migraine headache with aura. During prodrome, you may:
- Crave certain foods
- Feel hyper or cranky
- Be tired and yawn more
- Feel stiffness, especially in your neck
- Need to pee more often
- Get constipated or have diarrhea
Symptoms of a visual aura
Light may sparkle across your eyes. It may seem like a bulb is flickering. You may notice jagged lines that look like a horseshoe that gets bigger. That's called a fortification spectrum. You may get something called Alice in Wonderland syndrome. When this happens, your body parts may seem distorted, or you might feel like a big person in a small room.
Common visual aura symptoms include:
- Flashes of bright light
- Foggy or blurry vision
- Zigzag lines
- Blind spots (scotoma)
- Partial loss of vision
- Small, bright dots
- A field of vision that looks like a heat wave or water
- Colored spots
Sometimes, you may have:
- Trouble judging distances
- Fractured vision, like looking through broken glass
- Visions of things that aren't there (hallucinations)
- Tunnel vision
- Short-term blindness
Symptoms of a sensory aura
A sensory aura starts as a prickling, tingling, or numb feeling in your arm or leg. The feeling gradually travels up your limb and can spread to your face or tongue. You can have this along with visual aura symptoms.
Symptoms of a dysphasic aura
Dysphasic aura is a rare type of migraine aura in which you have trouble talking. You may not be able to say the right words. Or your sentences may not make sense. You might not be able to understand what people say.
Symptoms may include:
- Trouble finding words or speaking (aphasia)
- Mumbling
- Slurred speech
Any of these symptoms could also be a sign of a stroke. If you have new symptoms that are different for you, call 911 and get help right away.
Other symptoms
Migraine pain can be steady or throbbing. You usually feel it on the front or side of your head, around your eyes. Adults are more likely to have pain on just one side. It is a long-lasting headache and may last a few hours up to 3 days.
Besides pain, your symptoms may include:
- Upset stomach or vomiting
- Hot flashes and chills
- Stuffy or runny nose
- Dizziness or spinning (vertigo)
- Sore neck or jaw
- Sensitivity to light, sounds, smells, touch, or motion
- Confusion
- Muscle weakness
Migraine With Aura Causes
Scientists aren't sure what causes migraine, but several brain chemicals probably play a role.
According to this theory, an attack starts when a wave of nerve cell activity leads to changes across your brain and triggers your trigeminal nerve. This causes the release of a variety of neurotransmitters (chemical "messengers" within your nervous system) that change the size of blood vessels, release more neurotransmitters, and finally cause inflammation and pain.
Experts think the aura happens because of this electrical wave moving across the part of your brain that processes signals from your senses.
Migraine often runs in families. It often begins in childhood and gets worse through adolescence. Although more boys than girls have migraine, more adult women than men have them. Over time, you'll probably have fewer, and they become less common after age 50.
How common is migraine with aura?
About 25%-30% of people with migraine have auras.
Aura Migraine Triggers
For many people, certain substances or situations can bring on a migraine attack. Common triggers for migraine headaches with or without aura include:
- Certain foods like cheese or chocolate or food additives like nitrates
- Alcohol
- Medications
- Stress
- Being tired, sick, or hungry
- Period
- Bright, flickering, or flashing light
- Air pressure or altitude changes
- Changes in your sleep schedule
- Sex
- Neck pain
- Smoke
- Heat
- Changes in your caffeine intake
- Strong odors
- Loud noise
- Exercise
A headache diary can help you and your doctor figure out what might be setting off your attacks. Note the date and time of the attack, any food you had eaten, what you were doing, and any medication you took before the headache began. It may take several weeks before you notice a pattern.
Migraine With Aura Diagnosis
Your doctor will do a physical exam and check your muscles, reflexes, speech, and senses. They'll likely ask questions about your symptoms and health history, such as:
- Do other family members have migraine or other kinds of headaches?
- What medications do you take, including birth control pills or blood pressure drugs?
- Do your headaches start after you work hard, cough, or sneeze?
Your doctor may do an eye exam to check whether vision issues might be causing your aura symptoms. Imaging tests like CT scans and MRIs can help rule out other possible causes of aura symptoms such as a transient ischemic attack (ministroke).
Migraine With Aura Treatment
Medications known as acute or abortive medications work quickly to stop migraine pain.
Over-the-counter pain relievers like acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, or naproxen may help, especially if you take them at the first signs of an aura. Your doctor can prescribe larger doses of NSAIDs. (No one under the age of 19 should take aspirin without a doctor's approval.) Be careful about using pain relievers too often, as this can lead to "rebound" headaches when they wear off.
