Filter by:This open-label functional Magnetic Resonance Imaging (fMRI) study will assess the effects of a single dose of psilocybin on rumination and the neural correlates of rumination in individuals with major depressive disorder.
The objective of this clinical trial is to explore the potential impact of dietary polystyrene microplastics on anxiety- and depression-like behaviors in resident physicians. Specifically, the study aims to address two key questions: 1. Can dietary polystyrene microplastics induce alterations in the human gut microbiome? 2. Can dietary polystyrene microplastics exacerbate anxiety- and depression-like behaviors? Participants will be divided into two groups based on their habitual eating practices: The control group, consisting of resident physicians, will use non-disposable plastic tableware (NDPT) provided by hospital canteens for two months. In contrast, the exposure group, also comprising resident physicians, will use disposable plastic tableware (DPT) made of polystyrene, provided by the same hospital canteens, over the same period.
This study will compare two psychological treatments for major depressive disorder (MDD): cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT). Both treatments are well-studied and supported by evidence as effective options for people experiencing depression. These treatments will be delivered in an online group format via Zoom. The study will enroll up to 150 participants with depression. Half of the participants will receive online group CBT and half will receive online group ACT. There will be up to 10 members in each group. For both conditions, treatment will be provided over 8 weeks, with a 6-month follow-up period. Enrollment will be ongoing and groups will occur simultaneously. Potential participants are asked to complete an initial screening and an intake evaluation to determine eligibility. They will then receive 8-weeks of treatment. Participants will complete self-report questionnaires throughout their time in the study.
This study experimentally investigates 1) whether ultra processed food (UPF) intake contributes to depression by increasing low mood and poor sleep due to blood glucose fluctuations (which then increases the desire to consume more UPFs) and 2) to investigate the effectiveness of a 2-week meal-kit intervention that provides convenient and tasty minimally processed foods (MPF) to reduce depression. The following aims and hypotheses are tested: Aim 1: To investigate whether UPF intake and low mood contribute to each other in a cyclical fashion through the mechanisms of blood glucose fluctuations and disrupted sleep in individuals with moderate-to-severe depression. H1: It is hypothesized that UPF intake and high blood glucose will be associated with low mood in individuals with depression. Aim 2: To establish an industry partnership to investigate whether commercially available meal kit delivery reduces symptoms of depression in individuals with moderate-to-severe depression relative to a nutrition education control condition. H2: Meal kit delivery will lead to reductions in depression symptoms and daily reductions in low mood relative to the control condition (nutrition guidance only).
The goal of this pilot Study and Randomized Controlled Trial is to investigate the impact of electroacupuncture on cognitive function, quality of life (QoL), and depression severity in patients with major depressive disorder (MDD). The main question[s] it aims to answer are: - Primary : electroacupuncture has the potential to treat subjective cognitive complaints and cognitive impairment in MDD outpatients - Secondary : electroacupuncture has the potential to treat depressive in MDD outpatients The 60 participants will randomly be assigned to either the treatment group or the control group in a 1:1 ratio. The treatment group will undergo electroacupuncture (EA), while the control group will receive sham acupuncture within 10 weeks period. Both groups will receive antidepressants with adjunctive medication (i.e., benzodiazepines, tricyclics, or antipsychotics) as the standard treatment. All participants will be assessed for executive functions and memory using specific cognitive tests, including the Trail Making Test B (TMT-B), Stroop Color and Word Test (SCWT), category delayed recall in the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), and subjective reports of concern regarding concentration, memory, problem-solving, learning, communication, and quality of life (QoL) concerns using the WHO Disability Assessment Schedule (WHODAS 2.0; sections D1.1-1.6 and H1-3), and depressive symptoms were assessed using the Thai-PHQ-9.
This study aims to identify how enhanced allopregnanolone activity (via pregnenolone) affects behavior and neurobiology that may underlie perimenopausal depression.
The results of ketamine, ketamine and midazolom and placebo can be copied after birth in cesareans subjected to spinal anesthesia.
The aim of this Phase 2a study in patients with MDD is to assess safety and tolerability and preliminary antidepressant efficacy.
The researchers are trying to test the feasibility and acceptability of using transcranial Direct Current Stimulation (tDCS) in hospitalized adult patients with Treatment Resistant Depression (TRD), assess for any preliminary effect on depressive and cognitive symptoms, and explore the utility of biomarkers to assess response to tDCS.
This study will evaluate the efficacy and safety of SPN-820 in Adults With Major Depressive Disorder (MDD)
