18 Clinical Trials for Various Conditions
The purpose of this study is to design and test the safety and feasibility of virtual reality technologies and experiences of egocentric avatar embodiment in the application of physical and cognitive behavior therapy in functional neurological symptom/conversion disorder. Investigators hypothesize that patients will safely use and accept this modality of treatment and will show evidence of a decrease in symptom frequency.
Functional Neurological Disorder (FND/ Conversion Disorder) is a highly prevalent and disabling neuropsychiatric condition. Motor FND symptoms include Nonepileptic Seizures, Functional Movement Disorders and Functional Weakness. Clinical research across these motor FND subtypes, including research studies from the candidate's laboratory, suggest that these populations share many clinical and phenotypic similarities that warrant increased research integration. Furthermore, despite the prevalence of motor FND, little is known about the underlying pathophysiology of this condition, which is a prerequisite for the development of biologically informed prognostic and treatment response biomarkers. Across 3 published neurobiologically focused articles, the candidate proposed a framework through which to conceptualize motor FND. It is suggested that motor FND develops in the context of structural and functional alterations in neurocircuits mediating emotion awareness/expression, bodily awareness, viscerosomatic processing and behavioral regulation. The overall goal of this project is to comprehensively investigate structural and functional magnetic resonance imaging (MRI) biomarkers of prognosis across motor FND. Multimodal structural and functional MRI techniques (including voxel-based morphometry, cortical thickness, resting-state functional connectivity and diffusion tensor imaging tractography) will be used to systemically probe brain-prognosis relationships. Novel aspects of this proposal include the study of the full spectrum of motor FND, consistent with a trans-diagnostic approach.
The investigators propose that patients who receive targeted pharmacotherapy (sertraline) or focused psychotherapy (cognitive behavioral therapy-informed psychotherapy (CBT-ip) for NES) or combined treatment (CBT-ip + sertraline) will report fewer nonepileptic seizures (NES) compared to patients who receive community care / treatment as usual (TAU). The purpose of this study is to provide pilot testing and data to inform the future multicenter randomized controlled trial based on the hypothesis.
This multi-site study will examine patients with epilepsy (ES) following head injury \[i.e., posttraumatic epilepsy (PTE)\] and posttraumatic psychogenic Non-epileptic seizures (PNES) and will compare them to patients with traumatic brain injury (TBI) who do not have seizures using functional neuroimaging.
The investigators propose that treatment of the comorbid disorders (depression, anxiety, and impulsivity) with sertraline in patients with lone psychogenic nonepileptic seizures (NES), will result in a decreased number of NES. The purpose of this study is to provide pilot testing and data to inform the future randomized controlled trial based on the hypothesis.
The goal of this pilot randomized clinical trial is to learn if Neurobehavioral Therapy (NBT) works to treat motor functional neurological disorder (mFND) (also referred to as functional motor disorder). The main questions it aims to answer are: * Does NBT lower mFND symptoms? * Does NBT lower common co-occurring symptoms and improve functioning? Researchers will compare NBT to standard medical care (SMC). Participants will be randomized to receive either: * 12 weekly sessions of NBT, along with their SMC, * or continue receiving their SMC as provided by their treating clinicians. * all participants. regardless of group assignment, will complete a total of five in-clinic visits at the following time points: Baseline, 6 weeks, 12 weeks, 8 Months and 12 Months for self-report surveys to assess functional status, quality of life and mFND symptoms.
Background: Functional movement disorders (FMD) involve involuntary movements that are not due to a recognized neurological or medical cause. FMD can cause major disability. Researchers want to learn more to create better treatments for FMD. Objective: To test whether non-invasive brain stimulation using transcranial magnetic stimulation (TMS) improves FMD symptoms. Eligibility: People between the ages of 18 and 80 who have been diagnosed with FMD by a neurologist. Design: Participants will be randomly assigned to one of two groups. One group is an active brain stimulation group and the other is a sham brain stimulation group. Participants will have a baseline visit. This will include: Neurological exam Questionnaires Urine test Brain MRI: Participants will lie in a machine that takes pictures of the body. They will be asked to respond to images on a screen while in the scanner. Within 2 weeks of the baseline visit, participants will begin 5 daily sessions of TMS. The active group will have stimulation delivered to the brain via a coil. In the sham group, a dummy coil will be used that will not deliver stimulation. A total of three 3-minute cycles will be done in one visit. There will be 20-minute breaks between the cycles. Participants will have visits 1 month, 2 months, and 6 months after their last day of TMS. Their FMD symptoms will be evaluated. They will complete health questionnaires. These visits can be in person or virtual.
