MIGRAINE HEADACHE
1. What is a migraine?
A migraine is a
neurological disorder that causes recurrent attacks of moderate to severe
headache. The pain is often throbbing and may occur on one side of the head,
although both sides can be affected.
2. Common symptoms
Pain: Crescendo pattern; headache usually pulsating/throbbing, but not always; unilateral. Pain is aggravated
with routine physical activity.
Duration: 4 to 72 hours
- Patient retreats to a dark, quiet room
- Nausea, vomiting, and anorexia
- Photophobia: Sensitivity to light
- Phonophobia: Sensitivity to sound
- Osmophobia: Fear of smell/odors
Migraine with aura (Focal disturbances of
neurological function) → Visual disturbances occur commonly
and may consist of field defects (scotoma), or luminous visual hallucinations
such as stars, sparks, unformed light flashes (photopsia), geometric patterns,
or zigzags of light, or of some combination of field defects and luminous
hallucinations (scintillating scotomas). Other focal disturbances such as
aphasia or numbness, paresthesia, clumsiness, dysarthria, disequilibrium, or
weakness in a circumscribed distribution may also occur.
Potential triggers:
Emotional or physical stress, Lack or excess of sleep, bright light, loud
noises, Variations in caffeine intake, alcoholic beverages, chocolate, cheese,
nitrates, tyramines, Hormonal changes, menstruation, or use of OCPs

Recommendations for use of prophylactic migraine medication
Start with a low dose and titrate slowly
Decrease in headache frequency may be
imperceptible the 1st month:
» For the first month, a 10% decrease in
frequency is considered successful
» Improvement is cumulative, may take 6
months to reach efficacy
» Success = 50% reduction in frequency
After a 6-month period of headache stability,
periodically evaluate.
