Classification of pediatric migraine: proposed revisions to the IHS criteria
1Palm Beach Headache Center, FL 33407, USA.
Insights
Modified International Headache Society criteria improve pediatric migraine diagnosis. These revised guidelines enhance sensitivity for identifying migraine in children and adolescents, aiding future research.
Area of Science:
- Neurology
- Pediatrics
- Headache Medicine
Background:
- The International Headache Society (IHS) classification requires adaptation for accurate pediatric migraine diagnosis.
- Children and adolescents exhibit unique migraine characteristics affecting duration, location, intensity, and associated symptoms like photophobia and phonophobia.
Purpose of the Study:
- To propose and evaluate specific, more sensitive diagnostic criteria for pediatric migraine with and without aura based on IHS modifications.
- To compare the diagnostic sensitivity of the proposed revised IHS classification against existing IHS and Vahlquist criteria in a pediatric cohort.
Main Methods:
- Retrospective evaluation of 45 children and adolescents diagnosed at a headache center.
- Comparison of diagnostic rates for migraine using the standard IHS classification, Vahlquist criteria, and the proposed revised IHS (IHS-R) classification by a single pediatric neurologist.
Main Results:
- The proposed IHS-R classification demonstrated higher diagnostic sensitivity for migraine (80%) compared to IHS (53%) and Vahlquist (69%) in the total sample.
- In patients under 12 years old (n=22), IHS-R (73%) also showed greater sensitivity than IHS (50%) and Vahlquist (68%).
Conclusions:
- The proposed revisions to the IHS classification significantly enhance diagnostic sensitivity for pediatric migraine.
- These modified criteria offer a foundation for future research and improved diagnostic guidelines for pediatric migraine within the IHS framework.
Abstract:
The International Headache Society classification lends itself to modification to significantly improve the diagnostic sensitivity of migraine in the pediatric population. Children and adolescents require special modifications relating to duration, location, quality of intensity, and symptoms related to photophobia and phonophobia. We propose specific criteria for pediatric migraine with and without aura which are more sensitive. Forty-five children and adolescents seen at a headache center were evaluated, retrospectively, comparing diagnostic criteria of the International Headache Society, Vahlquist, and the proposed revised IHS classification for clinical diagnosis by a single examiner (pediatric neurologist)--comparing diagnostic rates for migraine of the total sample: IHS (53%), Vahlquist (69%), and IHS-R (80%) and evaluating a subset of those patients less than 12 years (n = 22): IHS (50%), Vahlquist (68%), and IHS-R (73%). The proposed revisions to IHS for pediatric migraine were more sensitive than existing criteria. These revisions may help to form the basis for future research guidelines and for further modifications to improve the diagnostic sensitivity of pediatric migraine using the IHS model.
