Filter by: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.
The BrainDrugs-D study uses multimodal neuroimaging combined with self-report measures, clinical and molecular markers to identify clinically relevant predictors that can identify subtypes of major depressive disorder (MDD) and, in a naturalistic setting, predict treatment response to standard antidepressive treatment. The cohorts are followed in nationwide health registries.
The purpose of this study is to assess the effects of simultaneous administration of oral aspirin and oral ketamine as a therapeutic for those with Treatment Resistant Depression.
The investigators have developed an integrated suicide intervention, Brief Suicide and Trauma Therapy (BSTT). BSTT combines Brief-Skills for Safer Living (Brief-SfSL)-a promising method to enhance coping skills and reduce suicidality-with a trauma therapy component to alleviate the specific impacts of childhood trauma on suicide risk. The aim of this pilot is to test 12-weeks of BSTT to alleviate suicide risk among individuals with a history of childhood trauma and current suicidality.
At present, diagnosis and recognition of depression and bipolar disorder are mainly based on subjective evidence such as clinical interview and scale evaluation. The corresponding diagnosis basis has some shortcomings, such as poor diagnostic reliability and failure in early identification of bipolar disorder. Therefore, it is of great significance to explore objective diagnostic indicators to remedy the deficiencies. Thereforeļ¼the investigators collect psychological and physiological information data of patients with bipolar disorder and depression.Then the investigators aim to construct and verify the multidimensional emotion recognition model to analyze the personality characteristics, negative emotions and cognitive reactions of different individuals, and form a systematic accurate recognition and evaluation tool.
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.
Schizophrenia, bipolar and major depressive disorders collectively affect over 10 million people across the EU and are associated with annual healthcare and societal costs in excess of 100 billion Euros. When diagnosed with one of these disorders, patients are prescribed psychotropic medication such as antidepressants, mood stabilisers or antipsychotics. It is unknown whether this first-line treatment will be successful. After this first-line treatment fails, usually a second-line treatment is initiated, and when this is not successful either a third-line treatment is initiated. Third-line treatments are quite successful, especially when compared to second-line treatments. The research question is whether the third-line treatments (early-intensified treatments) would be more efficacious than the current second-line treatments (treatment as usual) for schizophrenia, bipolar and major depressive disorders. If this is indeed the case, this could lead to the prevention of unnecessary trials of ineffective treatments and adaptations of worldwide guidelines as well as a reduction of healthcare and societal costs.
Participants with depression will be given a single dose of psilocybin and supportive psychotherapy before, during, and after drug administration. Participants will undergo positron emission tomography (PET) imaging before and one week after psilocybin using a marker of synaptic density. This design allows us to assess the relationship between neurotrophic, and antidepressant effects produced by psilocybin.
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.
