The study is investigating a link between high-risk plaque and cardioembolic sources among patients with stroke of unknown causes. This observational study uses an MRI protocol to detect bleeds within plaque, a marker of high-risk plaque. There is an additional PET/MRI that patients can opt into to more closely observe the plaque within the carotid arteries.

This study includes optional parts which will have financial compensation.

Newly diagnosed post-menopausal women with clinical stage II-III, HR+HER2- breast cancer are eligible for this randomized trial that will be concurrently open at five US academic institutions. Patients receiving 4 months of standard neoadjuvant hormonal therapy with letrozole are randomly assigned to one of 4 arms of the trial testing focal hypo-fractionated RT alone or with immunotherapy combinations. 

The purpose of this study is to investigate the relationships between neuroinflammation and Alzheimer’s disease (AD). Neuroinflammation is inflammation that occurs in the brain. Certain cells in the brain called microglia are involved in regulating inflammation. The accumulation of certain abnormal proteins, such as tau, have been implicated in AD. Tau may promote inflammatory reactions by microglial cells.

This study aims to compare the effects of 15 sessions (12 weekly in first 12 weeks and 3 monthly booster sessions afterwards) of PATH-MCI (Problem Adaptation Therapy for Mild Cognitive Impairment) vs. ST-CI (Supportive Therapy for Cognitively Impaired Older Adults). Participants receive either 15 weeks of PATH-MCI or Supportive Therapy. Research assessments will be conducted at entry into the study, 6, 12, 24, 36, and 52 weeks.

The purpose of this study is to evaluate physical reactions associated with PTSD that develops due to the experience of military sexual trauma.

We are conducting a randomized proof-of-concept study to assess the efficacy of virtual reality (VR) vs standard of care in 50 adult patients in the NewYork-Presbyterian Burn Unit. The participants who are randomized to receive the virtual reality intervention will also receive opioids, which is the standard of care and is known to be effective.

The purpose of this study is to treat symptoms of posttraumatic stress disorder (PTSD) resulting from burn trauma using traditional treatment. 

Military sexual trauma (MST) is defined as uninvited/unwanted sexual attention (such as touching, cornering, pressure for sexual favors, or verbal remarks), threat of or attempted 
sexual contact, sexual assault, or any sort of sexual activity between at least two people in which one of the people is involved against their will. This research is being done because MST has been identified as a pervasive problem with profound psychological and physical consequences.

Depression is the second leading cause of disability worldwide, due partly to the fact that existing antidepressants are not effective for all patients and it is often challenging to match individual patients to the treatments that are most likely to help them. This study will test a new strategy for using fMRI brain scans to predict antidepressant response and assist clinicians in choosing antidepressant treatments. Transcranial magnetic stimulation targeting one of two depression-related brain areas is most likely to benefit an individual patient. 

The goal of this study is to learn about changes in the brain of older adults that occur during treatment for depression with two types of psychotherapy called Engage therapy and supportive therapy, and how they differ from one another.

Engage therapy is designed to help individuals with depression become involved in activities they previously enjoyed but have not been participating in since developing depression. In Engage therapy, individuals with depression work with a therapist to develop "action plans" to pursue rewarding activities of their choice.
