Filter by:To evaluate the efficacy of SPD489 for the treatment of executive function impairments (EFI) when used as an adjunct to stable, standard therapy in the setting of partial or full remission from recurrent Major Depressive Disorder (MDD) as measured by the Global Executive Composite (GEC) T-score of the Behavioral Rating Inventory of Executive Functioning - Adult Version (BRIEF-A).
The purpose of this study is to provide a comparison of the apathy, depression, and functional outcomes associated with switching to duloxetine or escitalopram in patients who have previously responded to treatment with a selective serotonin reuptake inhibitor (SSRI) for major depressive disorder and who have residual apathy in the absence of depressed mood.
The purpose of this study is to find out what parts of the brain have increased or decreased connectivity when people are depressed and how Seroquel extended release (XR) changes this connectivity in depressed patients. The genetic samples collected are to look at variation in a gene (serotonin transporter gene), which affects the functioning of the chemical serotonin in the brain.
Depressive disorders are common in patients with Coronary Artery Disease (CAD), occurring in up to 47% of patients. Left untreated, these symptoms not only have a strong negative impact on quality-of-life, but also increase risk of future cardiac events and death. Unfortunately, about 64% of CAD patients do not respond to current antidepressant treatments. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are two omega-3 (ω-3) fatty acids found in fatty fish that are important for brain function. Recent evidence showed that depressed CAD patients have lower levels of EPA and DHA than non-depressed CAD patients. This information, taken together with the known roles of ω-3 fatty acids in brain function, suggests that deficiencies may contribute to depression. However, it is unknown if increasing consumption of ω-3 fatty acids would alleviate depression and improve quality of life. While intake of adequate levels of ω-3 fatty acids is difficult to obtain through diet, concentrated supplements containing EPA and DHA that are safe, readily available, and inexpensive are now obtainable in Canada. CAROTID (CAD Randomized Omega-3 Trial In Depression) will randomize patients with CAD, with and without depressive symptoms, after 6 months of cardiac rehabilitation and usual care to receive either ω-3 fatty acid supplements or placebo daily during their final 6 months of cardiac rehabilitation. The investigators hypothesize that CAD patients randomized to receive ω-3 fatty acid supplements will show greater improvement in depressive symptoms and quality-of-life over time. The investigators will also evaluate possible improvements in other important determinants of quality of life: memory and other cognitive abilities.
Major depressive disorder is a complex disease and most currently available antidepressants aiming at monoamine neurotransmission exhibit limited efficacy and cognitive effects. N-methyl-D-aspartate (NMDA), one subtype of glutamate receptors, plays an important role in learning and memory. N-methyl-D-aspartic acid (NMDA) enhancing agents, such as sarcosine (N-methylglycine), have been used as adjunctive therapy of schizophrenia. Sarcosine improved not only psychotic but also depressive symptoms in patients with schizophrenia. To confirm its antidepressant effect, the purpose of this study is to compare citalopram and sarcosine in efficacy for major depressive patients.
In this randomized, double-blind, multi-centre, placebo controlled, exploratory, adaptive design study, the antidepressant and plasma cytokine lowering effects of the GW856553 will be investigated in adult subjects diagnosed with MDD. Subjects will receive oral doses of GW856553 or placebo for six weeks. Safety, tolerability, pharmacokinetics and pharmacodynamics, defined as biomarkers in blood and clinical symptoms, will be assessed. The primary endpoint is the change from baseline associated with GW856553 versus placebo at Week 6 in the Bech (6-item HAMD-17) score. Interim analyses of the primary endpoint will be performed throughout the study to potentially adapt the study design by changing the randomization ratio and/ or reducing the total number of subjects to be randomized into the study. Exploratory analyses will be performed by associating changes in cytokine levels and selected clinical symptoms; PK/PD modelling will also be used to identify the most sensitive clinical and biological markers.
The purpose of this study is to assess the effect of treatment with Advair Diskus on depression using the Cornell depression scale in COPD patients in the nursing home.
The study investigates cognitive attention, rumination and psychophysiological (EEG) processes in healthy subjects and remitted patients with at least three previous depressive episodes. The investigators expect that Mindfulness Based Cognitive Therapy prevents future depressive episodes and has influence on cognitive and psychophysiological measures.
This two-center, between-subject, randomized, double-masked study (n=20) will provide the first evidence for the antidepressant efficacy of Magnetic Seizure Therapy (MST) and contrast the therapeutic properties and side effects of two forms of MST in patients in a major depressive episode (MDE).
RATIONALE: A computer-based system for assessing symptoms may be effective for patients with metastatic or advanced cancer. PURPOSE: This clinical trial is studying how well computerized questionnaires work in assessing symptoms, pain, depression, and physical function in patients with metastatic and/or advanced local/regional cancer.
