About 65-80% of children with migraines interrupt their normal activities because of the symptoms. In one study of 970,000 self-reported migraineurs aged 6-18 years, 329,000 school days were lost per month. The burden of migraines may cause emotional changes such as anxiety or sadness.
Appropriate diagnosis and treatment of pediatric migraines can greatly improve the quality of a child’s life. Migraines are a clinical diagnosis. As such, specific criteria have been established to make the diagnosis. The criteria for a pediatric migraine without aura is as follows:
- At least five attacks fulfilling criteria B-D.
- Headache attack lasting 1-48 hours.
- Headache has at least two of the following: 1) Bilateral or unilateral location. 2) Pulsating quality. 3) Moderate to severe intensity. 4) Aggravation by routine physical activity.
- During the headache, at least one of the following: 1) Nausea and/or vomiting. 2) Sensitivity to light and/or sound.
- Signs which may precede the attack by hours or days include: mood changes, irritability, euphoria, increased thirst, increased urination, fluid retention, food cravings, yawning, and sighing.
