Filter by:The investigators will test the hypothesis that inhaled xenon will produce a rapid improvement in depressive symptoms in patients suffering from treatment-resistant depression. Specifically, the investigators will conduct a parallel randomized, double-blind crossover study that will compare the effects of xenon-oxygen (35:65 ratio by volume) added to treatment as usual (X-TAU group) to the effects of nitrogen-oxygen (35:65 ratio by volume) added to treatment as usual (N-TAU group). A total of 20 severely depressed patients, 10 with major depressive disorder (MDD) and 10 with Bipolar Depression (BP), will be exposed in random order to N-TAU and X-TAU in a double-blind protocol.
Mexico, prevalence reported for major depressive disorder (MDD) is of 7.2%. It is currently in the top 5 causes of disability worldwide. One third of patients will not achieve remission after two treatments, being classified as treatment-resistant. In a neurochemical level, evidence shows dysregulation of the excitatory neurotransmitter Glutamate in patients with MDD. Chronic stress has been related to this dysregulation. Ketamine, has shown to regulate glutamatergic neurotransmission, and specially promote the release and production of neurotrophic factors key in the causes of MDD inhibited by glutamate dysregulation), and allow restoration of areas affected. Clinical studies of ketamine in MDD have shown robust, durable , and rapid effects (during the first 4-24 hours), allowing a great opportunity for patients who do not achieve benefits from antidepressants or patients with suicidal ideation . These results have been reported in metaanalysis. To our knowledge, there are no studies using Magnetic Resonance Spectroscopy, in areas related to MDD, after a series of ketamine administrations, which we think may show changes after this chronic administration and explain its antidepressant properties. Goals: Provide clinical evidence of responseas well as a neurological basis or biomarker of response to a series of ketamine infusions.
This study will examine the feasibility and efficacy of lifestyle medicine for the management of depression in Chinese adult population. The main components of lifestyle intervention typically include physical activity, diet, relaxation/mindfulness, and sleep. While lifestyle medicine has been recognized for centuries as a means to improve physical health, the field of lifestyle medicine in the context of mental health is still in its infancy. In the existing literature, there is increasing evidence demonstrating the efficacy of individual components of lifestyle medicine (e.g, physical activities and sleep) on depression. However, there is very limited research on the effectiveness of an integration of multiple lifestyle adjustments on depression.
The main aims of the study are to (1) compare the effectiveness of Group metacognitive therapy (GMCT) treatment to that of clinical management and (2) explore patterns of change and investigate factors associated with treatment outcome
This research tries to investigate the validity and reliability of eye-tracking technologies by using different paradigms (eg. free-view, pro-saccade and anti-saccade) which served as a novel way of evaluating suicide risk among affective disorder patients including bipolar and unipolar depression. All the participants including health control will be assessed by clinical interviewing, self-report assessment, cognitive evaluation and eye-tracking task.
This trial aims to assess the efficacy and tolerability of Magnetic Seizure Therapy (MST) and two different forms of electroconvulsive therapy (ECT) in sustaining response during and after a course of continuation treatment.
Depression is a frequent disease which can be marked by therapeutic resistance. It is described as one of the most disabling disease with high cost for society. World Health Organization pointed out that 350 million people are suffering from depression in the world. This pathology is considered underdiagnosed, with inadequate care resources and stigmatization. There is a wide range of evidence in current literature that anxiety is one of the most important factors involved in biological mechanism of treatment resistance in depression. To date, there is a lack of knowledge on this topic. A better understanding of the role of anxiety in the maintenance of depressive state will allow to i) identify quickly and more accurately patients at risk of pejorative evolution and ii) develop specific therapeutics targeting this dimension which remain badly controlled with actual therapeutics.
Background: Some women who had depression in the perimenopause may have mood symptoms again if they stop estrogen therapy. Estrogen acts in the brain and other tissues by binding to at least three types of estrogen receptors. One of these receptors, estrogen receptor beta may affect anxiety and depression. The drug LY500307 acts only on this receptor. In this study, researchers will initially give you estrogen and then suddenly stop estrogen after three weeks. Then they will study how LY500307 affects mood symptoms. Objectives: To study how withdrawing estradiol affects mood. To test the safety and side effects of LY500307. Eligibility: Healthy women ages 45-65 who had depression related to perimenopause in recent years and whose mood systems got better with estradiol Design: -Participants will be screened with: Medical history Physical exam Blood tests Psychiatric interview Gynecological exam - Participants able to get pregnant must use effective barrier birth control throughout the study. - During the first 3 weeks, participants will wear an estrogen patch. It is 1x2 inches and will be replaced every 3 days. - For the next 3 weeks, participants will take 3 study capsules every morning. They will not know if they get the study drug or placebo. - Some participants will also take a progesterone-like drug for 1 week at the end of the medication phase of the study. - Participants will have 9 one-hour study visits. They will have blood samples and vital signs taken. They will answer questions about mood and behavior symptoms. - Participants will keep a daily log of these symptoms. - Participants will have 2 transvaginal ultrasounds. A probe is temporarily placed 2-3 inches into the vaginal canal and sound waves are used to create pictures of the lining of the uturus. - Participants will have a final visit 4 weeks after stopping the study drug. They will answer questions about mood and side effects.
Testing and validating an e-health (smartphone application) approach to better understand the determinants of day-to-day symptomatology in depression, medication adherence, and treatment efficacy in the goal of maximizing patient care.
This project will combine the data collected from EEG, Eye tracking, structural and functional MRI scans and neuropsychological performance from patients with major depression receiving SSRI treatment. The purpose of this research is to predict the success of the SSRI treatment and to categorize patients into sub-groups according to similar patterns of brain activation to personalize treatment.
