This preliminary study aimed to determine if adding mirtazapine to risperidone might improve negative and cognitive symptoms in schizophrenia. In an 8-week, double-blind clinical trial, we randomly assigned 21 stabilized outpatients with schizophrenia undergoing risperidone treatment to adjunctive treatment with either mirtazapine or a placebo. The(More)
BACKGROUND The catechol-O-methyltransferase (COMT) gene val158met polymorphism (rs4680) has been found to be associated with various psychiatric phenotypes including panic disorder. Considering the probable genetic influence of COMT on the pathogenesis of panic disorder and white matter connectivity, the present study investigated white matter connectivity(More)
BACKGROUND Strong lifetime and current comorbidity occur between panic disorder and depression. However, no study has examined the influence of comorbid depression on brain structural characteristics in panic disorder patients. We aimed to compare gray matter (GM) volume and white matter (WM) connectivity in panic disorder patients with and without(More)
PURPOSE Although the effectiveness of Mindfulness-Based Cognitive Therapy (MBCT) for panic disorder (PD) has been studied previously, data on the predictors of treatment outcomes in MBCT for PD are scarce. MATERIALS AND METHODS Eighty patients with PD were screened to analyze treatment outcomes such as MBCT completion, treatment response, and remission(More)
The frontal cortex might play an important role in the fear network, and white matter (WM) integrity could be related to the pathophysiology of panic disorder (PD). A few studies have investigated alterations of WM integrity in PD. The aim of this study was to determine frontal WM integrity differences between patients with PD without comorbid conditions(More)
BACKGROUND Panic disorder (PD) is associated with an increased risk of suicide attempt (SA). However, no study has examined the neural correlates of SA in PD. The goal of this study was to evaluate alterations in white matter (WM) and gray matter (GM) in patients with PD with and without a history of SA. METHODS Twelve patients with PD and a history of SA(More)
BACKGROUND The polymorphisms of serotonergic genes (5-HTTLPR and HTR1A rs6295) and separation life events have been studied to find an association with panic disorder, respectively. However, there are no studies that have yet evaluated the interaction effect between serotonergic genes and separation life events for panic disorder. METHODS For this study,(More)
PURPOSE Oseltamivir is widely used in the treatment and prophylaxis of influenza A and B viral infections. It is ingested as an oral prodrug that is rapidly metabolized by carboxylesterase 1 (CES1) to its active form, oseltamivir carboxylate. Dexamethasone is also used in the treatment of acute respiratory distress syndrome, a severe complication of(More)
The risk of suicide is disproportionately high among people diagnosed with schizophrenia or schizophreniform disorder. Brain imaging studies have shown a few relationships between neuroanatomy and suicide. This study examines the relationship between alterations in brain white matter (WM) and suicidal behavior in people with schizophrenia or(More)
OBJECTIVE Intolerance of uncertainty (IU) is a transdiagnostic construct in various anxiety and depressive disorders. However, the relationship between IU and panic symptom severity is not yet fully understood. We examined the relationship between IU, panic, and depressive symptoms during mindfulness-based cognitive therapy (MBCT) in patients with panic(More)
