The Contribution Of Mild Traumatic Brain Injury/Concussion To The Development Of Post-Traumatic Stress Disorder Symptoms, Kylie Lauren Marshall

Open Access Theses & Dissertations

A controversial issue is whether TBI is a necessary precursor to the development of PTSD symptoms, or if the two variables are mutually exclusive. Recent rodent-models reveal that a stressful environment cannot cause PTSD symptoms directly without TBI, yet it is unknown if PTSD symptoms can develop following a TBI. This study provides a potential analogue to study this relationship by evaluating the effects of sports-related concussion. Purpose: This study investigated two questions, 1) Is there a significant difference in the frequency of PTSD symptoms reported by athletes at baseline (BL) testing and post-concussion (PC) testing over time? 2) Is …

Predicting Protracted Recovery From Sports-Related Concussion Using Computerized Neurocognitive Test Scores And Symptom Cluster Scores, Amanda Sepulveda

Open Access Theses & Dissertations

Background: A previous study showed that symptom evaluation, in conjunction with computerized neurocognitive testing, improved predictions of protracted recovery in a group of male high school football players. The determination of prognosis following sports-related concussion can be used to facilitate return-to-play and academic decision making in concussion management.

Purpose: The purpose of this study was to replicate and extend previous research in determining the accuracy, sensitivity, specificity, and predictive value of computerized neurocognitive test scores and symptom cluster scores in predicting protracted recovery following sports-related concussion.

Study Design: Systematic replication, Cohort study (prognosis)

Methods: 30 concussed collegiate athletes were followed …
