Filter by:This study looks at the role of the Nociceptin/Orphanin FQ receptor system in the brain of individuals with current or past major depressive disorder (MDD). It also examines how individuals with a history of depression make certain decisions and which brain regions are involved in such decisions. Information collected through MRI, PET, biospecimens (i.e., blood, saliva) and behavioral tasks will be used to predict depressive symptoms in the future.
For patients with treatment-resistant depression (TRD), a single low dose of intravenous (IV) ketamine can help relieve symptoms as quickly as 24 hours later. The main problem with IV ketamine for TRD is that the effect is short-lived, lasting only days to 1 or 2 weeks. Furthermore, IV ketamine is a resource-intensive treatment, and the safety of long-term, repeated use for depression is unknown. To provide this treatment in a safe and cost-effective way, Investigators must allocate it efficiently to those patients who have the greatest need and probability of benefit. Therefore, this project aims to find clinical features (signs, symptoms, and parts of a patient's history) that will help predict which patients are most likely to respond to a single dose of IV ketamine for TRD. This will help guide patient selection and triaging. Investigators will recruit 40 participants with TRD over one year, and randomize them to one of two conditions (ketamine followed by an active placebo 3-weeks later, or vice versa). With clinical data collected through detailed interviews, questionnaires, actigraphy, speech sampling, electroencephalography (EEG), and computerized tasks, this study design will let us evaluate how well such factors predict (A) rapid response at 24-hours, and (B) sustained response at 7 and 14 days.
Major depressive disorder (MDD) is a common mental illness that severely affects the health and quality of life of patients. Treatment with acupuncture alone or a combination of appropriate adjuncts has been reported to be significantly effective in reducing the severity of MDD, relieving patients' somatic symptoms and improving sleep. This study will focus on the intradermal acupuncture, which is more convenient, gentler and has longer lasting effects. The aim is to study the efficacy and safety of intradermal acupuncture for MDD, and to preliminarily explore the central nervous mechanisms by which it exerts its therapeutic effects.
Differentiation between major depressive disorder (MDD) and bipolar disorder (BD) as soon as possible in the patient journey represents a major clinical issue. When the patient is in a depressive phase, the symptoms are similar between the two pathologies and the current clinical scales fail in distinguishing them. Physicians often report this difficulty and as a consequence, the mean time from onset to bipolar disorder diagnosis is currently 7.5 years. These diagnostic delays and misdiagnosis lead to damaging consequences for patients and their loved ones: worsening of symptoms, comorbidities, suicide risk and inadequate care resulting in severe impairment in social and occupational functioning. Faced with these high expectations for accurate diagnostic methods for an earlier management of psychiatric patients, the combination of relevant clinical features and biomarkers could stand for a solution, leading to a personalised approach in patients with mood disorders. In a first clinical discovery study, a panel of RNA biomarkers in the blood of patients with a major depressive episode (MDE) has been identified, allowing to differentiate bipolar disorder from MDD (unipolar depression). These biomarkers are based on RNA modifications, namely RNA editing, that could be identified using molecular biology, NGS and artificial intelligence. This panel constitutes EDIT-B test, which is based on Alcediag's proprietary and patented biomarkers and algorithms. The present study aims to validate the biomarker signatures proposed by Alcediag by measuring the association between the modifications of the RNA editing and major depressive disorder/ bipolar disorder diagnosis, in patients with a MDE in real-life setting pilot centres.
