OBJECTIVE Delirium is a common and potentially life-threatening clinical syndrome. The authors investigated resting-state functional connectivity in patients with delirium to elucidate possible neural mechanisms underlying this disorder. METHOD Twenty-two patients underwent initial functional MRI at rest during an episode of delirium. Of these patients,(More)
Although social skills training (SST) is an effective approach for improving social skills for schizophrenia, the motivational deficit attenuates its efficacy. Virtual reality (VR) applications have allowed individuals with mental disabilities to enhance their motivation for rehabilitation. We compared SST using VR role-playing (SST-VR) to SST using(More)
OBJECTIVES Anhedonia in schizophrenia results from a deficit in anticipatory pleasure rather than consummatory pleasure. This study aimed to determine the neural basis of the predictive and experiential components of anticipatory pleasure in schizophrenia. METHODS A hedonic rating task was performed by 15 patients with schizophrenia and 17 controls while(More)
BACKGROUND Most previous studies on the efficacy of antipsychotic medication for the treatment of delirium have reported that there is no significant difference between typical and atypical antipsychotic medications. It is known, however, that older age might be a predictor of poor response to antipsychotics in the treatment of delirium. The objective of(More)
We sought to compare the angiographic findings and mortality in patients with non-ST-segment elevation (NSTEMI) versus ST-segment elevation myocardial infarction (STEMI) undergoing early invasive intervention. Of 11,872 patients enrolled in the Korean Acute Myocardial Infarction Registry from November 2005 to January 2008, we studied patients with NSTEMI(More)
Having a relationship with one’s parents is a fundamental social interaction and is a significant environmental factor in the long-term course of illness in schizophrenia. We explored subjective reports regarding the communicative relationship with parents and the implicit behavioral and neural responses of patients toward stimuli that referred to parents.(More)
Impaired social functioning has been reported in patients with schizophrenia. This study aimed to examine characteristics of interpersonal behaviors in patients with schizophrenia during various social interactions using the virtual reality system. Twenty-six patients and 26 controls engaged in the virtual conversation tasks, including 3 positive and 3(More)
IMPORTANCE Exploration of the ability to process socially relevant events portrayed by biological motion and to identify underlying neuronal processes can provide clues for understanding the pathophysiology of psychosis. Individuals with schizotypal personality disorder (SPD) have pervasive interpersonal deficits and odd behaviors. An understanding of the(More)
AIM Recently, cognitive therapy in people at ultra-high risk (UHR) for psychosis has been reported to show modest treatment benefits. The aim of this study was to assess the feasibility and efficacy of cognitive therapy in reducing psychiatric symptoms in UHR people in Korea. METHODS We developed cognitive therapy for people at UHR for psychosis inspired(More)
INTRODUCTION The purpose of this research is to evaluate the prospects for the use of 4-(trans-18F-fluoranylmethyl)-N-[2-[4-(2-methoxyphenyl)piperazin-1-yl]ethyl]-N-pyridin-2-ylcyclohexane-1-carboxamide (18F-Mefway) in comparison to 18F-trans-4-fluoro-N-2-[4-(2-methoxyphenyl)piperazin-1-yl]ethyl]-N-(2-pyridyl)cyclohexanecarboxamide (18F-FCWAY) for the(More)
