Filter by:The purpose of this study was to demonstrate efficacy, safety and clinical benefit of Trazodone Contramid® OAD (Once A Day) in the treatment of Unipolar Major Depressive Disorder (MDD).
The primary objectives of this Phase II study are to demonstrate the safety of Nexalin Therapy and to investigate the efficacy of Nexalin Therapy.
The investigators intend to test in a single center, clinical pilot efficacy study the primary hypothesis that Magnetic Seizure Therapy (MST) as add-on therapy to a controlled pharmacotherapy is efficacious in the treatment of refractory major depression assessed with the Hamilton Depression Rating Scale (HAMD).
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.
This study will examine whether spring and fall seasonal depression in individuals with high sensitivity to pollen is linked to seasonal increases in tree and ragweed pollen.
This randomized, controlled clinical trial, the Low Vision Depression Prevention TriAL (VITAL), will test the efficacy of collaborative low vision rehabilitation (LVR) to prevent depressive disorders in Age-Related Macular Degeneration (AMD). In this innovative intervention, a low vision occupational therapist collaborates with a low vision optometrist to develop and implement a care plan based on a subject's vision status, rehabilitation potential, and personal rehabilitation goals. An independent rater masked to treatment assignment will assess depressive disorders meeting DSM-IV criteria (primary outcome) and targeted vision function and vision-related quality of life (secondary outcomes) at baseline and then at 4 months to evaluate short-term effects (main trial end point) and at 12 months to evaluate long-term effects.
Existing treatments for major depressive disorder (MDD) generally take weeks to months to exert their maximal benefit. There is an urgent need to develop rapid-acting treatments for MDD. Ketamine, a high-affinity N-methyl-D-aspartate (NMDA) glutamate receptor antagonist, has been used as a standard intravenous (IV) anesthetic agent for many years in both pediatric and adult patients. Beyond its well-established role in anesthesia and pain management, there is emerging evidence that ketamine may have rapid antidepressant properties for patients with severe mood disorders. In this study we are investigating whether ketamine can have an antidepressant effect compared to midazolam. Midazolam has similar anesthetic effects compared to ketamine but has not been shown to be an antidepressant, and is therefore acting as an active control in this study. The study period can last up to 8 weeks, depending on your response to the study medication. There are two required overnight stays in our Research Commons as part of this study.
Disturbances in the amino acid neurotransmitter (AANt), gamma-amino butyric acid (GABA) function are hypothesized to contribute to the neurobiology of Major Depressive Disorder (MDD) and insomnia. The principal objective of this project is to use magnetic resonance spectroscopy (MRS) to provide the first in vivo characterization of cortical GABA levels in individuals with primary insomnia, and to determine whether subjects with MDD, achieving a partial response with selective serotonin reuptake inhibitor treatment but still experiencing significant residual symptoms including insomnia, have altered levels of this neurotransmitter. The investigators are also exploring the correlation between cortical AANt levels and abnormalities in sleep parameters in primary insomnia and as a residual symptom of major depression.
Depression is a common illness with an approximate lifetime prevalence of 17 %, conferring a large burden of disease in the community, often due to inadequate treatment. Thus there is interest in the therapeutic potential of non invasive, novel forms of brain stimulation, such as transcranial direct current stimulation (tDCS). Two small studies have been published in the last two years indicating that 20 minutes of either 1 or 2mA tDCS over 5 or 10 sessions is safe, painless and well tolerated. The investigators' own pilot data (N=30) also suggests the technique has antidepressant effects and is safe (5-10 sessions of tDCS at 1 mA). This study will extend previous findings, testing a more definitive tDCS approach (also left prefrontal anodal stimulation) with a longer treatment course (15 sessions), at 2 mA (which has been found to be safe and more effective than 1 mA in cognitive studies), and in a larger sample (N=68), using a placebo-controlled design. It is hypothesised that active tDCS (15 sessions) will have greater efficacy than sham treatment (15 sessions) in reducing the severity of depressive symptoms in patients in an episode of major depression. A second hypothesis is that 15 sessions of tDCS will not cause any significant adverse effects or cause decline in neuropsychological functioning in comparison to a sham control.
S-adenosyl-L-methionine (SAMe) is a dietary supplement with antidepressant properties. SAMe's mechanism of action remains unclear, but it appears to be distinct from that of conventional antidepressants. The purpose of this study is to examine the effect of these properties on the mood of bipolar subjects with persistent major depression that has been unresponsive to standard pharmacotherapy.
