Objective: To screen and create a list of adult volunteers in good health for participation in research studies conducted at the National Institutes of Health (NIH) in Bethesda, Maryland. Develop a normative set of structural and functional brain MRI scans that are linked to healthy research volunteer characteristics. Maximize scientific impact of data from volunteers by broadly sharing with other researchers. Study Population: Adult males and females in general good health who are 18 years of age and older. Design: Adult individuals who are interested in participating in NIMH IRP clinical studies as a healthy research volunteer can directly visit or be directed to visit the study website where they will first consent electronically and then complete a set of online self-report measures. Items may include: demographic information, mental health symptoms, disability status, substance use patterns, handedness and clinical/family history. Individuals who are flagged based on predetermined responses to survey items will be further screened by a member of the study clinical team. If found to be ineligible for the study because of a clinically significant or unstable medical or mental health condition, these individuals will be referred back to the community and/or given information about NIMH clinical studies for which they may be eligible. Respondents with no flags or who pass through additional screening will be scheduled for an in-person assessment. During the outpatient appointment and after in-person informed consent, participants will receive a brief clinical interview to screen for current medical and mental conditions, and risk for self-harm. They will complete assessments of psychological, emotional, physiologic, biological and cognitive functioning. Participants will undergo a physical exam and be asked to provide blood and urine samples for routine clinical labs. Participants can separately consent for an optional baseline brain magnetic resonance imaging (MRI) scan and an optional magnetoencephalography (MEG) exam. All consent forms will explicitly inform participants that if enrolled in the study, their de-identified data will be broadly and publicly shared through NIH-approved data repositories. Participants in this recruitment and characterization study will then be placed on a list of healthy research volunteers from which other NIMH IRP studies may recruit according to the inclusion and exclusion criteria in their respective IRB-approved protocols. Outcome Measures: Outcome measures may include demographic data, mental and medical history and symptoms, results of psychological, emotional, physiologic, biological, and cognitive testing, physical exam and MRI findings....

Background: - Deep brain stimulation (DBS) is an approved surgery for certain movement disorders, like Parkinson's disease, that do not respond well to other treatments. DBS uses a battery-powered device called a neurostimulator (like a pacemaker) that is placed under the skin in the chest. It is used to stimulate the areas of the brain that affect movement. Stimulating these areas helps to block the nerve signals that cause abnormal movements. Researchers also want to record the brain function of people with movement disorders during the surgery. Objectives: - To study how DBS surgery affects Parkinson s disease, dystonia, and tremor. - To obtain information on brain and nerve cell function during DBS surgery. Eligibility: - People at least 18 years of age who have movement disorders, like Parkinson's disease, essential tremor, and dystonia. Design: - Researchers will screen patients with physical and neurological exams to decide whether they can have the surgery. Patients will also have a medical history, blood tests, imaging studies, and other tests. Before the surgery, participants will practice movement and memory tests. - During surgery, the stimulator will be placed to provide the right amount of stimulation for the brain. Patients will perform the movement and memory tests that they practiced earlier. - After surgery, participants will recover in the hospital. They will have a followup visit within 4 weeks to turn on and adjust the stimulator. The stimulator has to be programmed and adjusted over weeks to months to find the best settings. - Participants will return for followup visits at 1, 2, and 3 months after surgery. Researchers will test their movement, memory, and general quality of life. Each visit will last about 2 hours.

People with hereditary hemorrhagic telangiectasia (HHT) often experience frequent and severe nosebleeds that can disrupt daily life and lead to anemia, medical procedures, and reduced quality of life. This study is testing a new nasal ointment called TOR-582, which contains sirolimus, to determine whether it can be used safely when applied inside the nose. Adults with HHT and frequent nosebleeds will be invited to participate. Participants will first complete one week of observation without treatment, followed by up to 12 weeks of applying the study ointment inside each nostril twice daily. Different participants will receive different strengths of the ointment so researchers can identify the safest dose. During the study, participants will attend study visits, complete questionnaires about their nosebleeds and quality of life, keep a daily nosebleed diary, undergo nasal examinations, and have blood tests to monitor safety and medication levels. The information gained from this study will help determine whether this topical treatment can be safely studied further and will support the development of a new, less invasive option for managing nosebleeds in people with HHT.

Female life stages including premenopausal, perimenopausal, postmenopausal, are characterized by changing concentrations and patterns of hormones. The premenopause stage represents the reproductive years with normal menstrual cycles lasting between 21-35 days. The perimenopause stage is the beginning of the menopause transition and can last up to 10 years. During this transition, menstrual cycles become longer and irregular in length (7 days or longer). After 12 consecutive months with no period, the transition is complete into the postmenopause stage. Hormones that change across the lifespan are known to influence systems that regulate thirst, fluid balance, and sodium balance. Yet, fluid balance across life stages remains poorly understood, with no direct comparisons across all three life stages. The purpose of this study is to evaluate the effect of female life stage on rehydration with water and electrolyte solution after overnight fast and fluid restriction

The primary objective is to establish a Cleveland Clinic-led registry designed to integrate continuous physiological data from consumer wearables, captured by the HeartBit app and a Case Western Reserve University (CWRU)-based platform, with clinical data from patients' individual Electronic Health Record (EHR). This proposal is for understanding the use of personal wearable devices (such as: Fitbit, and Apple Watch) to gather physiological data (such as: heart-rate, steps taken, sleep cycles, and calories expended) and correlate those data with self-reported health status. The research team intends to collect all of the data generated by the participant's personal wearable devices and to perform an integrated analysis of the physiological data generated by the wearable devices. The investigators specifically aim to uncover patterns from the data that they can evolve models from. The investigators' goal is to better predict and diagnose the adverse effects associated with daily lifestyle, including cardiovascular risk, musculoskeletal, metabolic risks, stress, and sleep disturbances. These data may be used to better understand the daily habits and lifestyle choices to possibly predict a person's health and disease risk to provide a more comprehensive diagnosis with early recognition and prevention. As wearable devices become more accurate and cheaper to purchase for the general public, integrative analysis of wearable data from multiple devices may lead to models that can be used by clinicians and basic scientists to make inferences about the daily lifestyle and its effects on health and disease.
