Unconscious Reduction of Fear Through Decoded Neuro-Reinforcement

Phobia

This application investigates the efficacy of a novel method of neuro-reinforcement based on decoded fMRI activity to reduce fear responses in individuals with phobias (e.g., spiders, snakes). This method works unconsciously in the brain, without the need for participants to endure repeated conscious exposures to their feared stimuli. Fear-related disorders such as specific phobia, post-traumatic stress disorder (PTSD), and other anxiety disorders present a major challenge, as effective treatment options usually involve repeated exposures to feared stimuli, leading to high levels of distress, fear, and panic that can motivate premature treatment termination. Consequently, there is an unmet need for treatment that minimizes subjective discomfort and attrition in order to maximize efficacy. Recent developments in computational neuroimaging have enabled a method that can deliver unconscious exposure to feared stimuli, resulting in effective fear reduction while bypassing a primary cause of treatment attrition. Because this treatment method happens unconsciously in the brain, changes in behavior outcomes are potentially more likely to generalize to different contexts, thereby overcoming a limitation of traditional treatments.

Cognition and Behavior With Sham Accelerated TMS

Depression

The goal of this clinical study is to understand how a person's expectations about treatment can influence their mood, motivation, and reactions to everyday rewards. The study includes young people ages 15-25 who will complete a sham (placebo) version of an accelerated transcranial magnetic stimulation (TMS) treatment. No active brain stimulation is given. The main questions this study aims to answer are: 1. Do expectancy and treatment beliefs change during and after an accelerated sham TMS schedule? 2. Do these expectations influence mood, reward processing, or craving? 3. Does a more intensive schedule of sham sessions lead to different expectancy effects than a slower, once-daily schedule? Participants will: * Complete baseline clinical assessments and an MRI session * Undergo five days of accelerated sham TMS (no active brain stimulation is delivered) * Complete post-treatment MRI and follow-up assessments at 1 week and 4 weeks

Mindfulness Engaged Neurostimulation for Depression (MEND II)

Depression ยท Treatment Resistant Depression ยท Major Depressive Disorder

Repetitive Transcranial Magnetic stimulation (rTMS) is an FDA-approved therapy for treatment resistant depression (TRD) that involves brief magnetic stimulation pulses on the dorsolateral prefrontal cortex (DLPFC) brain region. But studies of rTMS alone show remission rates of \~30%. Additionally, rTMS has not been shown to improve cognitive functioning that may be an independent factor predicting treatment success. This study will develop a novel multimodal treatment, which combines intermittent theta burst stimulation (iTBS) - a type of rTMS with digital mindfulness training to engage brain plasticity, enhance cognition and alleviate depression symptoms in individuals with TRD.

Intracranial Neurophysiological Signatures of Fear and Anxiety in Humans

Fear ยท GAD ยท Emotional Memory

Anxiety disorders such as post-traumatic stress disorder (PTSD) and generalized anxiety disorder (GAD) affect a large number of individuals with a significant portion of patients failing to improve with current treatments. The purpose of this study is to understand the brain mechanisms that produce fear and anxiety in humans. To accomplish this goal, we will measure the brain activity along with the heart rate and skin perspiration of patients while they are completing tasks on a computer. Some of the tasks will also use a virtual reality headset and transport the patient in a video game-like environment. These tasks will expose the participants to various levels of fear-provoking images. Participants with responsive neurostimulation (RNS) implants will be enrolled under Pro00117931 at Duke, but their results for fear and anxiety tasks will be reported under NCT05120635.

The BEAR Program for Women With Trauma Who Have Suicidal Thoughts

Interpersonal Trauma ยท Depression ยท PTSD

The current study aims to test the feasibility of a new form of group therapy for women who have a history of interpersonal trauma and current suicidal ideation. The Building Empowerment and Resilience (BEAR) Therapeutic group has been adapted for women who have experienced trauma and have current suicidal ideation. It incorporates psychological skills, psychoeducation about trauma and gender-based violence, and physical self-defense training, all within a therapeutic process. It will be implemented with women who have experienced interpersonal trauma (physical, sexual, or emotional abuse/neglect) and experience various mental health difficulties, including suicidal ideation. We aim to assess the feasibility to recruit and implement the BEAR group. Our ultimate aim is to assess whether the program can effect self-efficacy and suicidal ideation.

Accelerated Intermittent Theta Burst Stimulation for Adolescent and Young Adult Depression With Elevated Suicide Risk

Major Depressive Disorder (MDD) ยท Suicidal Ideation

The goal of this clinical trial is to learn if a fast-acting brain stimulation treatment called transcranial magnetic stimulation (TMS) can help people with depression and suicidal thoughts. The treatment is non-invasive (does not involve surgery or medications), is given over 5 days, and uses brain imaging (MRI) to guide which part of the brain to target. This study tests whether this treatment is a helpful and practical option for adolescents and young adults who are depressed and have suicidal thoughts. We want to see if: 1. This treatment is feasible and acceptable to patients 2. It can reduce depression and suicidal thoughts 3. It can lower the chance of going to the hospital 4. It affects daily functioning (school, work, relationships) All participants will undergo 5-days of TMS treatment and complete MRI brain scans before and after treatment. They will return for check-ups after 1 week and 4 weeks.

Pupillometry in Identifying Risk of Postoperative Opioid-induced Respiratory Depression in Children Undergoing Tonsillectomy

Opioid-Induced Respiratory Depression ยท Postoperative Complications (Cardiopulmonary) ยท Respiratory Complications Due to Anesthesia

This study will evaluate whether quantitative pupillometry measurements can be used to identify children at risk for postoperative opioid-induced respiratory depression (OIRD) following tonsillectomy. Opioid-induced respiratory depression is a serious and potentially life-threatening complication that can occur after surgery, and current monitoring approaches are limited in their ability to predict which patients are at highest risk. In this prospective observational cohort study, approximately 300 pediatric patients undergoing tonsillectomy will undergo non-invasive pupillometry measurements at defined perioperative time points, including preoperative, intraoperative, and postoperative periods. Pupillometry measurements will be collected using a commercially available, FDA-regulated infrared pupillometer. These measurements will include pupil size, constriction and dilation velocities, and latency in response to light stimulation. Pupillometry data will be collected for research purposes only and will not be used to guide clinical care or treatment decisions. Standard clinical care will not be altered as part of this study. Clinical outcomes, including the occurrence of postoperative opioid-induced respiratory depression, opioid use, sedation levels, pain scores, and other postoperative events, will be recorded from the medical record. The goal of this study is to evaluate the relationship between pupillary response patterns and the occurrence of postoperative respiratory depression, and to support the development of predictive models that may improve early identification of patients at risk for opioid-related adverse events.

Investigating the Neural Mechanisms of Repetitive Brain Stimulation With Invasive and Noninvasive Electrophysiology in Humans

Major Depressive Disorder ยท Epilepsy

Transcranial magnetic stimulation (TMS) is an effective treatment for depression, but clinical outcome is suboptimal, partially because investigators are missing biologically-grounded brain markers which show that TMS is modifying activity at the intended target in the brain. The goal of this proposal is to characterize the key markers of the brain's response to repeated doses of TMS with high resolution using invasive brain recordings in humans, and relate these brain markers to noninvasive recordings. These markers will improve the understanding of TMS and can be used to optimize and enhance clinical efficacy for depression and other psychiatric disorders.
