Clinical Information
  • A class of disabling primary headache disorders, characterized by recurrent unilateral pulsatile headaches. The two major subtypes are common migraine (without aura) and classic migraine (with aura or neurological symptoms). (international classification of headache disorders, 2nd ed. Cephalalgia 2004: suppl 1)
  • A common, severe type of vascular headache often associated with increased sympathetic activity, resulting in nausea, vomiting, and light sensitivity
  • A subtype of migraine disorder, characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred vision; hallucinations; vertigo; numbness; and difficulty in concentrating and speaking. Aura is usually followed by features of the common migraine, such as photophobia; phonophobia; and nausea. (international classification of headache disorders, 2nd ed. Cephalalgia 2004: suppl 1)
  • If you suffer from migraine headaches, you're not alone. About 12 percent of the United States Population gets them. Migraines are recurring attacks of moderate to severe pain. The pain is throbbing or pulsing, and is often on one side of the head. During migraines, people are very sensitive to light and sound. They may also become nauseated and vomit. Migraine is three times more common in women than in men. Some people can tell when they are about to have a migraine because they see flashing lights or zigzag lines or they temporarily lose their vision. Many things can trigger a migraine. These include
    • anxiety
    • stress
    • lack of food or sleep
    • exposure to light
    • hormonal changes (in women)
    doctors used to believe migraines were linked to the opening and narrowing of blood vessels in the head. Now they believe the cause is related to genes that control the activity of some brain cells. Medicines can help prevent migraine attacks or help relieve symptoms of attacks when they happen. For many people, treatments to relieve stress can also help
  • Neural condition characterized by a severe recurrent vascular headache, usually on one side of the head, often accompanied by nausea, vomiting, and photophobia, sometimes preceded by sensory disturbances; triggers include allergic reactions, excess carbohydrates or iodine in the diet, alcohol, bright lights or loud noises
