When to image neurologically normal children with headaches: development of a decision rule
The aim of this study was to develop and refine a decision rule on when to undertake brain imaging (BI) in neurologically normal children with headaches. Methods:
From the literature and a questionnaire study, a list of red flags (RFs) was drawn-up. During the prospective 4-year period, consecutive children with headache were classified according to RFs and the headache diagnosis. Result:
Three of 709 (0.4%) neurologically normal children had significant brain abnormalities. BI was carried out in 389 of 498 (78%) children with RFs. Significant abnormalities were found in three of 389 children (0.8%), all had unclassified headache (UH). BI was not arranged for the 211 children with no RFs. None of these developed RFs or abnormal signs on follow-up for a mean of 13 months. Conclusion:
In addition to BI for those with neurological signs, we think BI should be considered for neurologically normal patients with UH and RFs. This would have saved imaging children needlessly: only 101 of 709 (14%) would have had scans arranged, instead of 389 of 709.