Patients, physicians, and those who fund depression research are keenly interested in depression treatments that do not involve taking medications. One promising candidate treatment is transcranial direct current stimulation (tDCS), a low-cost technique that involves placing electrodes on specific scalp locations and using a 9-volt battery to cause a small amount of electricity to pass through parts of the brain. Depending on the direction of electrical flow, tDCS can make brain cells (neurons) more likely or less likely to generate their own electrical signals. When evaluated as a treatment, tDCS is typically done in daily sessions over a period of two weeks. One of the challenges of tDCS is to work out the best possible positioning of electrodes and direction of electricity flow to gradually cause lasting changes in brain activity in ways that might be expected to improve depression. To address this challenge, the investigators are using MRI to take pictures of the brain during tDCS. This data will help us better understand the short-term effects of tDCS in depression and help us learn how to customize future treatments to cause a lasting beneficial response. Patients with depression between the ages of 20-55 years are eligible to take part in this research. Potential participants will undergo: 1. An assessment to confirm eligibility. This will take place over a secure videoconference call lasting no more than 3 hours. 2. Two in-person study visits lasting 30 min and 2-1/2 hours respectively. In the first visit, the investigators will use the MRI to take a picture of the brain and head structure to determine appropriate locations for placing the tDCS electrodes at the start of the second visit. Following electrode placement, an MRI scan will be performed to take pictures of the brain during tDCS. Depending on the study arm, 1. Participants may receive 'active' or 'sham' tDCS. The 'sham' condition is identical to the 'active' tDCS in every way except that it involves minimal tDCS and is designed to help rule out effects unrelated to the administered tDCS electricity. 2. Participants may also be asked to perform a mental task during MRI. All participants will be compensated $150 + parking upon completion of all study-visits.
This is a Phase 2/3, Multicenter, Randomized, Double-blind, Placebo-controlled Trial of the Safety and Efficacy of Flexible Doses of SEP-363856 as Adjunctive Therapy in the Treatment of Adults with Major Depressive Disorder (MDD)
The goal of this clinical trial is to investigate if the drug D-Cycloserine (DCS) improves the antidepressant effects of Intermittent Theta Burst Stimulation (iTBS), a non-invasive brain stimulation therapy, in patients with Major Depressive Disorder (MDD). The main questions it aims to answer are: - Whether taking DCS prior to iTBS therapy will be more effective in improving depressive symptoms than iTBS therapy alone. - Compare the effect of DCS 100mg/day versus 50mg/day on depressive symptoms. - Test the safety and tolerability of DCS. Participants will take either 50mg DCS per day, 100mg DCS or placebo prior to each iTBS treatment session. iTBS treatment will be administered daily, 5 days a week for 4 weeks. Clinical measures will be conducted at baseline and at the ends of weeks 1, 2, 3 and 4 of treatment.
This experiment intends to explore the differences among various types of depression, as well as the differences between healthy subjects and depressed patients, and find possible biological markers from the severity of symptoms, social function and cognitive function of depressed patients, combined with EEG characteristics, biological test indicators (blood, faeces, hair, etc.) and functional magnetic resonance imaging data. To explore the changes in clinical symptoms, cognitive and social functions, and biological indicators of various types of patients before and after treatment, to provide references for the prognosis of various types, and to predict the future development of the disease according to the baseline indicators of patients; According to the above aspects, this experiment can follow up the patients with depression, track their disease development, and study the potential biological changes in the early stage of the disease, which has the potential to reveal the pathogenesis and provide guidance for the early diagnosis and intervention of depression.
The purpose of this study is to establish how personalization of repetitive transcranial magnetic stimulation (rTMS) can change markers of brain activity and improve treatment response. To do this, all participants will receive the same active form of treatments, but some of the participants in this study will receive intermittent theta burst stimulation (iTBS) rTMS treatment with standard forms of targeting and intensity, and others will receive iTBS rTMS treatment using personalized magnetic resonance imaging (MRI) and electric field (E-field) modeling measures.
Measurement-based care (MBC) is an evidence-based practice that incorporates routine outcome assessment using validated rating scales to guide collaborative clinical decision-making. Although MBC results in improved outcomes for patients with major depressive disorder (MDD), there are barriers to its broad implementation in clinical settings. The use of "enhanced" MBC (eMBC), with mobile apps that allow patients to track outcomes and engage in self-management via WeChat, may address some of these barriers. This study intends to compare differences of efficacy between the implementation with eMBC using WeChat and the standard MBC implementation using paper-pencil assessments at the clinic, for both implementation and clinical outcomes.
