Background: Most people who are referred to the EMG (Electromyography) Section of the NIH are enrolled into specific active studies. This allows researchers to learn about a range of rare neuromuscular disorders. But study criteria may not give researchers the chance to evaluate a single person or study a common symptom. Therefore, researchers want to assess people with neuromuscular disorders who are not currently enrolled in any NIH studies. They will perform tests on these individuals in the EMG Lab. Then they will create a repository of data that may be used for future research. This will help them learn more about these disorders. Objective: To retain data that is collected as part of participant visits to the NIH. Eligibility: People aged 18 and older who will be visiting the NIH for evaluation of their neuromuscular disorder. Design: Participants will be screened with a medical record review. Participants will have a physical exam. They will be evaluated for their neuromuscular disorder. They may have tests to learn more about how their nerves and muscles work that are called nerve conduction and EMG studies. Their muscles and nerves may be assessed with an ultrasound. Their ability to sweat may be measured. Their heart rate and blood pressure may be taken. Changes to their breathing or changes in their body position may be measured. Participant data will be given a unique numerical identifier that can be used if the data is shared. Data will be stored on a server and in a database. Participants will have 1-2 visits. Each visit will last less than 4 hours. They may be contacted for a follow-up visit.

Hermansky-Pudlak Syndrome (HPS) is an inherited disease which results in decreased pigmentation (oculocutaneous albinism), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin). The disease can cause poor functioning of the lungs, intestine, kidneys, or heart. The major complication of the disease is pulmonary fibrosis and typically causes death in patients ages 40 - 50 years old. The disorder is common in Puerto Rico, where many of the clinical research studies on the disease have been conducted. Neither the full extent of the disease nor the basic cause of the disease is known. There is no known treatment for HPS. The purpose of this study is to perform research into the medical complications of HPS and begin to understand what causes these complications. Researchers will clinically evaluate patients with HPS of all ethnic backgrounds. They will obtain cells, blood components (plasma), and urine for future studies. Genetic tests (mutation analysis) to detect HPS-causing genes will also be conducted.<TAB>

The rationale for this study is to observe the impact of a consumer-grade commercially available product called Milamend Hormone Balance on quality of life and hormonal health in women with self-reported symptoms associated with Polycystic Ovarian Syndrome (PCOS). Additionally, the study aims to observe the impact of the product on menstrual cycle structure and associated symptoms, on reproductive and metabolic markers, on body image concerns, anxiety and general well-being. A consumer-driven, decentralized observational clinical research study is therefore well-suited for examining the effects of this product in this population. We will examine the outcomes in a broad age-range of premenopausal women who have chosen to try this product. The study will incorporate participant reported outcome questionnaires and surveys and at-home blood specimen collection. There is no "doctor-patient" relationship as part of this research since the participant as a consumer is making the informed choice to try the product and take part in the observational process with self-reported measures, cycle tracking and at-home blood sample collection. Findings from this study will contribute knowledge toward the tolerability and formulation of the product and the design of future studies.

