Filter by: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").
Single-center study to determine the relationship between changes in depression symptoms and electroencephalographic (EEG) patterns induced by electroconvulsive therapy (ECT)
The primary objective of this study is to evaluate the efficacy of psilocybin (25 mg) administered under supportive conditions to adult participants with severe TRD, in improving depressive symptoms.
The primary objective of this study is to evaluate the efficacy of 25 mg of psilocybin under supportive conditions to adult participants with BP-II, current episode depressed, in improving depressive symptoms.
The studies will be conducted in parallel at two sites: the the Mood and Anxiety Disorders Program at the Icahn School of Medicine at Mount Sinai (MSSM), and Stanford Depression Research Clinic at Stanford University School of Medicine (SUSM). In addition, MRI studies for the MSSM patients will be carried out at the New York State Psychaitric Institute (NYSPI). The following procedures will be approved by the local Institutional Review Boards (IRBs) at each site, where the site PIs (Alla Landa, PhD, NYSPI, James Murrough, MD at MSSM, and Alan Schatzberg, MD at SUSM) will be responsible for overseeing conduct of the study at their respective site. Dr. Jonathan Javitch is the scientific leader of this program and holds the IND for tianeptine use in this study. Investigators will recruit 75 participants with current unipolar MDD, non-delusional, between 21-60, who have failed at least 2 two adequate treatment trials with a standard antidepressant. Patients will receive an 8-week treatment trial of tianeptine. MSSM patients will also undergo structural and task-based magnetic resonance imaging (MRI) that will be performed under Dr. Landa's direction at NYSPI in order to maintain the internal validity of the data set. MSSM subjects will be transported to NYSPI to complete neuroimaging procedures as described below. Participants will be screened for MRI clearance during their screening visit and again at NYSPI on the day of the scan. Subjects will be asked MRI screening questions to ensure that are scanning eligible. Participants will also have additional tubes of blood drawn for human whole-genomic testing. This microarray will be used to identify regions of the human genome that contribute to disease susceptibility and phenotypes. The Illumina human whole-genome array will be used to provide a comprehensive view of the genome, detects single nucleotide polymorphisms and other variations across the genome.
This study evaluates an accelerated schedule of theta-burst stimulation using a transcranial magnetic stimulation device for treatment-resistant depression. In a double-blind, randomized, sham-controlled fashion, half the participants will receive accelerated theta-burst stimulation while half will receive sham treatment.
This study aims to openly test the long-term safety, tolerability and effectiveness of repeated administration of IV, nasal spray and oral ketamine for treatment-resistant mood disorders.
This is an open-label dosing pilot study of 15 patients aged 18-50 years of age with diagnoses of Major Depressive Disorder (MDD) randomized to 1 of 3 treatment arms. The study will consist of a screening evaluation performed within the course of 2 weeks, followed by an active treatment period of 28 days where treatment arm 1 will take a supervised dose of 300mg DXM every 14 days for 28 days, treatment arm 2 will take the FDA approved maximum daily ingestion for cough (60mg DXM) daily for 28 days, and treatment arm 3 will take 1 supervised dose of 300mg DXM and 60mg for the remaining 28 days. After the active treatment period, subjects will be followed for 65 days with safety and psychiatric assessments at designated timepoints.
Recent evidence suggest that Nitrous Oxyde (N2O) could exhibit antidepressant effect in treatment-resistant depression (TRD). However, the pathophysiology of this effect remains unclear and could include glutamatergic activity but also cerebrovascular effects and changes in brain connectivity. The goal of our study is to characterize brain reactivity to N2O in TRD patients, as assessed with Ultrasound Tissue Pulsatility Imaging (TPI) and Magnetic Resonance Imaging (MRI) (including Arterial Spin Labeling - ASL - for brain perfusion and Blood-Oxygen-Level Dependent - BOLD - for brain connectivity and pulsatility). Ultrasound and MRI Neuroimaging will be measured before, during and after a single one-hour exposure of a 50%N20/50%O2 mixture, in depressed individuals (n=20) and healthy volunteers (n=10). We make the hypothesis that brain reactivity will be lower in depressed individuals nonresponders to N2O compared to responders and healthy controls. This study would provide further characterisation of the pathophysiology of the antidepressant response to N2O, as well as providing potential biomakers (Ultrasound and MRI) for treatment response to N2O in TRD.
