This is a report of a study of 92 cases in which a diagnosis of migraine was made in the Section of Pediatrics at the Mayo Clinic during the six-year period of Jan. 1, 1950, through Dec. 31, 1955.

Followup letters in the form of a questionnaire were mailed to the parents of 89 patients. The results and tabulation of this information will be presented.
