This pilot study will collect preliminary data that measures the effects of psilocybin-assisted psychotherapy vs ketamine-assisted psychotherapy on patients struggling with alcohol use.
This multi-site, double-blind, randomized, sham-controlled mechanistic trial aims to test the effects of Magnus Neuromodulation System (MNS) with Stanford Accelerated Intermittent Neuromodulation Therapy (SAINT®) Technology on the neural circuitry of suicidal cognitions in psychiatrically hospitalized patients with Major Depressive Disorder (MDD) and active suicidal ideation (SI). This will be accomplished by applying the MNS with SAINT to a customized target within the left dorsolateral prefrontal cortex (L-DLPFC) identified with fMRI for five consecutive days and measuring resting-state functional connectivity (RS FC) between the subgenual anterior cingulate cortex (sgACC) and the default mode network (DMN) at baseline and immediate-post visit. The relationship between changes in RS FC and changes in both Explicit and Implicit Suicidal Cognitions (ESC and ISC, respectively) will be determined. This study will also determine the relationship between changes in RS FC in neural networks underlying mediators of suicidal cognitions and changes in such mediators with active versus sham SAINT.

The purpose of this study is to examine the effects of interventional/procedural therapies for treatment-resistant depression (TRD) and Obsessive-Compulsive Disorder (OCD). These treatments include electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), racemic ketamine infusion and intranasal esketamine insufflation. The investigators will obtain various indicators, or biomarkers, of a depressed individuals' state before, during, and/or after these treatments. Such biomarkers include neurobehavioral testing, neuroimaging, electroencephalography, cognitive testing, vocal recordings, epi/genetic testing, and autonomic nervous system measures (i.e. "fight-or-flight" response). The results obtained from this study may provide novel antidepressant treatment response biomarkers, with the future goal of targeting a given treatment to an individual patient ("personalized medicine").
The overall objective of this current study is to evaluate the feasibility, safety, and tolerability of "high dose" aiTBS in psychiatric inpatient and outpatients with treatment-refractory unipolar, non-psychotic major depressive disorder, using patients receiving ECT as an active comparator. Developing a better understanding of the feasibility and tolerability of adapting this treatment to an acutely ill patient population could lead to huge breakthroughs for clinician decision-making and for the further optimization of brain stimulation depression protocols. The results of this study can help guide future confirmatory efficacy trials of high-dose aiTBS by providing a better understanding of how feasibility, safety and tolerability compare to ECT, as well as unforeseen challenges of its use.
