Neurocysticercosis is a brain disease due to the larval stage of the pork tapeworm (Taenia solium). The most common symptoms patient experience from infection inside the substance of the brain (parenchymal disease) are seizures and headaches. When the infection is either inside the fluid pockets inside the brain (ventricular disease) or in the space around the brain (subarachnoid disease) patients can have chronic headaches, relapsing aseptic meningitis, hydrocephalus, stroke, and may require neurosurgical intervention. The purpose of this study is to treat patients with anthelmintic therapy (praziquantel and/or albendazole) and anti-inflammatories in alignment with currently accepted best practices and guidelines, depending on the neurocysticercosis subtype. The purpose of the study is to better understand and characterize clinical, biologic, and management factors during treatment that influence long term outcomes. In order to understand this further we collect patient clinical information, patient survey responses, blood, urine samples, and additional cerebral spinal fluid if already being collected for clinical care.

Background: About 180,000 of the people in US prisons are over 55 years old. Aging people often cannot make medical decisions on their own. People who cannot make their own decisions must rely on a "surrogate." A surrogate is someone who helps the person's doctor make decisions for them. Researchers want to conduct a survey to ask people in prison who they would like to be their surrogates. But first, they need to find out if their survey questions are clear and easy to understand. Objective: To get imprisoned people's feedback on survey questions about surrogate decision making. Eligibility: People currently imprisoned in a US facility with access to Edovo. They must be able to read and write in English. Design: Participants will answer 26 survey questions. The questions will be on the Edovo Learn software platform. After each question, they will be asked: "Was this question clear? If not, please explain in the box below what you found unclear. Also, if you have any suggestions for how we might make the question clearer, please include them." Participants will be asked to imagine themselves in a situation where they cannot make their own medical decisions. They may skip questions or stop the survey if they want. No information that identifies them will be collected. The survey will take about 15 minutes.

Background: - The third molars (wisdom teeth) normally grow in during late adolescence or early adulthood. Many people need or choose to have these teeth removed with oral surgery. Normally, the removed teeth and tissue are thrown away as medical waste. However, oral health researchers want to collect the teeth and tissue for research. They also want to encourage dentists at the National Institutes of Health to improve their skills in oral surgery. This study will collect the teeth and tissue of people who need to have oral surgery to remove their wisdom teeth. Objectives: - To provide continued dental skills training for dentists at the National Institutes of Health. - To collect teeth and tissue samples following wisdom tooth removal surgery. Eligibility: - Individuals between 16 and 50 who need to have their wisdom teeth removed. Design: - This study will involve a minimum of three visits. There will be a screening visit, a surgery visit, and at least one follow-up visit. - Participants will be screened with a physical exam and medical history. A full dental exam with x-rays will be given to evaluate the need for surgery. - At the second visit, participants will have oral surgery to remove their wisdom teeth. The teeth and tissue removed during the surgery will be collected for study. - Participants will receive drugs to control the pain after surgery. They will also be able to contact a dentist if there are any problems. - Between 7 and 21 days after surgery, participants will have a followup visit to check the healing. If they are having no problems, this will be the last visit. If there are any postsurgery issues, they will be scheduled for additional visits as needed.

Background: - Progressive multifocal leukoencephalopathy (PML) is a severe viral infection of the brain. It is caused by JC virus. Many people have this virus in their bodies all their life, but it is usually kept in check by their immune system. If the immune system does not work right because of a disease or medication, the virus becomes active and can damage cells in the brain. Not much is known about PML or how it affects the immune system. Researchers want to study people with PML to better understand the natural history of the disease. Objectives: - To study the natural history of PML. Eligibility: - Individuals at least 2 years of age who have PML. Design: - Participants will be screened with a physical exam, medical history, and imaging studies. - Participants will have several visits to the National Institutes of Health Clinical Center. There will be an initial visit, monthly visits for the next 6 months, a 12-month visit, and possible visits afterward. - At the initial visit, participants will give blood, urine, and spinal fluid samples. They will also have neurological tests and imaging studies of the brain. - For the next five visits, participants will give blood and urine samples. They will also have neurological tests and imaging studies of the brain. - The 6-month and 12-month visits will repeat the tests from the initial visit. - Other optional procedures include bone marrow samples and skin biopsies. Additional blood tests and imaging studies may be performed. - Treatment will not be provided as part of this study.

