Active clinical trials for "Depressive Disorder, Major"

This is a research study to examine the effectiveness of a brief screening method that may predict which people with posttraumatic stress disorder (PTSD) or depression are most likely to show a positive response to selective serotonin reuptake inhibitor (SSRI) medications. Participants will be recruited over approximately 5.25 years, until at least 94 participants complete the 17 week study.

This study analyzes the affects or Adderall extended-release (XR) in Subjects receiving brain stimulation therapy for the treatment of Major Depressive Disorder. Subjects will be assigned by chance to active or placebo group. Active group will be asked to take one 15 mg pill once daily of Adderall XR (amphetamine) and the Placebo group will be asked take an identical appearing tablet/capsule, one tablet by mouth daily. The placebo tablet has no active ingredients and has no affect on the body or mind. With the exception of the study drug, all other study activities between both groups will be identical. Subjects will use the assigned study drug two weeks before therapy and throughout the first 10 therapy treatments. A total of seven(7) visits will be required for screening, drug assignment, and completion of mood assessments. This study will enroll a total of 30 Subjects.

Develop a NIRSIT testing protocol that can be administered in the diagnostic setting and reliably distinguishes the symptoms and severity of depression, with the help of repeated measure (up to five visits per subject) comparison of patients being treated for Major Depressive Disorder with control, non-depressed subjects.

Co-occurring post-traumatic stress disorder (PTSD) and major depressive disorder (MDD) is the most common response to trauma; it is associated with poor clinical outcomes and substantial human disability. Veterans with both PTSD and MDD (PTSD+MDD) have been shown to be at much greater suicidal risk than individuals with only one of these disorders. Ketamine given as repeated infusions has been shown to be effective in rapidly reducing PTSD and MDD symptoms in treatment resistant PTSD+MDD individuals. However, knowledge about the mechanisms underlying comorbid PTSD and MDD remain limited. The purpose of this study is to use repeated ketamine infusions as a probe to validate a model of PTSD+MDD that focuses on neuroanatomy and executive functioning.

The Royal Canadian Mounted Police (RCMP), like all public safety personnel (PSP), are frequently exposed to potentially psychologically traumatic events that contribute to posttraumatic stress injuries (PTSI). Addressing PTSI is impeded by the limited available research. The RCMP are working to build evidence-based solutions to PTSI and other mental health challenges facing their members, which by extension will help all PSP, as part of the Canadian Government Federal Framework on Posttraumatic Stress Disorder. A key element is the "Longitudinal Study of Operational Stress Injuries / Étude longitudinale sur les traumatismes liés au stress opérationnel", a study which has been renamed "Risk and Resiliency Factors in the RCMP: A Prospective Investigation", and is referred to as the "RCMP Study" for short. The RCMP Study has been detailed online (www.rcmpstudy.ca) and in a recently published peer-reviewed protocol paper, "The Royal Canadian Mounted Police (RCMP) Study: protocol for a prospective investigation of mental health risk and resilience factors" (https://doi.org/10.24095/hpcdp.42.8.02). The RCMP Study, part of the concerted efforts by the RCMP to reduce PTSI by improving access to evidence-based assessments, treatments, and training as well as participant recruitment and RCMP Study developments to date. The RCMP Study has been designed to (1) develop, deploy and assess the impact of a system for ongoing annual, monthly and daily evidence-based assessments; (2) evaluate associations between demographic variables and PTSI; (3) longitudinally assess individual differences associated with PTSI; (4) augment the RCMP Cadet Training Program with skills to proactively mitigate PTSI; and (5) assess the impact of the augmented training condition (ATC) versus the standard training condition (STC). Participants in the STC (n = 480) and ATC (n = 480) are assessed before and after training and annually for 5 years on their deployment date; they also complete brief monthly and daily surveys. The RCMP Study results are expected to benefit the mental health of all participants, RCMP and PSP by reducing PTSI among all who serve.

