The purpose of this study, entitled "Psychological trauma, post-traumatic stress disorder, and resilience in adults with congenital heart disease in a large population sample", is to evaluate for exposures during a lifetime with congenital heart disease that may be associated with higher likelihood of developing PTSD. Primary aim: - Identify individual patient characteristics (medical, psychosocial, socioeconomic, etc.) that are associated with a diagnosis of PTSD. Secondary aims: - Calculate the prevalence of those meeting PTSD criteria in the ACHD population using the "gold standard" diagnostic clinician interview, while using the same data to validate a PTSD screening self-report survey in the ACHD population. - Determine the role of resilience in ACHD patients using a validated screening survey to assess its protective role toward PTSD. Hypotheses: - There are certain exposures (e.g. post-surgical pain, ICU delirium, bullying due to CHD) that are associated with a higher incidence and odds of meeting PTSD criteria. - "Gold standard" diagnostic interviews will most accurately estimate the prevalence of PTSD in ACHD which has been overestimated on prior screening-based studies, although the scope of the problem is still great. - Patients with a higher resilience score will show an association with a lower risk of PTSD.

Individuals with depression often describe difficulties with memory, attention, concentration, and overall cognitive functioning, which can persist even after mood episodes get better, and can affect treatment and health outcomes. The primary objective of this pilot clinical trial is to evaluate the feasibility and acceptability of a manualized, 8-week, Compensatory Cognitive Training (CCT) intervention for Veterans who received treatment for MDD in the past year and have persistent cognitive functioning deficits. The investigators will compare Motivationally Enhanced Compensatory Cognitive Training for Major Depressive Disorder (ME-CCT-MDD) to a robust comparator, Goal-focused Supportive Contact (GSC), to evaluate differences in outcome measures. The investigators hypothesize that Motivationally Enhanced Compensatory Cognitive Training for Major Depressive Disorder (ME-CCT-MDD) will be feasible and acceptable to participants in a pilot trial of ME-CCT-MDD vs. Goal-focused supportive contact (GSC) for Veterans with recent MDD treatment and persistent cognitive symptoms. This study will also evaluate the preliminary magnitude and direction of symptom change on measures of objective cognitive functioning, psychiatric symptomatology, psychosocial functioning, and quality of life. The investigators hypothesize that CCT will improve objective cognitive functioning, psychiatric outcomes, psychosocial functioning, and quality of life in Veterans with recent MDD-related cognitive functioning deficits. Participants who agree to participate in the study will: 1. Take part in an assessment of their cognition, symptoms, and functioning, which will take approximately 2 hours. The assessment will include an interview about their medical, psychiatric, and cognitive history. It will also include questionnaires about their symptoms and daily functioning as well as neuropsychological tests, which are paper-pencil tests that evaluate aspects of cognition such as memory, attention, and problem-solving skills. 2. Be randomly assigned (like the flip of a coin) to receive Goal-Focused Supportive Contact or Compensatory Cognitive Training. Both treatments will involve weekly groups with a mental health provider for approximately 2 hours per week for 8 weeks. Goal-Focused Treatment includes setting and achieving short-term and long-term goals for improving cognition and functioning. Compensatory Cognitive Training includes training in strategies to improve cognition and manage stress. 3. Complete a follow-up assessment of cognition, symptoms, and functioning 8 weeks after they begin treatment, as well as a brief interview about their experience in the group. These assessment sessions will take approximately 2 hours.

Novel invasive neurostimulation stimulation strategies through neurosurgical interventions are emerging as a promising therapeutical strategy for major depressive disorder. These have been applied mostly to the anterior cingulate cortex, but other limbic brain regions have shown promise as anatomical targets for new neurostimulation strategies. The researchers seek to study neural activity in limbic brain areas implicated in decision behavior and mood regulation to identify novel targets for treatment through electrical stimulation. To do this, the study team will record local field potentials (LFPs) from the orbitofrontal cortex, hippocampus and amygdala of epilepsy participants undergoing invasive monitoring (intracranial encephalography, iEEG) during choice behavior. Leveraging the high co-morbidity of depression and intractable epilepsy (33-50%), neural responses will be compared to reward across depression status to identify abnormal responses in depression. Finally, the researchers will use these as biomarkers to guide development of neurostimulation strategies for the treatment of depression.

