While there has been strong evidence for the ability of neuropsychological performance at resolution of posttraumatic amnesia to predict later productivity, there has been less conclusive evidence for the relationship of neuropsychological test scores to concurrent productivity status. The purpose of the current study was to evaluate the relationship of neuropsychological test performance at 1 year post-injury to productivity assessed at the same time point. Participants were 518 persons with medically documented TBI who were enrolled in the TBI Model Systems Research and Demonstration Project. Stepwise logistic regression was utilized to determine the contributions of neuropsychological test scores to productivity after accounting for demographic characteristics, injury severity, and pre-injury productivity. Missing neuropsychological test scores were accounted for in the model. Variables that remained in the model and accounted for a significant proportion of the variance included age, duration of impaired consciousness, pre-injury productivity, and scores on measures of GOAT, Logical Memory II, and Trail Making Test, part B. The results indicate that neuropsychological test performance provides important information regarding the ability of persons with injury to return to productive activities. The results also indicate that inability to complete neuropsychological tests at 1 year post-injury is associated with non-productive activity. [ABSTRACT FROM AUTHOR]

To investigate the frequency and risk factors of major depressive disorder(MDD) after mild to moderate traumatic brain injury (TBI), 69 TBI and 52 generaltrauma (GT) patients were prospectively recruited and studied at 3-monthspostinjury. There was a nonsignificant difference in the proportion of MDDpatients in the TBI and GT groups. Therefore, a composite MDD group (TBI andGT patients) was compared to patients who were nondepressed. Female genderwas related to MDD, but no other risk factors were identified. MDD was associatedwith disability (Glasgow Outcome Scale, Community Integration Questionnaire)and cognitive impairment. MDD was comorbid with posttraumatic stress disorder.Implications for postacute management of mild to moderate TBI are discussed. [ABSTRACT FROM AUTHOR]

Previous studies of postconcussional disorder (PCD) have utilized a dimensionalapproach (i.e., number and/or severity ratings of symptoms) to study postconcussionalsymptoms. This study used a syndromal approach (modified form of the DSM-IVcriteria) for investigating risk factors for developing PCD, 3-months postinjury.The head trauma requirement was waived in order to determine specificity ofsymptoms to traumatic brain injury. Preliminary results from this ongoingstudy indicated significant risk factors including female gender, poor socialsupport, and elevated self-reported depressive symptoms at 1-month postinjury.Comorbidities included concurrent diagnosis of major depressive disorder and/orposttraumatic stress disorder. Hispanics were significantly less likely todevelop PCD than other racial/ethnic groups. PCD resulted more frequentlyfrom motor vehicle accidents and assaults. Screening tests for PCD risk factors/comorbiditiesperformed shortly after injury (i.e., during routine follow-up clinic appointments)coupled with appropriate referrals for psychoeducational interventions andsupport groups may avoid prolonged loss of productivity and poor perceivedquality of life in these patients.
