migraine complications awareness

Overview

A migraine is a common brain condition that causes intense headaches, often with nausea, vomiting, and sensitivity to light and sound. Most migraines are temporary and get better on their own or with care. But sometimes migraines can lead to complications — health problems that happen because of the migraine itself. This article helps you understand those rare complications and what to watch out for.

Migraine itself is very common — about 1 in 7 people worldwide have it. But complications of migraine are uncommon. Most people who have migraines do not develop any complication.

Anyone who gets migraines can have a complication, but they are more likely in people who have migraine with aura, in women, and in people with other health conditions like high blood pressure or diabetes. Children and older adults can also be affected, but complications are rare in all ages.

Symptoms

Common symptoms

• Throbbing headache, usually on one side of the head
• Nausea or vomiting
• Sensitivity to light, sound, or smells
• Blurred vision or seeing zigzag lines (aura)
• Dizziness or feeling light-headed
• Trouble concentrating

Symptoms in children

• Children often have shorter migraines than adults
• They may have stomach pain with headache or stomach ache alone (abdominal migraine)
• They may look pale, feel dizzy, or want to lie down in a dark room
• Vomiting during a migraine is more common in children

Symptoms in older adults

• Migraine with aura can sometimes look like a stroke, with weakness or numbness on one side
• Older adults may have new headache types that need quick medical attention
• Balance problems or confusion during a migraine may be a sign of a complication
• A sudden severe headache after age 50 should be checked by a doctor right away

Causes

Main causes

• Migraine is a brain disorder that involves nerve pathways and brain chemicals — not a sign of weakness
• Complications usually happen when a migraine attack is very severe or lasts a long time
• Changes in blood vessel tone during a migraine can sometimes reduce blood flow, which might lead to a stroke in rare cases
• Persistent aura (vision or other symptoms that last for weeks) can happen because the brain's electrical activity stays altered

Risk factors

• Having migraine with aura
• Being female
• Using hormonal contraceptives or hormone replacement therapy, especially if you smoke
• Smoking
• High blood pressure or high cholesterol
• Having a family history of migraine or stroke
• Older age for stroke-related complications

When to see a doctor

See a doctor urgently if:

• Any new weakness, numbness, speech problem, or vision loss during or after a headache
• A migraine headache that lasts more than 72 hours
• A sudden, severe headache different from your usual migraines
• Headache with fever, stiff neck, confusion, or seizure

Book a routine appointment if:

• Migraine attacks that interfere with your daily life or make you miss work or school
• Your migraine pattern changes — for example, they become more frequent or more intense
• You need to take pain relievers more than two days a week
• You want to discuss preventive treatment with a healthcare provider

Diagnosis

A healthcare provider will ask about your symptoms, medical history, and family history. They will also do a physical exam, and sometimes a neurological exam to check your reflexes, strength, and balance. There is no single test for migraine; the diagnosis is based on your pattern of symptoms.

Tests that may be done

• An MRI scan to take detailed pictures of the brain
• A CT scan to check for bleeding or other problems
• Blood tests to rule out infections or other conditions
• An eye exam if you have vision symptoms

What to expect at your appointment

Your provider may ask you to keep a headache diary to track when migraines happen, how long they last, and what triggers them. They may also refer you to a neurologist — a doctor who specializes in brain and nerve conditions. You may need tests to rule out other causes of your symptoms, but most people with migraine do not need extensive imaging.

Treatment

Treatment for migraines aims to stop an attack when it happens, reduce how often attacks occur, and address any complications quickly. Your healthcare provider will tailor your plan to your specific symptoms and situation. Always follow your provider's advice about what to do for a migraine attack.

Self-care at home

• Rest in a quiet, dark room
• Place a cool or warm cloth on your forehead or back of your neck
• Drink water to stay hydrated
• Avoid bright screens, strong smells, and loud noises
• Try relaxation techniques like deep breathing or meditation
• Sleep not too little and not too much

Medical treatments

Medicines for migraine come in two main groups: acute treatments that you take when a migraine starts, and preventive treatments that you take regularly to reduce the number of attacks. Acute treatments include simple pain relievers, anti-nausea medicines, and prescription medicines that target migraine pathways. Preventive treatments include blood pressure medicines, antidepressants, and seizure medicines — these are used even if you do not have high blood pressure, depression, or seizures. There are also newer treatments that are given by injection. Your healthcare provider will decide which option may be right for you. Never take more than the recommended amount of any medicine without speaking to your provider.

When is surgery considered?

Surgery is not a standard treatment for migraine or its complications. In very rare cases, a procedure called a nerve block may be used for severe attacks, but this is not surgery. Always ask your healthcare provider about any invasive treatment.

Living with this condition

Living with migraines involves learning your triggers and making a plan for when an attack hits. Keep your medicines with you, know your warning signs, and inform your family, friends, and employer about your condition. You can still live a full life with migraines.

Lifestyle tips

• Try to sleep and wake at the same time every day
• Eat regular meals and don't skip meals
• Manage stress with yoga, mindfulness, or counseling
• Keep a migraine diary to spot patterns
• Limit caffeine and avoid alcohol if it triggers your migraines

Diet and exercise

A balanced diet with enough water can help. Some people find certain foods like aged cheese, chocolate, or processed meats trigger attacks, but triggers vary from person to person. Regular exercise like walking, swimming, or cycling can reduce migraine frequency, but start slowly to avoid triggering a headache from sudden exertion.

Mental health and emotional wellbeing

Living with chronic pain can increase stress, anxiety, and depression. It's normal to feel frustrated or worried. Talking to a counselor or mental health professional can help. If you ever feel hopeless or have thoughts of self-harm, please reach out to a crisis support service right away — your local emergency number or helpline can connect you with help.

Prevention

Migraine itself cannot be cured, but you can reduce the number of attacks and lower your risk of complications. Preventive treatments, regular sleep, exercise, and stress management all help. If you have migraine with aura, your provider may also talk to you about avoiding certain hormonal contraceptives and stopping smoking to lower stroke risk.

Complications

If left untreated

• Status migrainosus — a severe migraine attack lasting more than 72 hours that can cause dehydration and exhaustion
• Persistent aura without infarction — aura symptoms like visual changes that last for weeks, without causing permanent brain damage
• Migrainous infarction — a stroke that happens during a migraine attack, with headache and stroke-like symptoms; this is very rare
• Complications from medicines — for example, overusing pain relievers can cause medication-overuse headache

Long-term outlook

The outlook for people with migraine is generally reassuring. Complications are rare, and most migraines do not cause long-term harm. With good medical care, self-care, and healthy habits, most people can keep their migraines under control and live a healthy, active life. If you ever worry about a complication, talk to your healthcare provider — they are there to help you.
