Filter by:The purpose of this study is to examine the effects of vilazodone for the treatment of depression in older adults.
Primary Objective: - To evaluate the effects of two fixed doses of SSR149415 (250 mg bid and 100 mg bid) on hypothalamic-pituitary-adrenal axis function in patients with major depressive disorder. Secondary Objectives: - To evaluate the tolerability and safety of SSR149415 in patients with major depressive disorder. - To evaluate the efficacy of two fixed doses of SSR149415 compared to placebo in patients with major depressive disorder. - To evaluate plasma concentrations of SSR149415.
The purpose of this study is to see if creatine, which is a naturally occurring chemical in the body, is effective for treating Major Depressive Disorder (MDD) in female teenagers. The primary hypothesis is that compared to placebo, 2g, 4g, and 10g of creatine monohydrate for eight weeks will be associated with a significant increase in brain phosphocreatine (PCr) concentrations.
Patients with an episode of depression in late life prescribed mirtazapine recruited from a clinical sample will be monitored for weight and receive a blood test during their usual course of treatment to determine polymorphisms in a specific gene (LEPR) thought to affect weight gain.
The purpose of this study is to understand the effectiveness of a ten-week internet-based cognitive behavioral therapy (iCBT) treatment on improving depressive symptoms, coping and resilience skills, and cognitive processing.
The primary aim of this application is to conduct a randomized, controlled clinical trial of a specialized mental health service delivery system specifically developed for prodromal psychotic disorders. The intervention is Family-aided Assertive Community Treatment (FACT). The goal of the treatment is prevention of psychosis and disability. This study will assess experimentally the clinical effectiveness of this new type of mental health service. Other domains of outcome include cognitive dysfunction and functional disability.
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 purpose of this study is the evaluation of remission rate between escitalopram 20 mg and 30 mg in patients with major depressive disorder.
Numerous factors can influence the processing of pain message: the affective or emotional, the sensorial and the cognitive components. Interindividual variations at the emotional and cognitive levels may interfere with the pain message and the consecutive behavior. Some modifications in these components are observed in psychiatric troubles, but their influences on the behavior to pain have not been studied, although they have been studied in some populations characterized as non communicating, with obvious cognitive degradations (subject with dementia, older, newborns,…).In an other study in course, the past pain experience is explored in relation to results to experimental pain tests, emotional and anxious characteristics. This present pilot study aims at studying the infra-verbal behavioural signs during experimentally induced pain in subjects with schizophrenia, major depression, and controls.
This pilot, open label investigation evaluates the safety and efficacy of a new form of electroconvulsive therapy (ECT). Both the efficacy and adverse cognitive effects of ECT are highly contingent on the intracerebral current paths and current density of the ECT stimulus. However, the impedance of the skull and individual differences in skull anatomy severely limit the spatial targeting of stimulation, and create marked individual differences in intracerebral current density. To address these problems, the investigators are exploring various means of overcoming this limitation. An approach is to modify the electrical stimulus to induce focal seizures. The most common methods of ECT administration in the US use a bidirectional, constant current, brief pulse, with large (approximately 3 sq. in. surface area) and identically sized and shaped electrodes. In contrast, in this protocol the investigators have coupled unidirectional current flow with an electrode geometry involving a small and large electrode that differ by more than 3:1 in surface area. Unidirectional currents were widely used in ECT during the, 1940's and continue to be used in European and American devices today. Transcranial electrical stimulation can be made focal by stimulating with an anode-cathode arrangement, with the electrodes differing in surface area. The investigators have shown in nonhuman primates the capacity to produce focal frontal seizure induction under conditions when a unidirectional current flows from a small anterior anode (placed on the forehead over the nasion) to a large posterior cathode just anterior to the motor strip. Furthermore, the investigators expect that some, if not all, of these seizures do not result in motor convulsions. Thirty outpatients referred for ECT will participate. Relative to concurrent reference data from our ongoing ECT protocols, the investigators hypothesize that acute and subacute adverse cognitive effects of FEAST will be substantially less than those in patients receiving state-of-the art ECT, but with a traditional bidirectional, nonfocal stimulus. The investigators also hypothesize that the majority of patients will remit with FEAST. Thus, by improving the efficiency of the ECT stimulus with the switch to unidirectional current and the use of a new electrode geometry, the investigators expect to be able to induce focal seizures. The investigators hypothesize that this pilot study will provide evidence that this treatment is superior to traditional ECT in having lower dosing requirements and a superior side effect profile.