Deep brain stimulation (DBS) is an effective treatment for people suffering from severe obsessive-compulsive disorder (OCD) whose symptoms have failed to improve after years and multiple methods of intervention. An effective DBS target for OCD is the anterior limb of the internal capsule (ALIC) brain region. On average 60% of all OCD patients have a clinically significant response to ALIC DBS. However, ALIC DBS may become even more effective with the ability to predict which specific ALIC connections in the brain need to be stimulated for each individual OCD patient. This study therefore investigates personalized stimulation to the ALIC that allows for precise modulation of brain circuits associated with individual OCD symptoms. The study aims to specify the ideal anatomical target for ALIC DBS for maximum therapeutic benefit in each patient.

There has been much interest in the potential role of social media (SM) use in driving a current mental health crisis among teens, with a dire need for evidence that goes beyond self-report. One important avenue is to understand the role of the brain in driving the effects of SM use on emotional health and vice versa. However, there is almost no research addressing these questions, largely due to a lack of tasks that can probe the neural correlates of modern SM use. The goal of this clinical trial is to develop and validate a new developmentally-appropriate and ecologically-valid functional magnetic resonance imaging (fMRI) and eyetracking task, the TeenBrainOnline (TBO) Task, that is more realistic and similar to modern SM platforms. Participants will be 50 teens (ages 13-17) with depressive symptoms who will complete the final version of TBO task during fMRI with eye-tracking, an older Chatroom Interact (CHAT-I) Task, daily surveys of SM use, and measures of depressive symptoms. Our goal is to show that the task works by: - Demonstrating that it activates expected regions of the brain and visual attention biases toward feedback cues. - Showing that brain and eyetracking (visual attention) activity on the task explain variability in depressive symptoms at baseline and three months later, and work better than similar indices from an older task. - Showing that brain and eyetracking (visual attention) activity on the task are associated with real-world measures of social media use collected during daily surveys. Specifically, The investigators expect that teens whose brain and eyetracking activity suggests they are more sensitive to feedback on SM will report a social evaluation orientation toward social media use in daily life, such as engaging a lot in social comparison, worrying about missing out, and caring about getting a lot of likes and comments. Participants will be asked to: - complete a 10-15 minute screening call to determine eligibility for the study - complete one 90 minute virtual study visit to complete questionnaires and prepare for the MRI visit (visit 1) - submit 24 photos to our study specific social media site - complete an (in person) MRI scan visit (~4 hours), which consists of 2 tasks where they will interact with peers (visit 2) - complete ~5 minute smartphone surveys 3 times a day for 16 days, asking about their daily experiences online and emotional reactions. - complete 2 online questionnaires asynchronously 3 months after their scan date

