Phenotype Depression Study
Major Depressive DisorderTo facilitate the development of a personalized approach to the treatment of patients with major depression, this study is designed to elaborate the clinical and neurobiological phenotype of depressed patients with increased inflammation. The data obtained in this proposal will allow the investigators to test the hypothesis that depression and inflammation interact to elaborate a relatively discreet phenotype that warrants an individualized approach to diagnosis and treatment of patients with depression. Moreover, the identification of specific environmental risk factors for inflammation will foster the elaboration of preventative strategies for patients at risk.

MRI Study of Brain Activity and Risk for Depression in Adolescents
Involutional DepressionAnxiety DisordersAnxiety in children of parents with major depressive disorder (MDD) poses a particularly high risk for later-life MDD. In adults, MDD involves dysfunction in prefrontal brain regions that regulate attention to emotional stimuli. These abnormalities: i) have been found primarily in adults with specific familial forms of MDD; ii) persist after recovery from MDD, and iii) relate to anxiety. These findings raise the possibility that risk for MDD is tied to dysfunction in prefrontal regions involved in regulation of emotion, which possibly manifests as early-life anxiety. If this possibility were confirmed in never-depressed adolescents at high risk for MDD, the findings would provide key insights into the developmental neurobiology of MDD. The goal of this protocol is to study the neural substrate of risk for MDD in young people. This protocol tests the hypothesis that adolescents at high risk for MDD by virtue of childhood anxiety and parental history of MDD exhibit dysfunction in prefrontal cortex and amygdala, regions involved in emotion regulation. This goal will be accomplished through fMRI studies of emotion regulation in high and low-risk adolescents. For this research, at-risk adolescents will be recruited from participants in an NIMH-funded extramural study at New York University (NYU) examining the biology of risk for anxiety and depressive disorders. Over a three-year period, 45 high-risk probands and 60 low-risk comparisons will be studied, including 20 comparisons from the NYU sample and 40 from the Washington DC metropolitan area. In the present protocol, to be conducted at NIH, subjects will undergo volumetric MRI scans to assess structural abnormalities in the prefrontal cortex and medial temporal lobe. They will complete a series of four out-of-scanner cognitive tasks and two fMRI-based cognitive tasks that measure modulation of attention to emotional stimuli. The fMRI tasks are hypothesized to differentially engage the prefrontal cortex and amygdala in low vs. high risk subjects. These tasks will be used to test the hypothesis that at-risk individuals exhibit enhanced amygdala and reduced prefrontal activation on the fMRI emotion/attention tasks.
Prospective Study of the Evaluation of Disease contRol and the Quality of Life of Patients With...
DepressionAnxiety DisordersDepression is a psychiatric disorder that affects mood, thoughts and is usually accompanied by physical annoyances. It affects the person's eating habits, his sleep, the way he sees himself and the way he thinks and understands. Depressed emotion has great tension, lasts longer and leads to a reduction in the person's functioning in many areas of his life. Generalized Anxiety Disorder (GAD) is the psychiatric disorder characterized by a multitude of diverse organic responses as well as a generalized, persistent and indeterminate anxiety that covers almost all of the individual's activities. It is a diffuse and intense negative mood and anxiety that is present for most of the day and whose exact causes are often undetectable.

The Role of Inflammatory Processes in Development and Treatment of Depression
Depressive DisorderDepression1 moreThe study investigates the influence of inflammatory processes on the development and the course of uni- and bipolar depression. It is assumed, that the concentrations of certain inflammatory proteins have an influence on the development of depression, its clinical severity, the response to treatment and the risk of relapse. To verify this hypothesis, a total of 145 patients, which were hospitalized für treatment of a depressive disorder in the study centers in Germany, Italy and France, were screened according to the criteria set out in the study protocol. Finally, 104 patients with moderate to severe depressive symptoms were included in the study. These patients were treated according to the recommendations of the DGPPN treatment guidelines. All patients received a medication with sertraline or venlafaxine during the study, starting at baseline. The patients were examined for the presence and severity of depressive symptoms at the time of study enrollment, as well as after 4 and 8 weeks, using standardized clinical test procedures. In addition blood was taken. In the serum of the patients, the concentrations of specific inflammatory proteins were measured using Cytometric Bead Array (CBA) and Enzyme-linked Immunosorbent Assay (ELISA) and then correlated with the clinical data. The investigated proteins include high-sensitivity CRP (C-Reactive-Protein), Interleukin 4, Interleukin 6, Interleukin 12, tumor necrosis factor-α, Eotaxin, Intercellular adhesion molecule 1 (CD54), Interferone-gamma and monocyte chemotactic protein 1 (MCP-1).
