BACKGROUND Psychotic disorders are characterized by aberrant neural connectivity. Alterations in gyrification, the pattern and degree of cortical folding, may be related to the early development of connectivity. Past gyrification studies have relatively small sample sizes, yield mixed results for schizophrenia, and are scant for psychotic bipolar and(More)
BACKGROUND Schizophrenia, schizoaffective disorder, and psychotic bipolar disorder overlap with regard to symptoms, structural and functional brain abnormalities, and genetic risk factors. Neurobiological pathways connecting genes to clinical phenotypes across the spectrum from schizophrenia to psychotic bipolar disorder remain largely unknown. METHODS We(More)
Patients with psychotic disorders appear to exhibit greater impulsivity-related behaviors relative to healthy controls. However, the neural underpinning of this impulsivity remains uncertain. Furthermore, it remains unclear how impulsivity might differ or be conserved between psychotic disorder diagnoses in mechanism and manifestation. In this study,(More)
Relative to healthy controls, lithium free bipolar patients exhibit significant gray matter abnormalities. Lithium, the long-time reference standard medication treatment for bipolar disorder, has been proposed to be neuro-protective against these abnormalities. However, its effects on cortical thickness and hippocampal subfield (HSF) volumes remain(More)
BACKGROUND An elevated prevalence of Type 2 diabetes (T2D) has been observed in people with psychotic disorders and their relatives compared to the general population. It is not known whether this population also has increased genetic risk for T2D. METHODS Subjects included probands with schizophrenia, schizoaffective disorder, or psychotic bipolar I(More)
INTRODUCTION Whereas most patients with obsessive-compulsive disorder (OCD) are well controlled with pharmacological and cognitive behavioral therapy, 10% to 20% remain severe and refractory. Stereotactic lesions in the anterior limb of the internal capsule (ALIC) have been used for decades to treat these patients. Recent studies using stereotactic(More)
OBJECTIVE To determine whether children in rural areas have worse health than children in urban areas after liver transplantation (LT). STUDY DESIGN We used urban influence codes published by the US Department of Agriculture to categorize 3307 pediatric patients undergoing LT in the United Network of Organ Sharing database between 2004 and 2009 as urban(More)
