Silent Migraine

CLICK TO RATE 

Although silent migraine is not recognized as a type of migraine by the International Headache Society, many patients are often told they are suffering from silent, or acephalgic, migraine. The terms silent migraine and acephalgic migraine are actually referring to an individual phase of a migraine attack.

Silent migraine is not a separate type of migraine. The terms “silent” and “acephalgic” are descriptive terms, not diagnostic, used to describe a migraine attack without the headache phase of the attack – a migraine with no headache.

What are silent migraines?

The typical phases of a migraine attack may include:

  1. Prodrome
  2. Aura
  3. Headache
  4. Postdrome

People typically associate migraines with the third phase of head pain. However, some migraine sufferers experience a type of migraine that has many migraine symptoms, yet the head pain is absent. The terms silent migraine and acephalgic migraine refer to a migraine attack which skips the third phase of headache.

Migraine sufferers may experience only silent migraine attacks, while others may have some migraine attacks with head pain and others without. Although silent migraines may occur at any age and in those who never experienced migraines before, most often silent migraines pop up in people who suffered from migraines with aura when they were younger.

Because many of the symptoms of silent migraines are the same as the symptoms for stroke or a transient ischemic attack (TIA), sometimes called a mini-stroke, it is very important to see a medical professional immediately to diagnose the cause of the symptoms. Ruling out stroke and other more serious disorders is crucial since the typical migraine head pain is not present.

How to get rid of silent migraines

Your doctor will recommend appropriate treatment based on the type of migraine and symptoms you experience. If you frequently experience migraine without headache, migraine treatments still may help relieve other symptoms of your migraine attacks.
