BACKGROUND Abnormalities in the prefrontal cortex have been implicated in the pathogenesis of major depressive disorder (MDD). To our knowledge, no prior study has examined prefrontal cortical anatomy in pediatric patients with MDD near the onset of illness before receiving treatment. METHODS Volumetric magnetic resonance imaging studies were conducted in 22 psychotropic-naive patients with M...
objective: the present study aims to investigate thought control strategies in generalized anxiety disorder (gad), major depressive disorder (mdd), and the relationship of these metacognitive strategies with trait anxiety, as a construct of emotional vulnerability. methods: 60 patients with diagnosis of gad and mdd and 30 control subjects (nonpatients) were selected from the university students...
OBJECTIVE Major depressive disorder (MDD) is a common mood disorder associated with several psychophysiological changes like disturbances of sleep, appetite, or sexual desire, and it affects the patients' life seriously. We aimed to explore a genetic method to investigate the mechanism of MDD. METHODS The mRNA expression profile (GSE53987) of MDD was downloaded from Gene Expression Omnibus da...
Replication has been poor for previously reported candidate genes involved in Major Depressive Disorder (MDD). One possible reason is phenotypic and genetic heterogeneity. The present study replicated genetic associations with MDD as defined in DSM-IV and with a more narrowly defined MDD subtype with a chronic and severe course. We first conducted a systematic review of genetic association stud...
OBJECTIVES To examine the demographic correlates of lifetime and 12-month prevalence of major depressive disorder (MDD) among older African Americans, Black Caribbeans, and non-Hispanic Whites. METHODS Data are from adults aged 55 years and older (n = 1439) recruited to the National Survey of American Life (NSAL; 2001-2003). The Diagnostic and Statistical Manual Version IV World Mental Health...
BACKGROUND The purpose of the study was to examine the association between family history of major depressive disorder (MDD) and mental health service utilization for MDD. METHODS Data come from wave 1 (2001-2002) and wave 2 (2004-2005) of the US National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The AUDADIS was used to determine the presence of lifetime and incident MD...
To assess the role of the purine nucleotide cycle in human skeletal muscle function, we evaluated 10 patients with AMP deaminase deficiency (myoadenylate deaminase deficiency; MDD). 4 MDD and 19 non-MDD controls participated in an exercise protocol. The latter group was composed of a patient cohort (n = 8) exhibiting a constellation of symptoms similar to those of the MDD patients, i.e., postex...
PURPOSE Emotional dysfunction is a hallmark of major depressive disorder (MDD). There has been wide interest in identifying the nature and significance of emotional deficits in MDD. Given the paramount goal of identifying etiological markers of MDD that can sharpen prevention and treatment efforts, researchers have pursued emotion as a functionally significant factor and predictor of clinical c...
Tryptophan hydroxylase-2 (TPH2) contributes to alterations in the function of neuronal serotonin (5-HT), which are associated with various psychopathologies, including major depressive disorder (MDD) or suicidal behavior. The methylation of a single CpG site in the promoter region of TPH2 affects gene expression. Suicide and MDD are strongly associated and genetic factors are at least partially...
Background & Aims: Schizophrenia and Major Depressive Disorder (MDD) are severe mental disorders and disturbances of immunity system are seen in their pathogenic process. Thus, in schizophrenia both general and specific components of immune system are disturbed. In MDD immunity system also changes. Numerous studies show that when depressed patients are exposed to allergen pollens, elevation of ...
