Zusammenfassung:Having a preexisting migraine disorder might be a risk factor for a prolonged recovery following a sport-related concussion. We examined whether having a migraine history was associated with a prolonged return to academics and athletics following a concussion. High school and collegiate athletes (n = 1265; 42% female) who sustained a sport-related concussion were monitored by athletic trainers using a web-based surveillance system that collects information about concussion recovery. Nonparametric Kolmogorov-Smirnov tests (KS) were used to compare days to return to academics/athletics across groups due to non-normally distributed outcome variables and unequal distributions of scores between groups. Chi-squared tests were used to examine the proportion of players who had not returned to academics/athletics at 7, 14, and 21 days post-injury stratified by self-reported migraine history. There were 117 athletes (9.2%) who reported a preinjury migraine history. Athletes with a history of migraine took a median of 6 days to return to academics (mean [M] = 10.6, standard deviation [SD] = 14.2) and 15.5 days to return to athletics (M = 23.8, SD = 30.8), while those with no migraine history took a median of 5 days to return to academics (M = 7.5, SD = 10.9) and 14 days to return to athletics (M = 19.4, SD = 19.4). There were no statistically significant differences in days to return to school or athletics between the groups (KS p > 0.05). However, a lower percentage of athletes with a history of migraine had returned to school after 7 days (57% vs. 68%, χ  = 5.53, p = 0.02), 14 days (75% vs. 88%, χ  = 14.21, p
