ABSTRACTIntroduction: Mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) are highly prevalent comorbid conditions in military Veterans. However, lack of appropriate comparison groups has clouded interpretation of the chronic effects of these conditions. The present study evaluated the neuropsychological, psychiatric/neurobehavioral, and functional outcomes associated with mTBI and PTSD in a well-characterized sample of combat-exposed Veterans.Method: Participants include...

Abstract Introduction We examined reasons for low mild cognitive impairment (MCI)-to-cognitively normal (CN) reversion rates in the Alzheimer's Disease Neuroimaging Initiative (ADNI). Methods CN and MCI participants were identified as remaining stable, progressing, or reverting at 1-year of follow-up (Year 1). Application of ADNI's MCI criteria at Year 1 in addition to Alzheimer's disease biomarkers by group were examined. Results The MCI-to-CN reversion rate was 3.0%. When specific components w...

Objective: Biomarkers predict risk for Alzheimer9s disease, but the ability to predict when most people are still biomarker negative would foster earlier identification of risk. We hypothesized that memory testing - particularly combining multiple memory measures - in cognitively normal middle-aged adults would provide good prediction of 6-year progression to mild cognitive impairment (MCI). Our use of multiple measures contrasts with frequent efforts to identify the single best measure for pred...

Objective To better concurrently address emotional and neuropsychological symptoms common in veterans with comorbid post-traumatic stress disorder (PTSD) and history of traumatic brain injury (TBI), we integrated components of compensatory cognitive training from the Cognitive Symptom Management and Rehabilitation Therapy (CogSMART) programme into cognitive processing therapy (CPT) for PTSD to create a hybrid treatment, SMART-CPT (CogSMART+CPT). This study compared the efficacy of standard CPT w...

AbstractObjective: The purpose of this review was to examine sex differences in concussion, or mild traumatic brain injury (mTBI) outcome, updating previous critical reviews of the literature.Method: Within adult human studies, we reviewed a wide range of concussion outcome variables: prevalence of concussion, injury characteristics, postconcussion symptom trajectories and psychiatric distress, neuropsychological performance, and neuroimaging findings. Sports-related concussion, civilian, and mi...

Abstract We retrospectively investigated archival clinical data, including correlates of lifetime homelessness, in 503 Veterans with a history of traumatic brain injuries (86.5% mild) who completed neuropsychological evaluations and passed performance validity tests. The 471 never-homeless and 32 ever-homeless Veterans were compared on demographic factors, TBI severity, psychiatric diagnosis, subjective symptoms, and neuropsychological functioning. Homelessness history was significantly associat...
