A proxy GWAS based on survey-reported parental dementia (n=6,641 proxy cases, 45,970 contro...

Mild traumatic brain injury (mTBI) is among the most common injuries sustained by post-9/11 veterans; however, these injuries often occur within the context of psychological trauma. Blast exposure, even in the absence of a diagnosable TBI, leads to changes in neural connectivity and congitive functioning. Therefore, considering clinical comorbiditi...

Cross‐sectional work suggests that deployment‐related posttraumatic sequelae are associated with increased disability in U.S. veterans deployed following the September 11, 2001 (9/11), terrorist attacks. However, few studies have examined the psychiatric and somatic variables associated with changes in functional disability over time. A total of 23...

Intimate partner violence (IPV) is prevalent among Veterans. Injuries to head, neck, and face are frequent and elevate risk for traumatic brain injury (TBI). IPV also increases risk for mental health morbidity. A better understanding of IPV’s impact on health and functioning is needed among Veterans to inform assessment and intervention. This study...

Maladaptive anger and aggression are common in United States military veterans and increases risk for impaired social relationships and functioning, justice‐involvement, and violence. Early life (before age 18) adversity predisposes veterans to later life psychopathology, though the link to increased later life anger is unclear. We analyzed cross‐s...

The Clinician-Administered PTSD Scale (CAPS) is used to measure posttraumatic stress symptoms (PTSS) and diagnose posttraumatic stress disorder (PTSD). However, its use, particularly in settings involving longitudinal assessment, has been complicated by changes in the diagnostic criteria between the fourth and fifth editions of the Diagnostic and S...

The number of women in the United States that experience blows to the head during assaults by intimate partners is substantial. The number of head blows that result in a traumatic brain injury (TBI) is virtually unknown, but estimates far exceed numbers of TBI in parallel populations (e.g., blast exposure, accidents, sports) combined. Research on t...

Elevated serum C-reactive protein (CRP) and possessing an APOE ε4 allele are two of the most prominent risk factors for cognitive and neurological dysfunction in older adults, but little is known about the unique or cumulative effects of these risk factors in young-to-middle aged adults. To further characterize these potential relationships, measur...

Objectives Recent studies suggest that close-range blast exposure (CBE), regardless of acute concussive symptoms, may have negative long-term effects on brain health and cognition; however, these effects are highly variable across individuals. One potential genetic risk factor that may impact recovery and explain the heterogeneity of blast injury’s...

Metabolic syndrome (MetS) is a cluster of vascular risk factors that can impact cognition.