We will recruit 10 patients with OCD meeting established criteria for surgical evaluation. Following informed consent and baseline evaluations, each will be implanted with permanent DBS SenSight leads and the Medtronic Percept RC IPG, which has on-device neural recording capability and rechargeability. We will collect a broad array of neurobehavioral data across two environments with complementary advantages: the clinic and the home. The first 2 Aims test our mechanistic hypothesis by studying the pattern of VS neural activity in the controlled environment of the lab/clinic during two complementary paradigms: one based on a psychophysical behavioral task, the other based on ERP, a therapeutic behavioral intervention. The third aim tests this hypothesis in an ambulatory, naturalistic setting with chronic neural on-device recordings paired with time resolved behavioral measures. We will investigate a possible common neural basis underlying approach and avoidance across these 3 paradigms. Subjects will participate in research at 7 critical timepoints during routine clinic visits (Fig. 4): before implant, 1 day before DBS activation, immediately after DBS activation, 2 weeks, 3 months, 6 months, and 12 months after DBS initiation. At these timepoints, patients will complete clinical assessments, perform the Probabilistic Approach Avoidance Task (PAAT), and conduct exposure trials under the guidance of a psychologist. The clinic offers the most controlled environment and provides opportunities for collecting high temporal resolution behavior synchronized to local field potential (LFP) recordings. These data will allow us to identify the degree of overlap in the time-resolved neural activity driving individual decisions to approach potential rewards or avoid potential aversive stimuli (Aim 1), and resist performing compulsions in order to achieve relief after OCD symptoms are triggered (Aim 2). At home, our goal is to investigate patient trajectories along the approach-avoidance axis as OCD symptoms improve (Aim 3). We will leverage passive, on device recordings that occur in the background of everyday life activities and synchronize these neural recordings with data collected via wearables, ecological assessments, and video diaries. Capturing neural and behavioral data in the home environment is essential for understanding the neural and behavioral changes that occur over longer timescales than individual clinical visits. The neurobehavioral biomarkers generated by this dataset will provide trackable readouts of clinical status that could inform therapeutic decision-making and enable data driven intervention.

Post-traumatic stress disorder (PTSD) is a psychiatric disorder than may develop following a traumatic event including serious incidents, natural or human-caused disasters, violence, death of a loved one, receipt of traumatic news, or serious illness/hospitalization. While half of US adults experience trauma in their lifetime, most do not develop PTSD. However, those who do develop the disorder may have significant impairments and risk for functional dysfunction across multiple domains. While short term symptoms are the most common, some individuals develop chronic PTSD. These individuals may experience frightening and intrusive thoughts and memories of the event (flashbacks), have sleep disturbances, feel numb or detached, and be easily startled (hypervigilance). This trial is a double-blind placebo controlled study of cannabidiol (CBD) for symptoms of PTSD in adults using liquid structure Formulation (Nantheia ATL5). Participants complete three weeks of baseline data collection including assessments of activity and sleep. Intervention is Nantheia ATL5 or placebo. Dose is initiated at 400mg BID and maintained over 8 weeks. Standardized symptom profile measurements, clinician assessments, laboratory testing, collection of inflammatory biomarkers, and suicide screening is completed throughout. Age- and gender-matched healthy population participants are enrolled and complete baseline data collection only. All participants may complete optional functional magnetic resonance imaging (fMRI).

Suicide is the 10th leading cause of death for Americans of all ages and more people in the United States now die from suicide than die from car accidents. Although death by firearm remains the most common cause of suicide in the United States, an intentional overdose of substance usage such as prescription opioids accounts for over 5,000 suicides per year. In 2017, more than 70,000 drug overdose deaths occurred, making it the leading cause of injury-related death, and well over half (67.8%) involved opioids. The dramatic increase in opioid overdose raises concerns about their contribution to suicidal outcomes (e.g., suicidal behavior, ideation, and attempts). Abuse of prescription opioids is characterized by the persistence of opioid use despite negative consequences. The neurobiology of opioid abuse involves the mesolimbic dopamine systems as the main neural substrate for opioid reward, and altered dopamine release in this system plays a role in opioid abuse. Moreover, the cortico-striatal system, especially the orbitofrontal cortex (OFC), has been associated with the abuse of many substances, including opioids and alcohol. Structural brain alterations in frontal areas, particularly the OFC, may cause executive control dysfunctions of mood which are highly associated with suicidal ideation. Recent preclinical work has shown that higher input from the OFC to the dorsal striatum (dSTR) is associated with compulsive reward-seeking behavior despite negative effects (e.g., punishment). In this study, the investigators propose that OFC/dSTR connectivity may be one neural differentiator that distinguishes between those who become compulsive users after initial opioid use and those that do not. Moreover, suicidal patients among those who become compulsive users may have higher OFC/dSTR connectivity compared to non-suicidal patients.
