Diagnosis and Treatment of Migraine Headaches

By August 16, 2019Uncategorized

Last week, we talked about migraine headache symptoms and possible triggers.  This week we’ll talk about how the diagnosis is made, and what treatment options are available.

How does your doctor make the diagnosis of migraine?
The first thing your doctor will do is get a good description of your headaches.  The doctor will use the description to determine if your headaches fit the migraine diagnosis.  We talked about these qualities last week.

How are migraine headaches treated?
Several medications from different classes are available to treat migraine.  The treatment approach depends on the severity and frequency of headaches.
Treatment of the acute headache
For patients who have headache symptoms less than an average of 2 days each week, we treat with medications taken only when a headache occurs.  Here is an idea of the medications we recommend.
For mild to moderate intensity headaches – Over-the-counter (OTC) medications, including acetaminophen, ibuprofen, naproxen, or caffeine containing medications such as Excedrin Migraine.  Many migraines respond well to over the counter treatment options.
For mild to moderate intensity headaches that do not respond to OTC treatments, or for moderate to severe migraines – Prescription drugs in the triptan class, such as sumatriptan, eletriptan, rizatriptan, and others, or prescription medications in the ergotamine class, such as Migranal.
Evidence shows that acute treatment works best if taken as soon as possible after the onset of migraine, or during the aura (if you have one), before the pain progresses.  OTC drugs have been shown to have comparable effectiveness to prescription medications for most patients, if they are taken early enough.
Medications containing opiates or barbiturates should NOT be taken for acute migraine, for multiple reasons, including the increased risk of developing chronic daily headaches.
Treatment to prevent headaches
Preventive (or prophylactic) therapy is recommended for migraine patients in the following situations:
  • Headaches occurring more than 2 days a week
  • Headaches that severely limit the quality of life despite acute headache treatment
  • Inability to take acute headache treatments (due to side effects or other medical problems)
  • Presence of severe symptoms associated with headaches, such as loss of speech or stroke-like symptoms.
What are the goals of preventive therapy?
  • Reduce the frequency, severity, and duration of headaches
  • Improve responsiveness to acute treatment
  • Reduce the level of disability/improve quality of life
  • Reduce the excessive or overuse of acute medications (which can lead to rebound headaches)
  • Reduce the cost of treatment
Which preventive treatment is right for you?
There are a number of different classes of medication which can be used for prevention of headaches.  Different medications have different safety and cost factors which may play a role in deciding which medication is best for you.  Some patients respond better to certain medications than others.  It is a very individualized treatment.
Preventive medications are usually started at low doses, and gradually increased based on your response.  It may take 2-3 months for you to notice a decrease in frequency or severity of headaches, so remember to be patient and work with your doctor to get the medication and the dose that is right for you.
