0639 Delayed Presentation of Sleep Disruption and Depressive Symptoms in Males Post Mild Traumatic Brain Injury (mTBI)

Abstract Introduction The relationship between sleep disruption and depressive symptoms is well established. Mild traumatic brain injury (mTBI) commonly associated with emotional dysregulation decreased quality. Less known about the course of mTBI its association mood over time. We hypothesized that those in acute stages (2W; 1M) would significantly differ quality compared healthy controls. As there are often sex differences depression, we focused here exclusively on males mTBI. Methods This study included 56 males, split into six groups. sample 15 (Mage=23.67, SD=5.066) 41 (Mage=26.88, SD=8.509) mTBI, at differing post-injury: 2 weeks 1, 3, 6, 12 months. Participants completed Pittsburgh Sleep Quality Index (PSQI) Beck Depression (BDI-II) to assess disturbance mood, respectively. Higher scores both measures indicate a more severe presentation disruptive symptoms. conducted one-way ANOVA examine how mean score for varied each time point. Results Compared controls was no significant variance average depression 2W, 1M, 6M, 12M (p>.05). However, 3M post-mTBI reported higher than M =9.8, SD=9.48, p=.035. greater when =7.30, SD=3.16, p=.035 M=7.0, SD=3.39, p=.037, but not other points. Conclusion Contrary our hypotheses, found did vary from either measure These results may initially present post-mTBI, which could result an inaccurate assessment severity improper treatment plan moving forward recovery. Further research larger size be useful establishing suffering experience most roughly after injury. Future work will need whether these same trends among females. Support (if any) W81XWH-12-1-0386
