Migraine headache in children.

INTRODUCTION

Diagnosis of migraine headache in children can be difficult as it depends on subjective symptoms; diagnostic criteria are broader than in adults. Migraine occurs in 3% to 10% of children and increases with age up to puberty. Migraine spontaneously remits after puberty in half of children, but if it begins during adolescence it may be more likely to persist throughout adulthood.

METHODS AND OUTCOMES

We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute attacks, and of prophylaxis for migraine headache in children? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

RESULTS

We found 22 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

CONCLUSIONS

In this systematic review we present information relating to the effectiveness and safety of the following interventions: for acute symptom relief (antiemetics, codeine phosphate, non-steroidal anti-inflammatory drugs [NSAIDs], paracetamol, and 5HT1 antagonists [such as triptans]) and for prophylaxis (beta-blockers, dietary manipulation, pizotifen, progressive muscle relaxation, stress management, thermal biofeedback, and topiramate).
