Active clinical trials for "Depressive Disorder"

The purpose of this study is to learn if measures of brain activity are different in children and adolescents with depression who are in different stages of treatment. This is important because it may identify a biological marker for depression that could one day be used to identify depressed children who would benefit from certain treatments (medications for example), or to monitor how well treatments are working. Brain activity measures(known as cortical excitability and inhibition) will be collected by Transcranial Magnetic Stimulation (TMS). TMS is a noninvasive (no surgery or implants) brain stimulation technology which can make parts of the brain work without putting any wires or chemicals into the body. Measurements will take place over one 3-hour visit. This study does not provide any form of treatment. *There is an optional portion of the study that uses a brain scan to gather measures of brain structure and brain chemicals. The brain scan is called magnetic resonance and spectroscopy (MRI/MRS). MRI/MRS uses magnetic fields to study the structure of the brain and brain chemicals. The PI will determine eligibility for the MRI/MRS portion of the study.

The aims of this prospective, observational study are to assess the current use of depression care in Coronary Heart Disease (CHD) patients, and to provide estimates for the resources needed to implement guideline-oriented depression health care acceptable to CHD patients with comorbid depression.

The primary objective of this study is to investigate the biological components of major depression. The investigators are particularity interested in genetic variation and how it contributes to cortisol (because cortisol is higher in severe depression than mild depression or healthy controls) and how it contributes to clinical symptoms, especially suicidal ideation/behavior and psychosis.

PRODE is a Norwegian multicentre study investigating the prognosis of depression in the elderly. The study has included 169 patients who will be followed with assessments after one and three years. The study hypothesis is that elderly patients referred to specialist health service have a poor long term prognosis.

This study aims to investigate reward learning across the mood disorder spectrum and to investigate the predictive validity of reward learning for subsequent symptom severity.

This randomized clinical trial studies how well minocycline hydrochloride works in reducing chemotherapy induced depression and anxiety in patients with stage I-III breast cancer. Minocycline hydrochloride may prevent changes in memory and thinking and improve the quality of life of breast cancer patients receiving chemotherapy.

The purpose of this retrospective observational study is to evaluate the characteristics of patients receiving Seroquel XR as treatment for their Major Depressive Disorder. The study will also investigate how the medication is used for these patients and if there are any differences in drug utilisation between the included countries. The study is observing patients initiating Seroquel XR during a 9 month period corresponding to 3 to 12 months following the launch of the product in each country for the MDD indication. A drug utilisation questionnaire will be used to collect study data from patients' medical records.

The main objective of this study is to compare the rate of reported anxiety / depression (HADS >= 8) among spouses and other family members in ICU patients.

Complex Dynamic Systems in Mood Disorders is an observational, exploratory study of the relationship between voice samples, heart rate, respiration, movement, galvanic skin conductance, and sleep architecture with mood states in patients with Major Depressive Disorder, Bipolar Disorder, and healthy controls. The overall hypothesis is that nonlinear dynamic analyses will be able to reveal hidden patterns of complexity in each domain of voice, heart rate variability, movement, arousal, and sleep stage data.

Depression in patients with schizophrenia is common. Several factors was found to be associated with depression including medical illness, quality of life, positive symptoms, and typical antipsychotics. The Calgary depression scale of schizophrenia (CDSS) is commonly used for screening depression in schizophrenia,however; the Thai version of CDSS has not been validated. This study aims to a.) test the reliability and validity of the Thai version of Calgary depression scale of schizophrenia (CDSS) and b.) identify the prevalence and factors associated with depression in patients with schizophrenia including quality of life, type of antipsychotic drugs, and severity of schizophrenia in 60 patients with schizophrenia at the Faculty of Medicine, Chiang Mai University, Thailand.
