Cyclic Vomiting Syndrome and Primary Headache
Cyclic vomiting syndrome and benign paroxysmal torticollis are associated with a very high risk of developing headache, mostly migraine, later in life. This according to a longitudinal study that assessed the rate of headache in patients presenting with cyclic vomiting syndrome and benign paroxysmal torticollis during infancy and defined the main clinical features of the disorder. Researchers administered a questionnaire to the parents of pediatric patients with previous diagnosis of cyclic vomiting syndrome and/or benign paroxysmal torticollis. They found:
- 82 patients with cyclic vomiting syndrome and 33 with benign paroxysmal torticollis were included in the final analysis.
- 79% of patients with cyclic vomiting syndrome presented with headache during the follow-up with a mean age at onset of 6 years.
- 67% of patients with benign paroxysmal torticollis suffered from headache during the follow-up with a mean age at onset of 5 years.
