Filter by:The purpose of this study is to test the antidepressant effects of Ezogabine in major depressive disorder (MDD). The investigators also aim to determine the safety and tolerability Ezogabine in patients with MDD. The investigators hypothesize that depressive symptoms will be significantly decreased following an 8-week treatment period of the medication compared to baseline.
Depression is a leading contributor to global burden of disease. Antidepressants do not provide adequate response for many patients. Mind-body therapies are often safe, increasingly embraced by patients, however good quality clinical trial data is limited. The PI has shown that there is autonomic instability in patients with late life depression (LLD). Through his team of across discipline researchers he will investigate benefits of one adjunctive mind-body intervention, automatic self transcending meditation on autonomic instability in LLD and depressive symptoms compared to treatment as usual. If results are positive, such an intervention could be used for management of LLD across all levels of care. WHAT IS THE INNOVATION AND MAIN QUESTION/HYPOTHESIS UNDERLYING THIS PROPOSAL? The main study objectives are to assess heart rate variability (HRV), other autonomic parameters and depression scores in patients with late life depression undergoing an innovative mind-body therapy 'automatic self-transcending meditation' (ASTM) not previously evaluated in a randomized controlled manner in the treatment of late life depression. It is expected that adding ASTM to TAU will be better than TAU in improving HRV, depression severity and other autonomic parameters in the treatment of LLD. It is expected that this intervention will produce significant anxiolytic and enhanced quality of life outcomes and will have no major side effects. If the results of this study are positive, it is possible that this intervention could be considered as treatment option for the management of this disabling illness in primary, secondary and tertiary care. Such treatment option would be more cost and staff effective, and self empowering than the current standard of care. It could also provide treatment options for patients who are currently resistant to their antidepressants.
Major depressive disorder (MDD) is a significant public health problem. Existing treatment modalities are not always sufficient to alleviate this disorder. Treatment refractoriness is a common clinical problem. Transcranial direct current stimulation (t-DCS), a non-invasive brain stimulation technique, has been shown to be effective in alleviating depressive symptoms in preliminary studies. There is need to explore the role of t-DCS in Treatment-resistant depression (TRD). Therefore, the investigators aim to undertake this exploratory study. Aim: Compare the role of left prefrontal cortex anodal t-DCS daily stimulation of 4 weeks (20 week days) with sham stimulation in alleviating depressive symptoms in patients with TRD. Methodology: Patients who seek treatment in our treatment resistant depression clinic and who have failed to respond to treatment with two antidepressant medications will be offered to enroll in this study. The aim is to study 20 patients who meet the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) criteria for MDD between the ages of 21-65 years. Those subjects that receive sham stimulation will be offered to have active t-DCS stimulation for additional 3 weeks to get any benefit that they may have otherwise missed by being in the sham stimulation group. Results and Conclusions: The investigators will compare the mean baseline and end of treatment Montgomery Asberg depression rating scale between the two groups. The investigators will compare the change in mean depression scores between the baseline and end of treatment in those receiving active t-DCS for a total of 7 weeks duration. This study is innovative and of significance in exploring the role of this novel, easy to administer, safe and cost effective treatment modality.
This is a 52-week open-label study to evaluate the safety and tolerability of ALKS 5461.
Major depressive disorder (MDD) is a global medical problem with significant shortcomings in current therapy. Chief among these is the delay between initiation of pharmacologic therapy and clinical improvement in symptoms. Recently ketamine, an NDMA-receptor antagonist has been shown to rapidly and effectively reverse the symptoms of MDD. Nitrous oxide, another NMDA-receptor antagonist, may produce the same effect with a cleaner side-effect profile and perhaps without the need for intravenous access and anesthesia personnel. Therefore, we propose conducting a pilot randomized placebo controlled double-blind crossover study in which patients will receive up to 50% nitrous oxide in oxygen or up to 50% oxygen in air for a period of one hour in addition to standard medical therapy. Depression severity will be assessed by a blinded observer pre-treatment, 30 minutes and 2 hours post treatment using the Hamilton depression rating scale.
The primary hypothesis is that compared to placebo, 10g of daily creatine monohydrate for eight weeks will be associated with significant increases in frontal lobe phosphocreatine and beta-nucleoside triphosphate (β-NTP) concentrations. A secondary hypothesis is that decreased depressive symptoms measured with the Children's Depression Rating Scale-Revised (CDRS-R) and Montgomery-Asberg Depression Rating Scale (MADRS) will be reciprocally correlated with increased β-NTP concentrations.
The purpose of this study is to evaluate the efficacy of intranasal esketamine 84 milligram (mg) compared with intranasal placebo along with standard care treatment, in reducing the symptoms of major depressive disorder (MDD) (an affective disorder manifested by either a dysphoric mood or loss of interest or pleasure in usual activities, the mood disturbance is prominent and relatively persistent), including the risk for suicide as assessed by the Investigator, in participants who will be assessed to be at imminent risk for suicide.
Major depressive disorder (MDD) is a highly prevalent, chronic and/or recurrent condition with substantial morbidity and mortality. It is one of the leading causes of disability worldwide. Despite significant advances in pharmacological treatment for depression over the last two decades, a significant proportion of patients (10-20%) are resistant to currently available treatment. The development of new effective treatment for depression is limited by the fact that MDD is a heterogeneous disorder with subgroups based on variations in etiological factors and treatment response. Functional magnetic resonance imaging (fMRI) approaches offer promise in the prediction and evaluation of clinical response of antidepressant treatment. Previous fMRI studies have identified increased activity in dorso-lateral prefrontal cortex (DLPFC) and decreased amygdala activity from the baseline as imaging markers of antidepressant response in patients with MDD. However, these studies have examined MDD as a homogenous group without specifying the type of patient group, and brain regions as a priori hypothesis.We therefore need studies using combined genetics and neuroimaging measures as biomarkers in the prediction and evaluation of clinical response to antidepressants. In this study we attempted to determine imaging clinical efficacy markers in previously defined brain regions (amygdala and prefrontal regions) for two classes of antidepressants (citalopram and quetiapine extended release (XR)) with differential action on serotonin transporter inhibition in a subgroup of MDD patients with high risk allele ( S/Lg) of serotonin transporter gene polymorphism.
High frequency repetitive transcranial magnetic stimulation (HF-rTMS) has shown safety and efficacy for treatment-resistant depression, but requires daily treatment for 4-6 weeks. Accelerated HF-TMS (aHF-rTMS), in which all treatments are delivered in less time, would have significant advantages in terms of access, patient acceptance and costs. In the present open label trial the investigators intend to assess the effectiveness and acceptability of a novel aHF-rTMS protocol (i.e., 2 daily sessions over 2 consecutive weeks; 6,000 pulses per day). For this, depressed outpatients will receive the aHF-rTMS protocol and will be assessed at baseline and at weeks 3 and 9 with several clinician- and patient- reported measures as well as with computerized neurocognitive tests.
The study will investigate functional and metabolic changes in the course of antidepressive treatments. The investigators will apply different imaging methods to investigate the effects of antidepressive interventions on resting state neural activity, functional activation during cognitive and emotional stimulation, neurotransmitter concentrations as well as concentrations of brain- derived neurotrophic factor.
