Basilar artery migraine

Basilar artery migraine: Introduction

A basilar artery migraine is a rare type of migraine, a headache that is severe, persistent and often occurs in conjunction with a wide variety of symptoms. A basilar artery migraine can be so severe that is disabling in many cases, leading to serious disruption of work, school, relationships, and social activities.

The exact cause of basilar artery migraines is uncertain, but they may be the result of a disturbance of brain chemicals and/or an abnormal functioning of the basilar artery, a major artery in the back of the brain. A classic characteristic of a basilar artery migraine is a dramatic aura, which is often a precursor to the headache. Symptoms of basilar artery migraine include neurological and sensory disturbances and a severe headache. For more information on symptoms and complications, refer to symptoms of basilar artery migraine.

Basilar artery migraine is also known as basilar-type migraine and Bickerstaff syndrome. Basilar artery migraines are rare. They can affect anyone, but are most common in young adult women.

Basilar artery migraines are often, but not always, triggered by one or more specific substances or situations. Triggers vary greatly between different people and what may trigger a basilar artery headache in one person may not in another person. Common triggers include caffeine, alcohol, dairy foods, chocolate, tomatoes, oranges, rye, wheat, and nitrates and nitrites found in certain foods, such as sausages and cold cuts. Other common triggers include hunger, overexertion, bright lights, fluorescent lights, high altitudes, and changes in weather. In some women hormonal changes due to the menstrual cycle can trigger basilar artery migraines.

Making a diagnosis of basilar artery migraine includes performing a complete evaluation that includes a medical history, including symptoms, and a physical examination. This includes a neurological examination. A neurological exam evaluates the brain and nerves and such functions as level of consciousness, reflexes, sensation, movement, balance, coordination, vision, and hearing. A referral to a neurologist, a specialist in treating neurological conditions, is generally made for definitive diagnosis and treatment of basilar artery migraine.

Because many people with basilar artery migraines have visual disturbances, including temporary blindness, an eye examination is performed to rule-out such eye conditions as detached retina. An eye examination includes testing visual acuity or sharpness of vision, checking the sharpness of peripheral vision, and testing the pressure inside the eye. The outer eye is examined using an instrument called a slit lamp, and the inner eye is examined using an instrument called an ophthalmoscope. During the exam with an ophthalmoscope, the pupils of the eye may be dilated (opened up) with a drop of medication to better visualize any changes in the retina.

The diagnostic process also involves keeping a basilar artery migraine log or diary to record the timing, symptoms, and the types of situations that occurred or substances that were ingested before the basilar artery migraine occurred. This can help to diagnose triggers and assist in making lifestyle changes that can minimize basilar artery migraine headaches. The type of treatment and its results are also recorded to help pinpoint the most effective treatment for an individual.

A diagnosis is made based on a history of at least two episodes of symptoms typical of basilar artery migraine and after ruling out other, potentially life-threatening, diseases and conditions with symptoms that mimic basilar artery migraine. These include stroke, and meningitis. This diagnostic process generally requires imaging tests, such as MRI and CT scan and possibly a lumbar puncture. It is possible that a diagnosis of basilar artery migraine can be missed or delayed because it is rare and because symptoms can be similar to symptoms of other conditions and diseases. For more information on diseases and conditions that can mimic basilar artery migraine, refer to misdiagnosis of basilar artery migraine.

In many cases, patient compliance with a good treatment plan can control symptoms of basilar artery migraine to a degree that allows a person to live a normal active life. Treatment plans include medications and avoiding substances and situations that can trigger a basilar artery migraine. For more information on treatment, refer to treatment of basilar artery migraine. ...more »