Background: Allergic and inflammatory conditions have been increasing over the years. Many factors may play a role in this. Every day, people are exposed to pollution and chemicals in our foods, clothing, and all of the cleaning, hygiene, and other products we use. Studies have suggested there may be links between these environmental exposures and allergic and inflammatory illnesses. Researchers want to know more about how these exposures affect our health. Objective: To learn how everyday exposure to common substances affects people's health. Eligibility: Healthy people aged 18 to 80 years. Design: Participants will have 2 stays in the hospital. Each stay will last 7 days, and the stays will be spaced 4 to 6 weeks apart. During both stays, participants will remain confined to their room. They will eat only food from the menu, and they will use only provided products for personal care. (They may bring their own electronic devices, such as their phone and computer.) One stay will be in a pure room. Participants will breathe filtered air, eat unprocessed foods, and use personal care products with fewer chemicals. One stay will be in a room that allows exposure to common environmental chemicals. Some participants will be limited to only 1 type of exposure: chemicals thought to affect only skin, gut, or respiratory health. Some participants will be exposed to all 3 types. Participants will undergo testing. Blood, skin cell, urine, mouth swabs, and stool samples will be taken. They will have lung tests, smell tests, and tests that measure the health of their skin. These tests will be repeated in outpatient visits 2 weeks after each hospital stay....

Study Purpose Functional Electrical Stimulation (FES) enhances motor recovery by increasing the functional range of motion to significantly improve muscle force deficits following an acquired brain injury. While FES has shown promise in improving muscular activation, its role in facilitating fine motor skills like handwriting in the acquired brain injury population needs further investigation. The project will incorporate motion capture (mo-cap) analysis technology, which will capture participants' detailed movement patterns during handwriting tasks and provide multi-baseline pre-analysis/post-analysis of motor planning and execution for precise tracking of manual dexterity improvements by quantifying changes in fine motor control, speed, and accuracy. The study seeks to provide comprehensive evidence of FES's effectiveness in hand remediation with combined assistive technology with functional-based activity to enhance motor function and improve acquired brain injury survivors' quality of life by enabling better outcomes in daily tasks requiring fine motor skills. Functional electrical stimulation improves reaching movement in the shoulder and elbow muscles of stroke patients:

This randomized controlled trial will compare two upper-extremity restraint techniques in patients undergoing elective cesarean delivery under neuraxial anesthesia. Participants will be randomly assigned to either standard forearm restraint placement or wrist-level gripping restraint placement. The study will evaluate whether the position of the restraint affects maternal anxiety during and after cesarean delivery. Anxiety will be measured at several perioperative time points using the State-Trait Anxiety Inventory (STAI-6). Secondary outcomes include pain, patient satisfaction, physiological measures such as heart rate and blood pressure, postpartum distress and mood, and restraint-related safety events. The study aims to determine whether wrist-level gripping restraints may reduce anxiety and improve the patient experience compared with standard forearm restraints.

This study investigates whether transcranial electrical stimulation (tES) delivered during structured reading instruction affects reading proficiency in children with developmental dyslexia and related reading disabilities. Children aged 7 to 17 who have been identified as having dyslexia or reading difficulties are randomly assigned in equal numbers to receive either active stimulation or sham (placebo) stimulation while completing structured reading instruction. Participants wear a non-invasive transcranial electrical stimulation headset that delivers a low-level electrical current through electrodes resting on the scalp. Sessions typically last 20 to 30 minutes and may take place at home or in person at a participating site. A trained adult is present and supervising for every session. Reading proficiency is measured with standardized assessments before and after the intervention period. A follow-up assessment may be conducted up to 12 months after the intervention ends. The device used in this study is investigational and has not been approved or cleared by the U.S. Food and Drug Administration.
