We have previously reported decreased heart rate variability upon standing in panic disorder patients compared with controls. In this study, we extend our report to include patients with major depression (n = 19). Compared to normal controls (n = 20) and panic disorder patients (n = 30), there was no significant difference in the immediate changes in heart(More)
Schizophrenic patients commonly suffer weight gain, which is often associated with widely prescribed antipsychotic medicines. It is distressing to most patients who experience it and may affect their response to treatment of schizophrenia. Weight gain is also associated with treatment noncompliance and several medical conditions. This study explored the(More)
The main objective of the present study was to determine the relationship between treatment responses of delirium and genetic polymorphisms in the dopamine transporter. The optimal dosages of haloperidol and risperidone in the treatment of delirium were also investigated. Either haloperidol or risperidone was administered to delirium patients, and delirium(More)
BACKGROUND DNA methylation in the promoter region of the glucocorticoid receptor gene (NR3C1) is closely associated with childhood adversity and suicide. However, few studies have examined NR3C1 methylation in relation to major depressive disorder (MDD) and hippocampal subfield volumes. We investigated the possible association between NR3C1 methylation and(More)
OBJECTIVE The primary aim of this study was to compare electronic monitoring with other measures of adherence to antipsychotic medication in outpatients with schizophrenia. The secondary aim of the study was to analyze the relationships between adherence and other clinical parameters. METHOD Fifty-one patients diagnosed with schizophrenia were monitored(More)
OBJECTIVES Dysfunction of the hypothalamic-pituitary-gonadal axis may contribute to the pathophysiology of schizophrenia. Recent neuroendocrinological studies have suggested that gonadal sex hormones, including androgens and estrogen, play a significant role in the pathophysiology of schizophrenia. The purpose of this study was to determine any correlation(More)
The aim of this study was to evaluate the relationship of serum reproductive hormone levels with cognitive function and negative symptoms in schizophrenic women during the follicular phase of the menstrual cycle. Thirty-five women with chronic schizophrenia who had minimal positive symptoms participated in this study. We evaluated the correlation of serum(More)
Antipsychotic-induced weight gain has important effects on treatment compliance and long-term health. Several reports have indicated that a -2548A/G single-nucleotide polymorphism (SNP) of the leptin gene is associated with antipsychotic-induced weight gain. We hypothesized that there is a similar relationship between the -2548A/G SNP and olanzapine-induced(More)
As the number of internet users increases, a new game genre using the internet as a networking tool is emerging. Some game genres are regarded as having greater addiction potentials than others. Games and the internet are closely related. We investigated games frequently used by adolescents and classified each of them with the help of game professionals. We(More)
BACKGROUND About 2% to 5% of all primary-care patients have a somatization disorder, and somatic symptoms are strongly associated with comorbid depression and anxiety disorders. OBJECTIVE The authors evaluated the validity of the 15-item Somatization module of the Patient Health Questionnaire (PHQ-15) among psychiatric outpatients. METHOD The PHQ-15 was(More)
