Filter by:It has been suggested that N-acetylcysteine exerts neuroprotective effects by regulating neurotransmitters and cell signaling pathways. We hypothesize that oral N-acetylcysteine augmentation will help reduce symptoms in patients with posttraumatic stress disorder as well as improve cognitive functions. We also expect that the N-acetylcysteine augmentation will induce change in structural, functional, and neurochemical aspects of the brain. In this study, we plan to conduct a randomized, double-blind, placebo-controlled augmentation study with N-acetylcysteine in addition to escitalopram. We will assess the efficacy and safety of the N-acetylcysteine augmentation.
The purpose of this study is to determine whether deep brain stimulation of the basolateral nucleus (BLn) of the amygdala, on both sides of the brain, can safely reduce symptoms of post-traumatic stress disorder (PTSD) in combat veterans whose condition has not improved despite extensive treatment with currently available medication and psychotherapy interventions.
The purpose of this study is to determine the effects of triptans and doxycycline on neuroinflammatory markers in acute migraine.
Ketamine infusions resulted in an acute reduction in global depression scores and in severity of suicidal ideation. Scopolamine infusions produced also a significant improvement in depression that was sustained over time. We therefore plan to investigate the feasibility and efficacy of open-label repeated intravenous administration of ketamine and scopolamine combined in this population of severely depressed, treatment-resistant patients. The results from this study could lead to the development of new strategies for the treatment of patients with TRD.
The pilot study will evaluate whether electronic-Measurement Based Care (e-MBC) using the UT Southwestern MyChart personal health record is feasible, associated with patient and health care team satisfaction, and improves treatment outcomes compared to a standard treatment model. The project will be conducted in the Simmons Cancer Center Clinic at the University of Texas Southwestern Medical Center, Dallas as a collaborative effort between the Departments of Psychiatry, Oncology, and Family and Community Medicine. The primary patient population will include adults with significant depression and/or starting an antidepressant treatment and/or experiencing a treatment change. The study will compare two groups, an e-MBC group and an office-based standard care MBC group. Study staff will explain the study to the patients, specifically explaining that study participants will receive either office-based MBC or e-MBC. Eligible participants must be willing to receive either form of treatment monitoring. Participating patients will be randomly assigned to receive either e-MBC or office-based MBC. In the e-MBC group once a month the study nurse will send a prompt from the participating patients treating physician requesting the patient to use the MyChart system to fill-out the MBC scales. Beyond these monthly assessments, patients will be encouraged to utilize the MyChart MBC assessments (e-MBC) at any time to communicate with their physician. Patients experiencing difficulties using the e-MBC system will be given additional instruction by the study nurse. Patients and physicians will be trained in the use of the eMBC system. In the office-based MBC group the study nurse will schedule monthly treatment visits and request the patient call as needed to report symptoms. The evaluation period will be 6 months.
Objective of this study are: 1) To determine if medication help extreme preterm infants to tolerate feeding better by reaching full feeding earlier.2) Out of two medication; which one is better for efficacy 1) Erythromycin 2) Metoclopramide. Infants who meet inclusion criteria would be entered to study after parental consent. Infant would be blinded to care givers. Infants will be randomized to receive one of three medication for 7-14 days. If infants fail on one medication they will be allowed to crossover to other medication. Infant would be allowed to treat like other infants. Blindness can be broken if deem necessary by attending neonatologist.
Background: - Antidepressants help many people with depression, however, some do not seem to benefit as much. Currently, it is not possible to determine who will improve with certain antidepressants. Studies have shown that genes may influence whether an antidepressant works for an individual. Other studies have shown that depressed people tend to have lower levels of a chemical called glutamate in parts of their brain, and that glutamate levels increase after recovering from depression. Researchers want to study the antidepressant citalopram (Celexa) to see how it affects glutamate levels in the brain. They also want to study how a person s genes affect their response to this treatment. Objectives: - To see whether glutamate levels and certain genes affect how a person responds to a particular antidepressant medication. Eligibility: - Individuals between 25 and 55 years of age who have been diagnosed with major depression (without psychotic features). Participants may not have tried more than three antidepressant treatments. Design: - Participants will be screened with a physical exam and medical history. They will answer questions about mood and current feelings of depression, as well as family history of depression. Blood and urine samples will be collected. - This study will have two phases. The first phase may last up to 7 weeks depending on current antidepressant use and involves one to seven outpatient visits. The second phase lasts 8 weeks and involves five outpatient visits, one every 2 weeks. - In the first phase, participants will stop taking their current antidepressant medications for at least 2 weeks before the next phase of the study. Participants who are on fluoxetine (Prozac) will need to be off it for 6 weeks. - At the end of this phase, participants will have brain imaging studies to look at brain function and chemistry. - In the second phase, participants will take citalopram at the standard dose. They will answer questions about mood and response to the medication. They will also provide blood and saliva samples for tests. - At the end of this phase, participants will have brain imaging studies to look at brain function and chemistry.
The investigators will assess Li-induced gray matter volume changes with regard to the endophenotype of GSK3beta polymorphism. The changes of gray matter are supposed to be more attributable to neurotrophic and neuroprotective characteristics of Li, which were closely related to the inhibition of apoptotic activity of GSK3beta.
The purpose of this study is to determine the Finger Blood Glucose (sugar) when dexamethasone is added to a local anesthetic for a shoulder nerve block procedure. The investigators hypothesize that there is no increase in plasma glucose when 8 mg of dexamethasone is used as an adjuvant with local anesthetic to interscalene regional anesthesia. By performing finger stick blood glucose measures pre/peri and post operatively the investigators will be able to determine if any such increase exists.
Objective The objective of this pilot study is to characterize the abnormal neuronal firing patterns of basal ganglia neurons and those in the premotor cortex in patients with treatment-resistant movement disorders undergoing deep brain stimulation (DBS) surgery. Study population Fifteen adult patients with treatment-resistant movement disorders who are undergoing deep brain stimulation surgery at Suburban Hospital, Bethesda, Maryland, will be studied. Design This is a physiology study of treatment-resistant movement disorder patients who have been scheduled for implantation of a deep brain stimulation device into the Nucleus accumbens. Prior to surgery, patients will learn a rewarded visual-motor task and undergo magnetoencephalography. The task will be repeated during DBS surgery, with collection of information on electrical activity including single neuronal unit and local field potentials. The task and MEG will be repeated 3-4 months after surgery. The collected data will be analyzed for coherence patterns during rest and rewarded movements. Outcome measures We plan to characterize and quantify the oscillatory activity present in motor circuits of treatment-resistant movement disorder patients during rewarded visually guided movements. We hypothesize that during visually guided movements, neuronal coherence will be significantly increased relative to resting periods. Thus, by better understanding the alteration in oscillatory patterns in these patients, we hope to develop better DBS stimulation paradigms in order to better treat this disease in the future.
