Abstract

Abstract: The occurrence of persistent postconcussive symptoms (PCS) associated with traumatic brain injury (TBI) is an increasing cause of disability and lost productivity. The reasons for these persistent symptoms in a percentage of even mild TBI are poorly understood. The existence of comorbid conditions such as post-traumatic stress disorder or other traumatic injuries may be factors that impact the presence of PCS. We expect that greater levels of affective symptoms will be associated with increases in PCS assessed on the Neurobehavioral Symptom Inventory (NSI). TBI subjects ( N = 69) who were seen 1 year post-injury were recruited from a larger cohort study of TBI. Subjects were administered the NSI, Brief Symptom Inventory-18 (BSI-18) and the Post Traumatic Stress Disorder Checklist (PCL). Data were analyzed using Spearman's rho correlations and analysis of variances. We found significant correlations between the four NSI factors and the three BSI factors and the PCL total score. Mild TBI subjects were found to have the highest correlations between affective and somatic symptoms. These findings support our hypothesis that affective states are associated with higher PCS reporting and that early identification and treatment may decrease PCS.
