Previous clinical studies revealed that the newly developed biophoton therapy has been safe and effective in treating patients with Alzheimer's disease, dementia, stroke, traumatic brain injury, or Parkinson's disease. The current study is to confirm the previous clinical observation by conducting as a randomized, triple-blinded, placebo-controlled prospective intervention clinical research. About 80 patients with brain disorder (Alzheimer's disease, dementia, stroke, traumatic brain injury, Parkinson's disease) will participate in the intervention clinical study at the Tesla MedBed Center located in Butler, PA.
This phase II trial compares the effect of single fraction stereotactic radiosurgery to fractionated stereotactic radiosurgery for the treatment of patients with cancer that has spread to the brain (metastatic brain disease). Stereotactic radiosurgery (SRS) is a form of radiation therapy that focuses high-power energy on a small area of the body. This trial is being done to determine if single (one) fraction stereotactic radiosurgery is better than fractionated stereotactic radiosurgery or vice versa in controlling tumor and side effects in patients with tumors that have spread to the brain.
Background: About 5 million adults in the U.S. have Alzheimer s disease or another adult-onset neurodegenerative disorder. Many studies have found that inflammation in the brain contributes to these diseases. Researchers want to find a better way to measure this inflammation. Objective: To learn whether COX-1 and/or COX-2 is elevated in the brains of individuals with neurodegenerative brain disease compared to healthy volunteers. Eligibility: Adults age 18 years and older in good general health who have an adult-onset neurodegenerative dementia, such as AD, FTD, corticobasal syndrome, Huntington s disease, or MCI, ALS and healthy adult volunteers enrolled in protocols 01-M-0254 or 17-M-0181. Design: Participants will be screened with medical history, physical exam with vital signs, and lab tests. They will have a neuropsychological testing. Their heart function will be measured. Participants will have a magnetic resonance imaging (MRI) scan. The MRI scanner is a metal tube surrounded by a strong magnetic field. Participants will lie on a table that slides in and out of the tube. The machine makes noise. Participants will get earplugs. Participants will have 2 PET scans. They will be injected with the study drugs through an intravenous catheter placed in an arm vein. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. A plastic mask will be molded to their head to keep them from moving. A thin plastic tube will be put into an artery at the wrist or elbow crease area. This will be used to draw blood during the scan. Participants will have 2-5 study visits. Participation lasts 1 week to 4 months, depending on scheduling.
This study is being done to see if adding GLIADEL to the site where the tumor was removed works as well as just having the tumor removed with radiation treatment done within six weeks after the surgery to keep the cancer from coming back.
The objective is to understand how amygdala activation affects other medial temporal lobe structures to prioritize long-term memories. The project is relevant to disorders of memory and to disorders involving affect and memory, including traumatic brain injury and post-traumatic stress disorder.
The primary goal of this project is to study the feasibility of a prototype brain-dedicated PET insert for an MR scanner for simultaneous acquisition of PET/MR images of metabolism and perfusion in Covid-19 negative and positive/once positive subjects. This study serves as a pilot study for establishing an imaging protocol for combined PET and MR derived functional information as well as MRI acquired anatomical information.
The primary goal of this project is to study the feasibility of a brain-dedicated PET insert for an MR scanner for simultaneous acquisition of PET/MR images of human brains. The study will also allow us to compare the imaging performance of the investigator's brain-dedicated PET insert against a commercial whole-body permanently integrated PET/MRI system using a common radiopharmaceutical.
Background: - Inflammation is how the body reacts to infection or injury. Infections or inflammation in the brain and nerves can be serious. There aren t always good tests to detect this. Researchers want to learn more about how diseases affect the brain and nerves to develop better tests and treatments. Objective: - To learn more about how inflammation and infections hurt the brain and nervous system. Eligibility: - People at least 2 years old with a diagnosis or suspected diagnosis of nervous system infection or inflammation. Design: * For some participants, a clinician outside of NIH will collect blood, tissue, and other samples. These will be sent to NIH and analyzed. * Other participants will have several visits to NIH. Children may not have all these tests. * Participants will have: * Medical history. * Physical and neurological exam. * Blood and urine samples collected. * Saliva collected. They will chew on a piece of sterile cotton for one minute. * Magnetic resonance imaging (MRI) scan. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. Participants will get a contrast agent through an intravenous (IV) catheter during the MRI. A needle will be used to guide a thin plastic tube (catheter) into an arm vein. * Lumbar puncture. Skin will be numbed and a needle will be inserted into the space between the bones in the back. Fluid will be removed. * Some participants may have optional study procedures. These may include eye tests, memory and thinking testing, tests with electrodes on the head, or skin biopsy.
Dr. Elliott Sherr and his collaborators at University of California, San Francisco (UCSF) are studying the genetic causes of disorders of cognition and epilepsy, in particular disorders of brain development that affect the corpus callosum, such as Aicardi syndrome, as well as two additional brain malformations, polymicrogyria and Dandy-Walker malformation. The goal of the investigators' research is to use a better understanding of the underlying genetic causes as a foundation to develop better treatments for these groups of patients.
Urea cycle disorders (UCD) are a group of rare inherited metabolism disorders. Infants and children with UCD commonly experience episodes of vomiting, lethargy, and coma. The purpose of this study is to perform a long-term analysis of a large group of individuals with various UCDs. The study will focus on the natural history, disease progression, treatment, and outcome of individuals with UCD.
