MRI for Migraines and Headaches

Introduction

Did you know migraines have become common? Even kids can get them, too! A migraine is a strong headache that can make anyone feel sick. But sometimes, people don’t know they have a migraine because they never get diagnosed. Doctors usually figure out if someone has migraines by asking about their symptoms and medical history and doing a check-up. Most of the time, a brain MRI (magnetic resonance imaging) isn’t needed, but in some cases, doctors might suggest getting one. This article explains why an MRI might help find out more about migraines and what doctors look for in the images.

When Is an MRI Recommended for Headaches or Migraines?

Doctors may use an MRI scan if:

• The headache starts happening in a new or different way.

• The headache comes with other problems like blurry vision, confusion, dizziness, or weakness.

• Older people or people with weak immune systems get headaches.

• The headache gets worse when coughing or running around.

• Someone has headaches all the time (chronic headaches).

• The doctor thinks something in the brain might not look right.

• A headache comes with an aura (like seeing flashes of light) that lasts more than an hour.

• A different test, like a CT (computed tomography) scan, doesn’t show what’s causing the headache.

What Can an MRI Detect?

An MRI is a special machine that takes pictures of the inside of the body, like the brain and spine. It can help doctors find different problems, such as:

• Tumors.

• Stroke (when blood can’t reach part of the brain).

• Brain injuries.

• Aneurysms (bulge in the blood vessel).

• Hemorrhages.

• Blocked blood vessels.

• Vascular malformations (problems with blood flow).

• Joint injuries.

• Soft tissue injuries.

• Damage to internal organs.

• Herniated discs.

• Hydrocephalus (fluid buildup in the brain).

Doctors choose the best type of scan based on what they need to see:

• MRI: Shows soft tissues (like muscles and organs) in great detail. It uses magnetic and radio waves. And there is no radiation!

• CT Scan: It is best for looking at bones, finding internal bleeding, and spotting hard tissue problems. It does use some radiation.

• MRA (Magnetic Resonance Angiography): This helps doctors see blood vessels and how blood is flowing in the body.

Is an MRI Safe?

Yes! An MRI is usually very safe because it doesn’t use radiation. But in some cases, doctors might not recommend it, such as:

• If someone has metal inside their body, like a pacemaker or metal implants.

• If a person is scared of small spaces (claustrophobia). In these cases, they can try relaxing, or the doctor might give them medicine to help them stay calm.

• If they are allergic to the special dye (contrast agent) used in some MRIs.

• If they have kidney problems.

How to Prepare for an MRI Scan?

If you ever need an MRI scan, here’s how to get ready:

• Take off all metal things! That means no necklaces, rings, or watches. Even things like braces, hearing aids, or wigs with metal have to go!

• You can eat and drink like normal! But if the doctor says you need a special liquid (called contrast), you might have to wait 4 to 8 hours before eating. Contrast dyes are used to enhance the images. The contrast agent may be injected or given by mouth.

• Tell your doctor if you’re pregnant, have allergies, feel scared in small places, or have any metal inside your body.

An MRI can be super quick (15 minutes) or take a little longer (1 hour). An MRI can be super quick or take a little longer!

What Happens During and After an MRI?

During:

• An MRI is like a big tube, and you have to lie down inside it.

• Before your scan, take off anything metal. If the doctor is using a special dye (contrast), you might need to stop eating or drinking for a little while.

• You might hear loud tapping noises, but don’t worry; it won’t hurt at all!

After:

• You might need to wait a little while so the radiographer can check the pictures.

• If you take medicine (sedatives) to help you relax, you might need to rest and not drive.

• Most of the time, you can go back to your normal activities right away!

Can MRI Show Signs of Migraine?

In certain individuals with migraine, an MRI scan of the brain might show white spots or regions. Lesions or irregular areas in the brain's white matter are to blame for these. Everybody has some little brain injuries, and they are a typical piece of aging or maturing. They can occur when blood flow to a small portion of the brain is reduced or stopped. Lesion-causing damage to some brain cells may result from this. The reason why migraine sufferers develop these lesions is unknown to researchers. These lesions appear to be more normal in individuals who experience migraines with aura.

Some people may develop more lesions than usual as a result of chronic or severe migraine. Be that as it may, white matter injuries do not cause migraine side effects. Researchers say that they are likewise not connected to dementia or cognitive decline in older adults.

Clinical researchers use MRI scans of the brain to assist in figuring out why the episodes of migraine might occur in certain individuals and not in others. In one study, researchers investigated how stimulation of the senses of sight, smell, and pain affected the brain. They discovered that migraine sufferers may have abnormal or more sensitive brain responses to everyday stimuli.

What Is the Outlook for Migraine-Related MRI Findings?

Migraine is a typical and treatable sort of headache. Be that as it may, it is commonly long-lasting and ongoing. The majority of migraine sufferers experience episodes that last about four hours. A single migraine episode can last anywhere between a period of 72 hours to a week if not treated. A specialist might attempt one or two prescription medicines to find the one that suits every individual. Nonsteroidal anti-inflammatory drugs (NSAIDs), which are available over the counter, are the first line of defense in the treatment of migraines for some people. If the patient can identify the migraine triggers, making lifestyle changes and avoiding them may also be helpful. Changes that could alleviate migraine pain may include:

1. Maintaining good sleep hygiene.

2. Having a regular exercise routine.

3. Having adequately balanced meals.

4. Avoid eating processed foods.

5. Limiting screen time.

Conclusion

A common cause of headache pain with a variety of symptoms is migraine. Experts are not exactly sure what causes migraines or why some people get them. A magnetic resonance imaging (MRI) scan may or may not be necessary for migraine diagnosis. Researchers can also use these brain scans to learn more about migraines and how they affect the brain. Hopefully, this will pave the way for the development of new migraine treatments and prevention strategies in the future.

Key Takeaway From iCliniq

Migraines can be very tough! But knowing what causes them can help you manage them better. An MRI can’t determine if one has migraines, but it can be super helpful in ruling out other conditions that can cause headaches. So, if headaches keep bothering you, don’t worry; doctors at iCliniq have ways to figure things out and help you feel better!