Functional Neurological Disorder (FND/ Conversion Disorder) is a highly prevalent and disabling neuropsychiatric condition. Motor FND symptoms include Functional Movement Disorders (FMD) and Functional Weakness and Psychogenic Nonepileptic Seizures (PNES).Though patients with FND present with a wide variety of symptoms, FMD, PNES, and functional weakness may be viewed as overlapping conditions lying along a phenotypic spectrum for a single disorder. Patients with FND frequently present with psychiatric symptoms, including depression, anxiety, Borderline Personality Disorder, and Post-Traumatic Stress Disorder, alongside their physical symptoms. To treat these symptoms, patients with FND are frequently enrolled in physical therapy and cognitive behavioral therapy, which are considered usual care for FND at our center. Developing a further understanding of treatment outcome, including biomarkers of clinical improvement and psychometric factors associated with treatment response, could inform future interventions and better tailor treatments to patients with specific FND symptom profiles. We hypothesize that treatment response will be associated with structural and functional alterations in salience network regions and that more adaptive neuropsychiatric profiles at baseline will predict a positive treatment outcome.
This study is part of a series of studies that will explore how the mind and the brain work to cause episodes of uncontrollable shaking in people who have no known underlying brain or medical disorder. The study is conducted at NIH and at the Brown University Rhode Island Hospital. Healthy volunteers and people with functional movement disorders (FMD) or non-epileptic seizures (NES) who are 18 years of age or older may be eligible for this study. Patients with NES have 3 teaspoons of blood drawn. The blood is tested for two genes that are normally found in healthy individuals to see if they are found more frequently in patients with uncontrolled shaking. Patients with FMD have blood drawn for testing and also undergo functional magnetic resonance imaging (fMRI) to look at how the brain functions while the subject performs a specific task. MRI uses a strong magnetic field and radio waves to obtain images of body organs and tissues. During the scan, the subject lies on a table that can slide in and out of the scanner, a metal cylinder. The scan lasts about 60 to 90 minutes, during which the subject may be asked to lie still for up to 10 minutes at a time and to perform tasks, such as identifying the gender of faces shown on a screen. Healthy volunteers may have blood drawn for genetic testing or fMRI or both.
This study will explore how the mind and the brain work to cause movement symptoms or seizures in people who do not have a recognized neurological or medical disorder. The study includes a check for psychiatric disorders, symptoms and their severity; psychiatric and personality questionnaires; and neuropsychological testing. Normal, healthy volunteers, people who have movement symptoms not due to a brain or medical disorder and people who have seizures not due to epilepsy may be eligible for this study. All candidates must be 18 years of age or older. All participants have a medical history, physical examination and psychological evaluation, including completion of questionnaires. People with movement symptoms or seizures have a symptoms evaluation. Some participants also undergo neuropsychological testing, including questionnaires, pen-and-paper or computerized tests, and motor tasks.
This study aims to evaluate the neurobiological basis of traumatic dissociation in a cross-diagnostic sample of women who have histories of childhood abuse and neglect.
This is a double blind active placebo controlled clinical trial for individuals within an inpatient setting with moderate to severe depression. The purpose of this study is to assess if nebulized ketamine can reduce depressive symptoms.
Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation.
This is a randomized controlled trial (RCT) on the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) in the treatment of Depersonalization Disorder (DPD). TMS applies a magnetic field to the brain for a brief period of time. TMS is a procedure that involves 30 minute-long daily sessions every weekday for a series of weeks. The investigators are testing whether TMS can treat Depersonalization Disorder (DPD).
The purpose of this study is to evaluate the clinical efficacy of transcranial magnetic stimulation in the treatment of Depersonalization Disorder (DPD).
Co-occurring post-traumatic stress disorder (PTSD) and major depressive disorder (MDD) is the most common response to trauma; it is associated with poor clinical outcomes and substantial human disability. Veterans with both PTSD and MDD (PTSD+MDD) have been shown to be at much greater suicidal risk than individuals with only one of these disorders. Ketamine given as repeated infusions has been shown to be effective in rapidly reducing PTSD and MDD symptoms in treatment resistant PTSD+MDD individuals. However, knowledge about the mechanisms underlying comorbid PTSD and MDD remain limited. The purpose of this study is to use repeated ketamine infusions as a probe to validate a model of PTSD+MDD that focuses on neuroanatomy and executive functioning.
The relationship between depression and trauma is well established. Co-occuring depression and post-traumatic stress disorder (PTSD) are associated with more severe symptoms and lower levels of functioning. Veterans with both depression and PTSD have been shown to be at much higher risk of suicide than individuals with only one of these disorders. Ketamine has been shown to have rapid antidepressant effects and also therapeutic action over PTSD symptoms. The purpose of this study is to see whether ketamine, when given as repeated infusions, can produce quick and sustained improvement in depression and PTSD symptoms for individuals who have not had their symptoms effectively treated by current treatments.
The purpose of this study is to assess the effects of simultaneous administration of oral aspirin and oral ketamine as a therapeutic for those with Treatment Resistant Depression.
