The purpose of this study is to determine whether changes in sleep consolidation occur during home-based transcranial direct current stimulation (tDCS) in adults with moderate depression and whether these changes are temporally associated with improvements in depressive symptoms.

This study will seek to determine the (1) acceptability and (2) feasibility of psilocybin as an adjunct to cognitive-behavioral therapy, delivered as a group treatment (G-PACBT) for major depressive disorder and (3) explore the clinical effects of G-PACBT on depressive symptoms and psychosocial functioning.

Canada has one of the highest rates of multiple sclerosis (MS). MS patients experience disabling motor, visual, and sensory symptoms, and a high risk of comorbid major depressive disorder (MDD) and severe fatigue. The lifetime prevalence of MDD in MS patients is about 50%, and nearly 90% experience severe fatigue, both of which are not responsive to typical treatments. Repetitive transcranial magnetic stimulation (rTMS) is a first line, Health Canada approved non-invasive neurostimulation treatment for MDD. rTMS induces electrical activity in the cortex using magnetic fields generated outside of the head to drive neuronal firing in the target site. However, MS is typically an exclusion criterion due to safety concerns. The goal of this clinical trial is to learn if repeated transcranial magnetic stimulation (rTMS) can be used to treat depression symptoms in adults with multiple sclerosis (MS). rTMS is a non-invasive form of brain stimulation that uses magnetic pulses to stimulate specific parts of the brain. The main questions it aims to answer are: Is rTMS safe, tolerable, and feasible to deliver as a treatment for depression and fatigue symptoms in individuals with MS? Does rTMS show preliminary effectiveness in improving depression and fatigue symptoms in this population? Researchers will determine whether rTMS treatment improves mood, fatigue, and cognition across time points (baseline, after treatment, and 4-week follow-up). Participants will: Complete screening, questionnaires, clinical assessments, cognitive tests, a brain MRI to help tailor the TMS treatment, and receive daily TMS sessions for 5 consecutive days, including: Pre-TMS brain mapping, five rTMS treatments (3 minutes) per day, separated by one hour. A safety and tolerability questionnaire will be administered daily. Complete post-treatment assessments (questionnaires, cognitive tests, psychiatric evaluation). Complete a 4-week follow-up visit, in person or virtually. Wear a fitness tracking watch during the study so researchers can collect activity data remotely. About 20 people will take part in this study through the University of Calgary.

The goal of this clinical trial is to improve how electroconvulsive therapy (ECT) stimulation settings are chosen. Researchers will use real-time brain monitoring to measure both seizures and a recently identified brain event called cortical spreading depolarization (CSD). The main questions it aims to answer are: What is the best way to increase ECT stimulation settings? How do different pulse settings affect the brain's response? Can certain settings produce CSD without causing a seizure? Participants already receiving ECT as part of their care will take part. They will be assigned to one of two groups: Index ECT group: Participants starting ECT will receive different standard titration approaches. Maintenance ECT group: Participants receiving ongoing ECT will undergo a brief, low-dose stimulation test before treatment. All participants will be monitored using brain physiology (EEG and blood flow) and symptom scales during treatment.

The goal of this clinical trial is to determine if alpha phase-locked auditory stimulation can improve sleep in people with insomnia and depression. The main goals of the pilot study are the following: Determine whether alpha phase-locked auditory stimulation (active stimulation) improves objective and subjective sleep in individuals with insomnia and depression. The study team hypothesizes that active auditory stimulation will reduce objective and subjective sleep onset latency (SL) and wake after sleep onset (WASO) compared to a sham stimulation. Participants will: * Wear Elemind Neuromod headband nightly for 4 weeks (1 week baseline, 1 week active/sham stimulation, 1 week washout, and 1 week opposite condition - active/sham stimulation) * Wear actigraphy watch for duration of the study * Complete questionnaires regarding their sleep, mood, and satisfaction with the device

