Article
Background and Objectives Prescription opioid misuse is an established problem in the United States. Less information is known regarding the clinical and cognitive characteristics of prescription opioid misusers, specifically in a college age population. This study sought to characterize individuals who misuse prescription opioids and the differenc...
Article
Background: Engagement in sexual activity is common among adolescents and can be considered part of adolescent development, but it carries potential life-changing consequences. Methods: This study examined if clinical and cognitive differences existed between adolescents who engaged in voluntary sexual behavior before age 15, between ages 15 to...
Article
Excoriation (skin-picking) disorder (SPD) has similarities to obsessive-compulsive disorder (OCD) and is included within the obsessive-compulsive and related disorders (OCRD) diagnostic class in DSM-5. Separate neuroimaging and neurocognitive studies suggest that people affected by SPD find it difficult to inhibit dominant motor responses due to a...
Article
Excoriation (skin-picking) disorder (SPD) has similarities to obsessive-compulsive disorder (OCD) and is included within the obsessive-compulsive and related disorders (OCRD) category in DSM-5. Separate neuroimaging and neurocognitive studies in SPD implicate difficulty with motor response inhibition and top-down cognitive control in the disorder....
Article
Background: There is little research concerning whether race is associated with different clinical presentations of psychiatric disorders. Understanding the racial aspects of cognitive differences among depressed adults could help identify specific targets for depression treatment. Methods: We recruited 59 participants (52.5% white, 47.5% Africa...
Article
Trichotillomania is a prevalent but often hidden psychiatric condition, characterized by repetitive hair pulling. The aim of this study was to confirm or refute structural brain abnormalities in trichotillomania by pooling all available global data. De-identified MRI scans were pooled by contacting authors of previous studies. Cortical thickness an...

Gambling disorder affects approximately 1.1–3.5% of the population, with the rates being higher in young adults. Despite this high prevalence, little is known regarding which pathological gamblers decide to seek treatment. This study sought to examine the differences in three groups of pathological gamblers: those who did not seek treatment (n = 94...
Article
Excoriation (skin-picking) disorder (SPD) shares symptomology with other obsessive-compulsive and related disorders. Few studies, however, have examined the neurological profile of patients with SPD. This study examined differences in cortical thickness and basal ganglia structural volumes between 20 individuals with SPD and 16 healthy controls usi...

While it is well established that gambling disorder is associated with alcohol use disorder, less is known regarding whether sub-clinical alcohol consumption increases gambling behavior. This study examined the effects of varying levels of alcohol consumption on clinical and cognitive measures. The sample consisted of 572 non-treatment seeking gamb...

Understanding obsessive-compulsive behavior in medical students and law students is necessary for administrators and educators to properly work with students struggling with obsessionality. We aim to compare the differences in obsessive symptoms between medical students, law students and a control population. A total of 100 third-year medical stude...

Objective Outcome after aneurysmal subarachnoid hemorrhage (SAH) depends critically on delayed cerebral ischemia (DCI) – a process driven primarily by vascular events including cerebral vasospasm, microvessel thrombosis, and microvascular dysfunction. This study sought to determine the impact of postconditioning – the phenomenon whereby endogenous...
Article
INTRODUCTION: Cerebral Aneurysm rupture results in significant morbidity and mortality. TNF-a has been associated with cerebral aneurysms, but potential mechanisms have not been established, and its role in phenotypic modulation is unknown. Therapy targeting TNF-a may represent a novel treatment strategy for cerebral aneurysms. METHODS: Cultured ce...
Article
Vasospasm-induced delayed cerebral ischemia remains a major source of morbidity in patients with aneurysmal subarachnoid hemorrhage (SAH). We hypothesized that activating innate neurovascular protective mechanisms by preconditioning (PC) may represent a novel therapeutic approach against SAH-induced vasospasm and neurological deficits and, secondar...