This study apply a wearable visual device (HMD)-VR-based software medical device for patients with depressive disorder for 8 weeks. The investigator would like to confirm evaluate the safety and efficacy of the wearable visual device(HMD)-VR-based software medical device effect of improving depressive disorder in patients.

It is estimated that approximately 30% of child and adolescents manifest subthreshold depression, which can further develop into major depression with as high as 25%-50% within one year. The main aim of this trial is to investigate the effect of long-term exercise on preventing major depression and depressive symptoms in young people (aged 10-17 years old). Other aims include the underlying mechanisms of how aerobic exercise works and predictors for treatment response.

This study evaluates the effects of an accelerated schedule of theta-burst stimulation, termed Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), on the neural networks underlying explicit and implicit suicidal cognition in inpatients with major depressive disorder.

Severe mental illness (SMI) refers to the most burdensome psychiatric conditions. The need to pre-empt the onset of SMI is pressing because once SMI develops, quality of life is poor and available treatments have limited efficacy. Most risk factors for SMI are either unchangeable (e.g., genetics) or difficult to alter (e.g., low socio-economic status). In contrast, cannabis use is one specific risk factor that could be avoided. Certain individuals are more vulnerable to the harmful effects of cannabis. Genetic factors can help us identify these high-risk individuals. One in three individuals are carriers of a higher-risk genetic variant, and cannabis users with this genotype are at up to 7-fold increased risk of developing schizophrenia. In our study, genetic counselling will be provided to participants by a board-certified genetic counsellor. During the genetic counselling session, participants will have the option to receive their genotype. Participants will be counselled regarding their individualized risk of developing and of not developing SMI based on family history, whether or not they choose to use cannabis, and genotype (if the participants accept the genetic test results). The investigators hypothesize that this intervention will reduce exposure to cannabis compared to the youth who are not offered the intervention.

Major Depression is often resistant to treatment, and all of the currently marketed anti-depressants can cause significant side effects and may precipitate mania. The aim of this proposal is to perform a proof-of-concept RCT testing Palmitoylethanolamide (PEA) as a treatment for unipolar or bipolar depression, randomizing 100 patients to 6-week treatment with PEA 1200 mg/d or matching placebo. There are several rationales for this study: (A) PEA acts at the peroxisome proliferator-activated receptor-alpha (PPAR-α), stimulating Allo biosynthesis. Allo is an endogenous, positive allosteric modulator of GABA-A receptors in glutamatergic neurons, including cortical and hippocampal pyramidal glutamatergic neurons and may be one of the endogenous regulators of depression and anxiety. (B) Sage Therapeutics has developed Allo which is FDA approved to treat post-partum depression, and is testing a molecular modification which can be administered orally for post-partum depression and unipolar depression, with mixed efficacy results. Pregnenolone, a precursor of neurosteroids, has also been reported to improve bipolar depression. Based on animal models, PEA increases Allo synthesis in areas of the brain thought to be involved in anxiety and depression. It may also favor the biosynthesis of sulfated forms of Allo and congeners that inhibit tonic rather than phasic NMDA-mediated excitatory neurotransmission. Showing that PEA-induced selective inhibition of tonic NMDA neurotransmission improves depression might enable development of steroid-based NMDA-inhibitor therapeutics. In addition, PEA-induced Allo upregulation potentiates GABA-A receptor-mediated inhibition. The NMDA and the GABAergic mechanisms may act in concert to improve behavioral outcomes. Since PEA increases Allo in the brain where it is endogenously formed, it might be more effective compared with exogenous administration, which is not site specific. There is evidence of a role of inflammation in depression; PEA has potent immunoregulatory and anti-inflammatory effects by directly activating PPAR-α, which has a protective role against neuroinflammation by inhibiting the signaling mediated by toll-like receptor 4.There is one published study which shows that PEA has an antidepressant effect in unipolar depression, 58 patients were randomized to receive 1200 mg/d of PEA or placebo added-on to citalopram, showing clinical improvements in patients receiving PEA.