Other migraine-specific medications require a prescription. They include the triptans and ditans, such as almotriptan (Axert), eletriptan (Relpax), frovatriptan (Frova), lasmiditan (Reyvow), naratriptan (Amerge), rizatriptan (Maxalt), and sumatriptan (Imitrex). Ergots (Cafergot, Migergot) and calcitonin gene-related peptide (CGRP) antagonists such as rimegepant (Nurtec ODT) and ubrogepant (Ubrelvy) may also treat migraine pain.
You can also take medications to ease nonheadache symptoms such as nausea and vomiting. Magnesium supplements may help with both aura symptoms and head pain.
Some nerve stimulation devices are designed to short-circuit a migraine attack by turning on your brain in a particular way. Some are handheld, and others are wearable. Some can also be used to prevent migraine attacks.
These devices include:
- External trigeminal nerve stimulator (Cefaly), available over the counter
- Noninvasive vagal nerve stimulator (gammaCore Sapphire), available by prescription
- Single-pulse transcranial magnetic stimulator (SAVI Dual), available by prescription
- Remote electrical neuromodulator (Nerivio), available by prescription
Migarine With Aura Prevention
If other treatments don't work and you have migraine attacks on 4 or more days a month, your doctor may suggest preventive medicines. You take these regularly to make your headaches less strong or happen less often.
They include seizure medicines, blood pressure medicines (like beta-blockers and calcium channel blockers), and some antidepressants. A new class of preventive medicine called CGRP monoclonal antibodies may also help. You take them as a shot.
Getting injections of the botulinum toxin (Botox) every 3 months can also help prevent attacks.
Living With Migraine With Aura
Figuring out your migraine triggers and avoiding them can help you have fewer attacks. It may also help you:
- Stick to a regular schedule for meals and sleep
- Make sure you stay hydrated by drinking plenty of fluids
- Use stress-reduction techniques such as meditation or yoga
- Get regular exercise
- Use good posture to prevent neck strain
What to do when a migraine headache with aura hits
As soon as you notice symptoms of migraine with aura, take any medication you use and lie down in a quiet, dark room. Try putting a cold compress or heating pad on tight or painful areas.
Migraine With Aura Complications
Migraine with aura can be painful and interfere with your daily life, but it doesn't usually cause serious health complications. In rare cases, it could lead to:
Seizures. It's possible to have an epileptic seizure that's triggered by an attack of migraine with aura. It usually happens within an hour of the migraine attack. You might hear this called "migralepsy."
Stroke. A stroke linked to migraine is called a migrainous stroke. It's more likely to affect people who have migraine with aura than those whose attacks don't include auras.
Long-lasting aura. You could have an aura that lasts more than a week after your headache ends.
Status migrainosus. This is when a migraine attack lasts longer than 72 hours. You may need to go to the hospital if this happens.
Other Causes of an Aura
An epilepsy aura is sometimes called a focal aware seizure. Symptoms may only last a few seconds to several minutes. But it can be a sign that a more serious seizure is about to happen. You may get it before you faint. If you know what to look out for, you may be able to get somewhere safe before your seizure starts.
Symptoms of an epilepsy aura include:
- A feeling of déjà vu
- An uneasy feeling in your stomach
- A weird taste or smell
- A strong sense of joy or fear
- Numbness or pain in your head or limbs
- Dizziness
- Nervousness
- Nausea
You'll need to prevent your seizures to stop the auras. Your doctor can help you find the right treatment. They may give you medicine. In some cases, you may need nerve stimulation or surgery. If other treatments fail, your doctor may suggest a special diet.
A migraine with aura attack can come before a stroke. But it happens in less than 1% of all strokes. Experts aren't sure why this happens. They do know that you're more likely to have a stroke if you have a history of migraine with aura. It's also more common in women who are 45 or younger. That may be because of hormonal changes. Hormonal birth control also raises the chances you'll get blood clots.
You should look for signs of an aura mixed with stroke symptoms, including:
- Numbness or weakness on one side of your body
- Confusion
- Trouble talking, seeing, or walking
- Dizziness or loss of balance
- A really bad headache
You may be able to lower your chances of having a stroke if you:
- Treat your high blood pressure
- Manage your diabetes
- Lower your high cholesterol
- Exercise on a regular basis
- Don't smoke
Always call 911 if you think a loved one is having a stroke. They need medical attention right away.
Takeaways
Migraine with aura is when your migraine headaches come with sensory changes like blurred vision, ringing in the ears, or dizziness. While it doesn't usually cause serious health complications, it can be very painful and interfere with your daily life. The right treatment can help prevent or stop these attacks, so see a doctor if you have symptoms of migraine with aura.
