Cannabidiol for Treatment Resistant Depression
Treatment Resistant DepressionWith this study, the investigators will address the following scientific aims: Demonstrate the antidepressant effects of CBD in human adults with treatment refractory MDD as measured by standard rating scales. Confirm CBD's safety profile in human adult patients with MDD.

ECT vs. Esketamine
Treatment Resistant DepressionMajor Depressive DisorderTreatment-resistant depression (TRD) is a common cause of disability and one of the most common psychiatric disorders worldwide. Electroconvulsive therapy (ECT) is currently the most effective treatment for TRD. Recent developments showed esketamine to be a rapid-acting and effective antidepressant drug and it has been hailed as a breakthrough in treating TRD. Common treatment algorithms for TRD list ECT as a treatment option, but esketamine has not yet found its exact position in those algorithms. To the investigators' knowledge, a longitudinal, randomized controlled trial comparing the efficacy of ECT and intranasal esketamine in TRD patients has not been conducted. Furthermore, the investigators intend to measure effects of ECT and intranasal esketamine on brain connectivity and structure, using functional magnetic resonance imaging (fMRI). In this study, inpatients with TRD at the University Hospital for Psychiatry I, Medical University Innsbruck, will be randomized to ECT or intranasal esketamine. Short- and medium-term treatment effects on functional and structural connectivity in the brain will be determined using fMRI.

Low-dose S-ketamine in Women With Prenatal Depression
Prenatal DepressionKetamine1 morePrenatal depression is an important risk factor of postpartum depression. Low-dose ketamine has been used for depression treatment. As a stereoisomer of ketamine, s-ketamine has similar effects to ketamine in anti-depression. We speculate that, for pregnant women with prenatal depression, low-dose s-ketamine infusion after childbirth may reduce the incidence of postpartum depression.

Effect of SSRIs on Response to Psilocybin Therapy
DepressionMajor Depressive Disorder3 moreThis study is an open-label, single-arm, within-subjects design in individuals with mild-moderate Major Depressive Disorder (MDD). All participants will receive a single dose of 25mg of psilocybin in a therapeutic setting. In order to investigate the effects of length of time on SSRI therapy, 30 participants with varying lengths of time on SSRI therapy will be enrolled, stratified into four groups: Group 1: ≤ 1 year Group 2: 1 to ≤ 5 years Group 3: 5 to ≤ 10 years Group 4: > 10 years

PET Synaptogenesis After Psilocybin In DEpression Recovery
Major Depressive DisorderAnhedoniaParticipants 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.

Sustainable Upscaling of Depression Prevention
DepressionResearch shows that online unguided self-help interventions focused on psycho-education, skills training and lifestyle can prevent mild mood complaints from turning into a full-blown depression. These encouraging results are found even though the adherence to these types of interventions is generally low. With this project, the investigators examine whether adherence to online unguided self-help interventions can be increased by additional motivational guidance elements and as such further improve the effectiveness. This is examined by adding three additional components to the intervention: 1) A coach who provides online feedback once a week to provide support. 2) Mobile application to monitor mood and related factors and to receive automated personalized messages, 3) Content based on the principles of motivational interviewing. A secondary aim is to compare the additional effects of the individual components against the additional costs.

Applying the Spanish Version of the UP-A as a Universal School-based Anxiety and Depression Prevention...
AnxietyDepressionThe current study proposes to extend transdiagnostic treatment research to adolescents by establishing initial pre to post-treatment and follow-up outcomes associated with the use of the Spanish Version of the Unified Protocol for the Treatment of Emotional Disorders in Adolescents (UP-A; Ehrenreich-May, Bilek, Buzzella, Kennedy, Mash, & Bennett, 2016) as a universal school-based preventive intervention.

Comparing the Effectiveness of Clinicians and Paraprofessionals to Reduce Disparities in Perinatal...
Perinatal DepressionPostPartum DepressionThere is considerable evidence that most perinatal women at risk for postpartum depression do not engage in mental health services, even when referred by home visiting (HV) programs, primary care physicians, obstetricians, or gynecologists. Thus, interventions that can be delivered via alternative settings-e.g., HV programs-are essential to prevent the onset of major depression and worsening of depressive symptoms among perinatal women. This Patient Centered Outcomes Research Institute (PCORI) funded project aims to evaluate whether the Mothers and Babies (MB) group intervention, when led by paraprofessional home visitors, is more efficacious than usual care (i.e., home visiting without the MB enhancement). It will also examine if MB, when led by paraprofessional home visitors, is not inferior to MB delivered by mental health professionals. The results of this study will inform decision-making by HV programs regarding provision of MB to perinatal women at risk for developing major depression.

Effect of Exercise on Perinatal Depression
PregnancyPostpartum Period1 moreFifteen percent of women experience depression during pregnancy or postpartum (i.e., perinatal depression). Furthermore, 38% of low income women experience postpartum depression. Given few women with perinatal depression seek treatment, there is a need for innovative, low cost interventions that can be integrated within existing community-based programs serving women in need (e.g., low income women). The primary aim of this study is to examine the efficacy of a novel exercise intervention designed to prevent perinatal depression among women attending federally qualified health centers serving high risk women.

e-PAT Neuromod Evaluation of Personalized rTMS for Resistant Depression
Depressive DisorderTreatment-ResistantAlthough repetitive trans-cranial magnetic stimulation (rTMS) is an effective therapy for resistant depression, it still fail to remit up to 70% of these patients. We hypothesize that personalizing the procedure using functional MRI to better select dysfunctional regions and robotic coil placement to stimulate these regions homogeneously, will increase its efficacy. Individualized rTMS will be compared to traditional rTMS procedure and to trans-cranial direct current stimulation (tDCS). In this small proof of principle study our primary outcome measure will be the correction of the MRI anomalies. Symptoms reduction and the proportion of remitters will be secondary outcome measurements.
