BACKGROUND The mechanisms that contribute to emotion dysregulation in anxiety disorders are not well understood. Two common disorders, generalized anxiety disorder (GAD) and panic disorder (PD), were examined to test the hypothesis that both disorders are characterized by hypo-activation in prefrontal cortex (PFC) during emotion regulation. A competing(More)
BACKGROUND Anxiety disorders and insomnia are each prevalent, impairing, and highly comorbid. However, little is known about whether specific types of sleep complaints are associated with specific anxiety disorders, and whether poor sleep has an additive effect on functional impairment in anxiety disorders. METHOD Data from the German Health Survey (GHS;(More)
The possibility of individualized treatment prediction has profound implications for the development of personalized interventions for patients with anxiety disorders. Here we utilize random forest classification and pre-treatment functional magnetic resonance imaging (fMRI) data from individuals with generalized anxiety disorder (GAD) and panic disorder(More)
BACKGROUND Although evidence exists for abnormal brain function across various anxiety disorders, direct comparison of neural function across diagnoses is needed to elicit abnormalities common across disorders and those distinct to a particular diagnosis. AIMS To delineate common and distinct abnormalities within generalised anxiety (GAD), panic and(More)
OBJECTIVE Cognitive behavioral therapy (CBT) is empirically supported for the treatment of anxiety disorders; however, not all individuals achieve recovery following CBT. Positive emotions serve a number of functions that theoretically should facilitate response to CBT - they promote flexible patterns of information processing and assimilation of new(More)
BACKGROUND Suicide rates have risen considerably in the United States Army in the past decade. Suicide risk is highest among those with past suicidality (suicidal ideation or attempts). The incidence of posttraumatic stress disorder (PTSD) and depressive illnesses has risen concurrently in the U.S. Army. We examined the relationship of PTSD and depression,(More)
BACKGROUND The neural processes underlying the benefits of cognitive behavioral treatment (CBT) for generalized anxiety disorder (GAD) are not well understood. METHODS Twenty-one (n=21) adults with a principal diagnosis of GAD and eleven (n=11) non-anxious healthy controls (HC) underwent functional magnetic resonance imaging while completing a facial(More)
PURPOSE Suicidal behaviors have increased in the US Army since 2005. To identify potential interventions for suicide risk, we examined the relationship between alcohol and energy drink use, independently and in combination, and rates of seriously considering and/or attempting suicide in US Army soldiers. METHODS This study used the DoD Survey of Health(More)
BACKGROUND Childhood emotional maltreatment (CEM) increases the likelihood of developing an anxiety disorder in adulthood, but the neural processes underlying conferment of this risk have not been established. Here, we test the potential for neuroimaging the adult brain to inform understanding of the mechanism linking CEM to adult anxiety symptoms. METHOD(More)
BACKGROUND Much about the long-term course of anxiety disorders is unknown. The present study utilizes a naturalistic, longitudinal, short-interval follow-up design to elucidate the course of anxiety disorders over 14 years in a largely middle-aged adult sample recruited from out-patient psychiatry and primary care facilities. METHOD The sample consisted(More)
