Effects of a Classic High-frequency rTMS Treatment Versus a Deep rTMS Treatment
Depressive DisorderTreatment-ResistantThe main objective is to demonstrate that dTMS is more efficient than high frequency rTMS with a conventional coil. The patient will receive treatment arm A or B : Arm A : classic rTMS treatment (use of the 8-shaped coil) and standard therapy Arm B: treatment with deep rTMS (use of the H-shaped coil (helmet)) and standard therapies. 20 rTMS sessions are planned (5 sessions per week) and 3 follow-up visits : at Day 30, Day 60 and Day 90.
PCS in Severe Treatment Resistant Depression
Treatment Resistant DepressionThis research study is designed to test if electrical stimulation of the surface of the brain in the frontal region will help treat depressive symptoms. Participants receive intermittent electrical stimulation to the brain, which involves surgically placing electric leads in between the tough fibrous membrane covering the surface of the brain and the surface of the brain itself. This type of stimulation is referred to as bilateral subdural prefrontal cortical stimulation (PCS) because it will specifically target the outer layer of the brain at the midline, right behind the forehead. It uses a pacemaker-like device, the Proclaim Elite SCS System (Abbott Laboratories) for stimulation. Although the U.S. Food and Drug Administration (FDA) has approved the system for brain stimulation for patients with chronic pain and muscular diseases, such as Parkinson's, its use is still investigational, and the surgery is still experimental for patients who have depression.

Dasatinib Plus Quercetin for Accelerated Aging in Mental Disorders
SchizophreniaTreatment Resistant Depression2 moreThis pilot open-label study examines the effects of a combination of dasatinib plus quercetin - two drugs that have known senolytics properties - on physiological aging in older individuals with depression or schizophrenia.
Ketamine Associated ACC GABA and Glutamate Change and Depression Remission:
Major Depressive DisorderTreatment Resistant Depression1 moreThis is a feasibility study and the goal of this project is to evaluate whether peak ACC GABA and glutamate, quantified as a CSF-corrected absolute concentration percent change from baseline, is associated with clinical remission, Montgomery Asberg Depression Rating Scale (MADRS) total score of <10, to the anti-glutamatergic antidepressant ketamine. As MRS is expensive, we also aim to study a correlation between change in peripheral metabolites (GABA and glutamate) and central GABA and glutamate levels.
Psilocybin-assisted Interpersonal Therapy for Depression
Depressive DisorderTreatment-ResistantThis is a single-arm, open-label interventional study of psilocybin-assisted interpersonal therapy for treatment resistant depression. 20 participants will be recruited to take part in this 8-week intervention that involves 8 sessions of psychotherapy and 2 doses of psilocybin.
DBS for TRD With the Medtronic Percept PC
Major Depressive DisorderTreatment Resistant DepressionOf the estimated 30 million Americans who suffer from Major Depressive Disorder, approximately 10% are considered treatment resistant. Deep brain stimulation (DBS) to a region of the brain called the subcallosal cingulate (SCC) is an emerging strategy for treatment resistant depression (TRD), which involves placement of electrodes in a specific region of the brain and stimulating that area with electricity. This is believed to reset the brain network responsible for symptoms and results in a significant antidepressant response. A series of open-label studies have demonstrated sustained, long-term antidepressant effects in 40-60% of patients who received this treatment. A challenge to the effective dissemination of this fledgling treatment is the absence of biomarkers (objective, measureable indications of the state of the body and brain) to guide device placement and select stimulation parameters during follow-up care. By using a DBS device called the Percept PC (Medtronic, Inc) which has the ability to both deliver stimulation to and record electrical signals directly from the brain, this study aims to identify changes in local field potentials (LFPs), specific electrical signals that are thought to represent how the brain communicates information from one region to another, to see how this relates to DBS parameter settings and patient depressive symptomatology. The goal of this study is to study LFPs before and during active DBS stimulation to identify changes that correlate with the antidepressant effects of SCC DBS. The study team will recruit 10 patients with TRD and implant them with the Percept PC system. Participants will be asked to complete short questionnaires and collect LFP data twice daily for the first year of the study, as well as have weekly in person research procedures and assessments with the study team for up to one year. These include meetings with the study psychiatrist, psychologist, symptom ratings, and movement, voice, and video recordings. A brief discontinuation experiment will be conducted after 6 months of stimulation, in which the stimulation will be turned off and patterns of LFP changes will be recorded. The entire study is expected to last about 5 years, parcellated into several study phases. All participants are required to live in the New York metropolitan area for the first several months of the study.
