Comparative StudyPediatric migraine equivalents: occurrence and clinical features in practice.
Migraine equivalents of infancy, childhood, and adolescence are recognized periodic, paroxysmal syndromes without associated headache that are thought to be migrainous in etiology. Five such equivalents are presently recognized. Their clinical features and relative frequency in ambulatory pediatric neurology practice have not been well documented. ⋯ There was variation in the age of onset of a particular equivalent with considerable overlap observed. Coexisting more typical migraines were observed in from 10% (benign paroxysmal torticollis) to 70% (abdominal migraines/cyclical vomiting) of the cases. In conclusion, pediatric migraine equivalents occur with relative frequency in ambulatory practice, possessing discrete clinical features that have a clear relationship to more typical migrainous phenomena.
