SLEEP DISTURBANCE IN CHILDREN WITH MIGRAINE

Objectives: To determine if (a) children with migraine experience greater sleep disturbances than their siblings, (b) those with more severe migraine have greater levels of sleep disruption, and (c) these sleep disturbances lead to greater behavioral problems and more missed school.

Methods: Cases aged 6–18 years with a diagnosis of migraine for >6 months, who had at least one sibling without migraine in the same age range were identified through the neurology clinic database or at time of clinic visit. Parents completed the (1) demographic, general health, and migraine information questionnaire, (2) Child Sleep Habits Questionnaire, and (3) BASC 2 Parent Rating Scales for each child.

Results: Cases with migraine had higher Total Sleep (p<0.02), Sleep Delay (p<0.03) and Daytime Sleepiness scores (p<0.001) than controls. Cases with more severe migraines had higher Total Sleep (p<0.01) and Sleep Duration scores (p<0.03) than those with milder headaches. In cases, higher Total Sleep scores predicted greater behavior problems on all 4 composite scales on the BASC 2 (Externalizing Behavior p<0.05, Internalizing Behavior p<0.005, Behavior Systems Index p<0.003 and Adaptability Skills p<0.006).

Conclusion: Children with migraine are prone to greater sleep and behavioral disturbances than children without headache. Sleep disorders should be routinely queried and appropriate advice on sleep hygiene provided.
