Childhood adversities have been associated with onset and worse clinical presentations of depression. Epigenetic changes may reflect childhood adversities, while their effects on clinical characteristics of depression are unknown. This study aimed to investigate whether epigenetic changes were associated with childhood adversities, pretreatment(More)
Inflammatory cytokines have been implicated in the pathophysiology of depression, potentially underlying its association with worse physical health. Cytokine production is influenced by the transcriptional activity of several polymorphisms. We hypothesized that alleles related to higher proinflammatory and/or lower anti-inflammatory cytokine production(More)
OBJECTIVE Growing evidence suggests the separate associations of apolipoprotein E e4 allele (apo E4) and depression with incident dementia. This study investigated the separate and combined effects of apo E4 and depression on the incidence of dementia in both men and women. METHODS Of 625 elderly without dementia at baseline, 518 (83%) were followed over(More)
BACKGROUND Polymorphisms of serotonin transporter (5-HTT) and brain-derived neurotrophic factor (BDNF) have been investigated as candidate genes for post-stroke depression (PSD). Serotonin 2a receptor (5-HTR2a) genes have not been yet investigated in PSD. This study aimed to investigate whether the 5-HTT, 5-HTR2a, and BDNF genes are associated with PSD(More)
Depression is prevalent in patients with physical disorders, particularly in those with severe disorders such as cancer, stroke, and acute coronary syndrome. Depression has an adverse impact on the courses of these diseases that includes poor quality of life, more functional impairments, and a higher mortality rate. Patients with physical disorders are at(More)
BACKGROUND Increased physical activity may have beneficial effects on cognitive outcomes; a role of brain-derived neurotrophic factor (BDNF) has been suggested in animal models but not yet tested in humans. This study investigated modification by BDNF val66met polymorphism of the association between physical activity, incident dementia and other cognitive(More)
OBJECTIVES A cohort study of Japanese-American men suggested interactive effects of depression and apolipoprotein E (APOE) e4 allele on risk of incident dementia. In another sample of East Asian origin, we sought to replicate the findings and to explore individual depressive symptoms where this interaction was most evident. METHODS Of 625 Korean community(More)
OBJECTIVES Aripiprazole and ziprasidone are 2 antipsychotic medications that are relatively devoid of the metabolic adverse effects associated with the second-generation antipsychotics. This study aimed to evaluate the effectiveness of switching to ziprasidone in patients who had insufficient response or intolerance to aripiprazole for the treatment of(More)
This study aims to determine the effectiveness of paliperidone extended release (ER) on cognitive function in patients with schizophrenia in comparison with risperidone. This was a 12-week, randomized, open-label study on schizophrenia patients who were receiving risperidone. The patients were randomized to a risperidone-continuation group or a(More)
OBJECTIVES Brain-derived neurotrophic factor (BDNF) has been considered a risk factor for suicidal behavior in adult populations. BDNF secretion is influenced by epigenetic (DNA promoter methylation) and genetic (val66met polymorphism) profiles. We investigated the independent and interactive effects of BDNF methylation status and val66met polymorphisms on(More)
