The goal of the study is to examine the extent to which exposure to the SUPPORT prototype increases community health workers' (CHWs) knowledge, skills, and self-efficacy to conduct effective outreach to minority women experiencing the menopausal transition. The investigators will collect quantitative, pretest and posttest survey data from adult CHWs.

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.

Many people with depression do not get better with standard treatments like medication. One promising alternative is transcranial magnetic stimulation (TMS), a non-invasive procedure that uses magnetic pulses to stimulate specific brain regions. A particular pattern of TMS called continuous theta-burst stimulation (cTBS) is thought to reduce overactive brain activity in depression, but the investigators do not yet fully understand how it works at the level of brain cells and connections. This study aims to determine the biological mechanism by which cTBS changes brain activity in people with depression. Specifically, the investigators are testing two competing ideas: (1) that cTBS works by weakening the connections between brain cells through a process called long-term depression (LTD), which is driven by a chemical messenger system called glutamate; or (2) that cTBS works by increasing the brain's natural "braking" system, driven by a different chemical messenger called GABA. To test these ideas, participants with depression will receive cTBS along with one of four FDA-approved medications, or placebo, that either boost or block these chemical messenger systems. The investigators will measure changes in brain activity using electroencephalography (EEG) recorded simultaneously with TMS. Specific patterns in the EEG signal, called TMS-evoked potentials (TEPs), act as a window into how different brain cell types are responding to stimulation. Each participant will complete four study visits, each testing a different drug-TMS combination in random order. One group of participants will test drugs targeting the glutamate system (d-cycloserine and memantine). A second group will test drugs targeting the GABA system (lorazepam and baclofen). All drugs are given as a single oral dose and are commonly used in clinical practice. Understanding exactly how cTBS works at a biological level could open the door to more effective, personalized TMS treatments.

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).

The purpose of this study is to find out if patients with prostate cancer who have vasomotor symptoms, commonly called hot flashes, from their Androgen Deprivation Therapy (ADT) will consistently wear a smartwatch device to track their health data, log hot flashes on their smartwatch, and how these data compare with daily surveys about their hot flashes. Participants will be asked to wear the smartwatch for 4 weeks and to log their hot flashes on their smart watch pressing a button on the watch. Participants will be asked to complete surveys (sent through a text message link) to describe their experiences with hot flashes.

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.

Repetitive Transcranial Magnetic stimulation (rTMS) is an FDA-approved therapy for treatment resistant depression (TRD) that involves brief magnetic stimulation pulses on the dorsolateral prefrontal cortex (DLPFC) brain region. But studies of rTMS alone show remission rates of \~30%. Additionally, rTMS has not been shown to improve cognitive functioning that may be an independent factor predicting treatment success. This study will develop a novel multimodal treatment, which combines intermittent theta burst stimulation (iTBS) - a type of rTMS with digital mindfulness training to engage brain plasticity, enhance cognition and alleviate depression symptoms in individuals with TRD.

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.