Participants enrolled in this study will complete a single-session, non-invasive, computerized cognitive assessment administered through a secure, web-based digital platform. The purpose of the study is to establish normative cognitive performance data from healthy adults aged 18-100 years and develop age-, sex-, and education-adjusted reference values for the digital assessment platform. This is an observational study and does not involve any therapeutic intervention, investigational treatment, or alteration of routine medical care. Following electronic informed consent, participants will complete a standardized screening questionnaire to determine eligibility. The questionnaire collects demographic information, education, English language proficiency, medical and neurological history, psychiatric history, medication use, substance use, sleep history, and self-reported cognitive concerns. Standardized mood screening instruments (PHQ-9 and GAD-7) are also administered. Individuals meeting predefined exclusion criteria that could significantly influence cognitive performance will not be included in the normative dataset. Eligible participants will then complete a digital cognitive assessment battery using standardized visual and auditory instructions. The platform utilizes automated voice-recognition technology to capture spoken responses and standardized algorithms to score performance, eliminating the need for examiner scoring and ensuring consistent administration across participants. Total study participation, including consent, screening, and testing, is approximately 30 to 45 minutes. The cognitive battery evaluates multiple cognitive domains commonly assessed during neuropsychological examinations. Language abilities are assessed through phonemic and semantic verbal fluency tasks, measuring the ability to rapidly generate words within specified categories. Confrontation naming is evaluated using digitally presented images that participants identify verbally. Learning and memory are assessed through immediate and delayed verbal recall tasks, including recognition memory measures. Attention and working memory are evaluated using forward and backward digit span tasks. Executive functioning and attention are further assessed using a brief computerized problem-solving task. Equivalent alternate versions of selected tasks may be administered to minimize practice effects while measuring the same cognitive domains. All assessments are brief, non-invasive, and completed using spoken responses. The platform automatically records participant responses, response timing, and scoring metrics. Voice recordings are collected solely to support automated scoring and quality assurance. All electronic data are transmitted using encrypted connections and stored within HIPAA-aligned cloud infrastructure. Personally identifiable information is stored separately from cognitive performance data using unique study identification numbers, and only authorized study personnel have access to identifiable information. De-identified data will be used to generate normative reference values. A subset of approximately 100 participants may be invited to complete a second assessment 2-4 weeks after the initial visit to evaluate test-retest reliability. Participation in this follow-up assessment is voluntary. Participants will not receive diagnostic results or individualized interpretations of their performance because the study is intended solely to establish normative reference data. If responses on the PHQ-9 suggest potential acute self-harm risk, the platform will provide crisis resources and notify the study team in accordance with the study safety procedures. The primary outcome of the study is the development of age-, sex-, and education-adjusted normative reference values for the digital cognitive assessment platform, supporting standardized interpretation of future assessments in clinical and research settings.

This study investigates whether transcranial electrical stimulation (tES) delivered during structured language-learning sessions affects the rate and quality of second-language acquisition in adults. Adults who are learning or planning to learn a new language are randomly assigned in equal numbers to receive either active stimulation or sham (placebo) stimulation while completing structured language-learning content. Participants wear a non-invasive transcranial electrical stimulation headset that delivers a low-level electrical current through electrodes resting on the scalp, targeting cortical regions associated with language. Sessions typically last 20 to 30 minutes and may be completed at home or in person at a participating language program. Language proficiency is measured with a standardized assessment before and after the intervention period, with additional app-derived performance metrics and participant-reported measures collected throughout. A follow-up assessment may be conducted up to 12 months after the intervention ends to evaluate whether any observed effects persist. In this study the device is applied as a learning aid in healthy adults. It is not used to diagnose, treat, cure, or prevent any disease.

Veterans with co-morbid posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) are at substantial risk of developing hypertension and cardiovascular diseases that often lead to premature death, with some evidence that they may die over 10 years earlier than their counterparts. As such, determining ways to improve their health outcomes is vital. Heart Rate Variability Biofeedback (HRVB) may be one way to restore autonomic balance and teach veterans with PTSD / SUDs how to respond differently to their symptoms. Multiple studies have found that HRVB not only improves autonomic nervous system (ANS) regulation / flexibility among veterans with PTSD, but also reduces PTSD symptoms. Additionally, there is evidence that HRVB reduces cravings and SUD symptoms. Currently it is proposed that the improvement in the PTSD and SUD symptoms are due to a combination of improving ANS regulation and veterans utilizing the HRVB techniques as coping strategies for their symptoms. Yet, none of these studies examined how HRVB versus other active interventions differentially effected symptoms and physiological outcomes. It may be useful to examine HRVB to other active interventions . The current project proposes to alleviate this gap by examining the effects of HRVB to one a active control condition (i.e., Present Centered Psychotherapy; PCT) among 50-residential veterans engaging in PTSD residential programming. Veterans will be recruited from residential programs at the Coatesville VAMC and screened for probable PTSD and an active (i.e., past year) SUD. If eligible, they will attend a brief visit that will include being randomized, engaging in a diagnostic interview, a battery of questionnaires related to PTSD / SUDs, attached to physiology equipment, and then complete 3 tasks (i.e., baseline task, emotion induction, and HRVB or Self-Compassion Break). Upon task completion, all veterans will be screened for risk and begin one of the conditions. Similar research procedures will be conducted after their final session. This study would provide evidence for the real-world effectiveness of HRVB compared to a control condition among one of the highest risk populations treated at the VA, which may provide invaluable insight into active mind-body treatments for veterans with PTSD / SUD.
