Extending the categorization to include a “probable” state
migraine
MIGRAINE, TENSION-TYPE HEADACHE, TENSION-TYPE HEADACHES
The ICHD classification allows to define also probable migraine and probable tension-type headaches in those children fulfilling only 3 of the 4 criteria. Following this idea, we extended our classification system accordingly. “Probable migraine” was considered if 2 out of 3 criteria B-D were fulfilled, and “probable tension-type headache” was considered if 1 out of 2 criteria C + D was fulfilled.
