Diagnosis and Treatment of Migraine Headache

Diagnosis

If you have migraines or a family history of migraines, a doctor trained in treating headaches (neurologist) will likely diagnose migraines based on your medical history, symptoms, and a physical and neurological examination.

If your condition is unusual, complex or suddenly becomes severe, tests to rule out other causes for your pain might include:

• Magnetic resonance imaging (MRI). An MRI scan uses a powerful magnetic field and radio waves to produce detailed images of the brain and blood vessels. MRI scans help doctors diagnose tumors, strokes, bleeding in the brain, infections, and other brain and nervous system (neurological) conditions.
• Computerized tomography (CT) scan. A CT scan uses a series of X-rays to create detailed cross-sectional images of the brain. This helps doctors diagnose tumors, infections, brain damage, bleeding in the brain and other possible medical problems that may be causing headaches.

Treatment

Migraine treatment is aimed at stopping symptoms and preventing future attacks.

Many medications have been designed to treat migraines. Medications used to combat migraines fall into two broad categories:

• Pain-relieving medications. Also known as acute or abortive treatment, these types of drugs are taken during migraine attacks and are designed to stop symptoms.
• Preventive medications. These types of drugs are taken regularly, often daily, to reduce the severity or frequency of migraines.

Your treatment choices depend on the frequency and severity of your headaches, whether you have nausea and vomiting with your headaches, how disabling your headaches are, and other medical conditions you have.

Medications for relief

Medications used to relieve migraine pain work best when taken at the first sign of an oncoming migraine — as soon as signs and symptoms of a migraine begin. Medications that can be used to treat it include:

• Pain relievers. These over-the-counter or prescription pain relievers include aspirin or ibuprofen (Advil, Motrin IB, others). When taken too long, these might cause medication-overuse headaches, and possibly ulcers and bleeding in the gastrointestinal tract.

  Migraine relief medications that combine caffeine, aspirin and acetaminophen (Excedrin Migraine) may be helpful, but usually only against mild migraine pain.

• Triptans. Prescription drugs such as sumatriptan (Imitrex, Tosymra) and rizatriptan (Maxalt, Maxalt-MLT) are used to treat migraine because they block pain pathways in the brain. Taken as pills, shots or nasal sprays, they can relieve many symptoms of migraine. They might not be safe for those at risk of a stroke or heart attack.

• Dihydroergotamine (D.H.E. 45, Migranal). Available as a nasal spray or injection, this drug is most effective when taken shortly after the start of migraine symptoms for migraines that tend to last longer than 24 hours. Side effects can include worsening of migraine-related vomiting and nausea.

  People with coronary artery disease, high blood pressure, or kidney or liver disease should avoid dihydroergotamine.

• Lasmiditan (Reyvow). This newer oral tablet is approved for the treatment of migraine with or without aura. In drug trials, lasmiditan significantly improved headache pain. Lasmiditan can have a sedative effect and cause dizziness, so people taking it are advised not to drive or operate machinery for at least eight hours.
• Ubrogepant (Ubrelvy). This oral calcitonin gene-related peptide receptor antagonist is approved for the treatment of acute migraine with or without aura in adults. It's the first drug of this type approved for migraine treatment. In drug trials, ubrogepant was more effective than placebo in relieving pain and other migraine symptoms such as nausea and sensitivity to light and sound two hours after taking it. Common side effects include dry mouth, nausea and excessive sleepiness. Ubrogepant should not be taken with strong CYP3A4 inhibitor drugs.
• CGRP antagonists. Ubrogepant (Ubrelvy) and rimegepant (Nurtec ODT) are oral CGRP antagonists recently approved for the treatment of acute migraine with or without aura in adults. In drug trials, drugs from this class were more effective than placebo in relieving pain and other migraine symptoms such as nausea and sensitivity to light and sound two hours after taking it. Common side effects include dry mouth, nausea and excessive sleepiness. Ubrogepant and rimegepant should not be taken with strong CYP3A4 inhibitor drugs.
• Opioid medications. For people who can't take other migraine medications, narcotic opioid medications might help. Because they can be highly addictive, these are usually used only if no other treatments are effective.
• Anti-nausea drugs. These can help if your migraine with aura is accompanied by nausea and vomiting. Anti-nausea drugs include chlorpromazine, metoclopramide (Reglan) or prochlorperazine (Compro). These are usually taken with pain medications.

Some of these medications are not safe to take during pregnancy. If you're pregnant or trying to get pregnant, don't use any of these medications without first talking with your doctor.

Preventive medications

Medications can help prevent frequent migraines. Your doctor might recommend preventive medications if you have frequent, long-lasting or severe headaches that don't respond well to treatment.

Preventive medication is aimed at reducing how often you get a migraine, how severe the attacks are and how long they last. Options include:

• Blood pressure-lowering medications. These include beta blockers such as propranolol (Inderal, InnoPran XL, others) and metoprolol tartrate (Lopressor). Calcium channel blockers such as verapamil (Verelan) can be helpful in preventing migraines with aura.
• Antidepressants. A tricyclic antidepressant (amitriptyline) can prevent migraines. Because of the side effects of amitriptyline, such as sleepiness, other antidepressants might be prescribed instead.
• Anti-seizure drugs. Valproate and topiramate (Topamax, Qudexy XR, others) might help if you have less frequent migraines, but can cause side effects such as dizziness, weight changes, nausea and more. These medications are not recommended for pregnant women or women trying to get pregnant.
• Botox injections. Injections of onabotulinumtoxinA (Botox) about every 12 weeks help prevent migraines in some adults.
• CGRP monoclonal antibodies. Erenumab-aooe (Aimovig), fremanezumab-vfrm (Ajovy), galcanezumab-gnlm (Emgality), and eptinezumab-jjmr (Vyepti) are newer drugs approved by the Food and Drug Administration to treat migraines. They're given monthly or quarterly by injection. The most common side effect is a reaction at the injection site.

Ask your doctor if these medications are right for you. Some of these medications are not safe to take during pregnancy. If you're pregnant or trying to get pregnant, don't use any of these medications without first talking with your doctor.
