Abstract
Falling asleep as a means of ending migraine attack was studied in 133 4–16-year-old children in out-patient settings. Children registered 999 migraine attacks in headache diaries using a visual analogue scale (VAS) in 409 attacks and a five-face scale in 590 attacks. The distribution of maximal pain intensity was similar on both scales; on VAS 88% assigned grades between 63 and 100, and on the face scale 93% assigned grades of 4 or 5. Children fell asleep during 33% of the attacks ( n = 329), in 64% of these within the first hour ( n = 209). Of the children, 68% ( n = 91) had fallen asleep at least once during an attack. Falling asleep was more common in children under 8 years of age than in older children. In those under 8 years, 62% (95% confidence interval (CI) 49–75%) of attacks were resolved by sleep, in those aged 8–12 years 34% (26–41%), and in children > 12 years 24% (15–33%) (anova, P < 0.0001). Pain was relieved without sleep in 43% ( n = 431) of attacks, in 38% of these ( n = 383) within the first 4 h. The data on migraine resolution were missing for 24% ( n = 239) of the attacks, most often because the attack exceeded the 5-h observation period. This study confirms that migraine attacks in children are extremely painful and often resolve during an interval of sleep in children under 8 years of age.
