Active clinical trials for "Depression"

The purpose of the research is to study brain structure, function and chemistry of patients with bipolar disorder who are receiving quetiapine or lithium, in order to better understand who benefits from treatment and why they respond to medications.

It has been shown in the adult literature that smoking is related to depression and visa versa. Not much is known about how this relationship is started or if one perhaps leads to the other. We are performing 1 hour long interviews with adolescents ages 12-19 who meet criteria for major depression and who smoke. They are interviewed along with their parent. Questions center around their view of depression and their history of depression as well as questions around their smoking as well as the interrelationships between the two. Transcripts are made of the interview and are being analyzed for themes.

Observational, non-interventional, transversal, multicenter, open label (No treatment is involved). The primary objective is to detect the prevalence of depressive symptoms in bipolar patients admitted to a psychiatric Unit due to an acute mania episode. Secondary objectives include 1) to evaluate, the relationship between depressive symptoms and severity of mania; 2) to evaluate, the relationship between depressive symptoms and anxiety; 3) to evaluate, the relationship between depressive symptoms and psychotic symptoms; 4) to evaluate, the relationship between depressive symptoms and insight; 5) to evaluate, the relationship between depressive symptoms and clinical global impression; 6) to evaluate, the relationship between depressive symptoms and previous treatment with antipsychotics (whatever the antipsychotic was); 7) to evaluate, the relationship between depressive symptoms and length of admission; 8) to evaluate factors (demographic, evolution…) which could be involved in the presence of depressive symptoms within an acute manic episode; 9) to evaluate, the difference on the initial prescription due to the detection of depressive symptoms; 10) to evaluate, if exists, differences on the previous psychiatric diagnosis in patients with and without depressive symptoms. The primary endpoint is score of the MADRS (Montgomery-Asberg Depression Rating Scale) in bipolar patients with acute mania

The objective of the present research is to evaluate the incidence and independent predictors of delirium observed among patients after cardiac surgery. Moreover, to asses the sensitivity and specificity of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria (DSM-IV) and International Statistical Classification of Diseases and Health Related Problems - Tenth Revision criteria (ICD-10), and the cut-off values of the Memorial Delirium Assessment Scale (MDAS) and Delirium Index (DI) in diagnosing postoperative delirium.

Observational, non-interventional, longitudinal, prospective,multicenter, open label (No treatment is involved). 3 assessment will be carried out . The 1st one will be on baseline, the 2sd one after a significant change in pharmacological treatment and 3rd one after a second significant change in pharmacological treatment. If there isn´t any significant change in therapeutic plan a control assessment will be carry out in week 10th and 24th. A significant treatment change is defined as a change in SSRI/SNRI, to add another SSRI/SNRI or a augmentation treatment added to SSRI/SNRI. The primary objective is to describe therapeutical strategies (antidepressant change, association with another antidepressant or association with another treatment) in the management of patients with MDD with incomplete response or intolerance to an antidepressant after a first or a second failure; and when the psychiatrist decide a change of strategy. Secondary objectives include: 1 - To describe the clinic profile of depressive patients with incomplete response or intolerance to an antidepressant after a first or a second failure; 2- To describe the profile of patients based on therapeutic strategies used and number of therapeutic strategies; 4- Evaluate the use of health resource due to lack of fast onset of action, and social cost (productivity, care givers…); 5 - To associate clinical variable with therapeutic action by psychiatrist.

The purpose of this neuroimaging study is to investigate the brain correlates of Major Depressive Disorder with anxiety symptoms as well as potentially identify predictors of treatment outcome.

Since the primary damage from traumatic brain injury (TBI) is irreversible, the focus of medical management of TBI is preventing secondary injury that can be life-threatening and worsen patient outcome. Insight into the pathologic mechanisms of secondary injury, which are largely unknown, is required for developing better treatments. In preliminary studies, the investigators have found that a pathologic brain activity, known as spreading depression, recurs in a large number of TBI patients in the first week after injury. Spreading depressions are short-circuits of brain function that arise spontaneously from an injury and spread repeatedly as waves into neighboring brain tissue. Animal research has shown that spreading depressions can cause secondary injury to the brain. The primary objective of this observational study is to determine whether the occurrence or severity of spreading depression is related to worse neurologic recovery from TBI. Results from the study will determine whether monitoring of spreading depression should be used as a guide or target for improved medical management of the TBI patient.

Tools known as 'depression scales 'are widely used as assessments to evaluate a patient's response to treatment. The purpose of this study is the evaluation of the remission rates for patients with MDD. The evaluation will involve the use of HAM-D 17, and HAM-D 7 questionnaires and the comparison of those questionnaires.

The purpose of this study is to assess adolescents with Insulin Resistance Syndrome for quality of life and altered health related issues.

In usual clinical conditions, depressed patients with no sexual dysfunction, after signing their consent for the dissemination of their clinical information will begin their treatment with any SSRI or a Dual antidepressant as per the best clinical decision of their treating psychiatrist. Sexual dysfunction will be identified along the 6 months of active observation. Psychiatrists will decide to change dose, augment, shift or combine antidepressants at their clinical discretion in the benefit of their patients and all clinical decisions will be recorded.Comparisons among antidepressants will be made in terms of their sexual dysfunction potentiality.