Purpose: Risk of severe psychopathology increases dramatically during adolescence, especially for females. Changes in ovarian steroids across the menstrual cycle produce windows of vulnerability to mood disturbances, particularly during the abrupt withdrawal of estradiol (E2) and progesterone (P4) prior to menses onset. Irrefutable evidence links stress with affective symptoms, potentially mediated by E2-related modifications of frontolimbic connectivity and prefrontal gamma-aminobutyric acid (GABA) inhibitory signaling. The primary objective of this project is to empirically test the impact of E2 and P4 change on vulnerable brain networks associated with irritability and other depressive symptoms in female adolescents at risk of suicide. Participants: The investigators will enroll 50 female adolescents ages 12-16 who are at risk of suicide (i.e., moderate depressive symptoms), and are eligible to receive oral contraceptives and undergo MRI imaging. Procedure: Using a randomized, placebo-controlled, cross-over design, participants will be studied under two conditions: 8 weeks of E2 and P4 stabilization (continuous combined oral contraceptive (COC) to prevent perimenstrual withdrawal) and 8 weeks of placebo, with a 1-month washout after each condition. Each condition will include: 1) daily samples of E2 and P4 urinary metabolites, 2) daily symptom ratings(e.g., irritability, negative affect and suicidal thoughts and behaviors (STBs)), and 3) a neuroimaging session with MRI and magnetic resonance spectroscopy (MRS).

This study tests whether a brain stimulation treatment for depression called intermittent theta burst stimulation (iTBS) can be improved by tailoring it to each individual. A type of brain signal measured with electroencephalography (EEG) after a single pulse of brain stimulation, called an early local TMS-evoked potential (EL-TEP), is used to identify which stimulation settings work best for each participant. The investigators will compare individualized (personalized) iTBS settings to standard (non-personalized) settings and to inactive (sham) stimulation. Participants are adults with treatment-resistant depression.

This study will look at how a new medication (dextromethorphan and bupropion taken together in one pill) affects the brain in people with depression. All participants will take the medication for two weeks and have brain scans done. Since people with depression often feel reduced enjoyment in day-to-day activities, our goal is to learn if this treatment can change brain activities in ways that could help improve mood and enjoyment in life.

The purpose of this study is to primarily assess the feasibility and secondarily assess the efficacy of a single session intervention (SSI) that combines non-invasive brain stimulation and psychotherapy for Major Depressive Disorder (MDD). investigators will recruit 30 people with MDD, with at least mild to moderate symptoms, who are resistant to typical treatments for Major Depressive Disorder. In this trial, participants will receive psychotherapy, Intermittent Theta Burst Stimulation Transcranial Magnetic Stimulation (iTBS), and either active or sham (placebo) Transcranial Alternating Current Stimulation (tACS).

The purpose of this study is to determine the safety and clinical effectiveness of a shortened lysergic acid diethylamide (LSD) experience. This will be achieved by administering the drug risperidone 45-minutes after the administration of LSD.

The proposed study aims to establish the feasibility and safety of subcutaneous tocilizumab, a monoclonal antibody (mAb) against interleukin (IL)-6 receptor, in adults with Major Depressive Disorder (MDD) and evidence of peripheral immune activation. IL-6 is a pro-inflammatory cytokine implicated in the pathophysiology of depression. The investigators hypothesize that neutralizing peripheral immune signaling via IL-6 receptor blockade with tocilizumab will improve neural and behavioral measures of reward processing. This is an open-label, proof-of concept, trial in which up to N=20 adults with MDD meeting a specific immune enrichment criterion will receive open-label tocilizumab over 8 weeks. A healthy control (HC) group (N=20) will undergo baseline neuroimaging and blood-based biomarker assessment without receiving the study drug to aid interpretation of findings. Blood-based immune markers and brain MRI scans (including task-based reward activation and resting-state functional connectivity) will be assessed at baseline for all participants and again post treatment for the MDD group.

The goal of this clinical trial is to assess the feasibility of nutritional interventions in college students with depression. The main outcomes it aims to measure are: * Nutritional content, meal timing, and sleep patterns in college students with depression * Feasibility of nutritional interventions (Mediterranean Diet and Time-Restricted Eating + Mediterranean Diet) in college students with depression Researchers will compare two groups - Mediterranean Diet (Med-Diet) and Time-Restricted Eating + Mediterranean Diet (TRE + Med-Diet) - to assess adherence to the dietary interventions and overall feasibility of the study procedures. Participants will: * Complete a 2-week baseline logging diet, sleep, activity, and mood * Be randomized to Mediterranean Diet (Med-Diet) or Time-Restricted Eating + Med-Diet (TRE + Med-Diet) * Participate in dietary counseling with a registered dietitian during the 8-week intervention * Continue to log diet, wear an actigraphy device, and complete mood, sleep, and diet assessments throughout the intervention
