Reported associations with migraine headaches. Data from the 166 survey respondents meeting diagnostic criteria for HHT and migraines. The mean score, and standard error of the mean, are illustrated, noting individual responses ranged from never (0) to always (5). As reported elsewhere,5 almost half (70, 43.3%) described sometimes having an HHT nosebleed at the time of a migraine, and in 14 cases (8.4%) this occurred with most if not all migraines.
