Potential factors influencing recovery from concussion in collegiate student-athletes

Background Factors including sex, previous diagnosis of migraines, previous diagnosis of Attention Deficit Disorder/Attention Deficit Hyperactivity Disorder, and a history of concussion may influence the length of recovery from concussion in collegiate student-athletes. Purpose To better understand factors that may influence recovery from concussion in collegiate-student athletes. Methods A total of 91 student-athletes from a Division I NCAA University who sustained concussions from the fall of 2011 to the spring of 2015 were evaluated. They were considered recovered from their concussion when neurocognitive and symptom scores returned to baseline and they were cleared by their physician. Analyses of variance were conducted to determine if potential factors influenced concussion recovery (p < .0125). Results No significant differences were found for sex (males = 7.4 ± 5.9; females = 8.3 ± 4.8 days; p = 0.417), previous diagnosis of migraines (diagnosis = 8.0 ± 5.7; no diagnosis = 7.8 ± 5.4 days; p = 0.926), or history of concussion (history = 8.3 ± 5.7; no history = 5.6 ± 3.4 days; p = 0.088). However, a significant difference in the length of recovery was found between those with a previous diagnosis of Attention Deficit Disorder/Attention Deficit Hyperactivity Disorder and those without (diagnosis = 13.3 ± 7.3; no diagnosis = 7.3 ± 4.9 days; p = 0.002). Conclusion Student-athletes with Attention Deficit Disorder/Attention Deficit Hyperactivity Disorder show significantly longer recovery from concussions than those without. Further investigation of this and other factors that influence recovery from concussion may help in concussion recovery and return-to-play guidelines that improve student-athlete well-being.
