This program offers extra stem cells from a half-matched family donor to patients who are getting a cord blood transplant for serious blood cancers or immune disorders. The goal is to help the bone marrow recover more quickly while the cord blood cells take over permanently. It i…

This Phase 3 study tests whether the drug leriglitazone can help adult men with cerebral adrenoleukodystrophy (cALD), a rare and serious brain disease. The main goal is to see if the drug delays death or the need for permanent breathing support compared to a placebo. About 40 men…

This trial tests a gene therapy for X-linked adrenoleukodystrophy (X-ALD), a rare genetic disease that damages the brain. The therapy uses a modified virus to deliver a working copy of the faulty gene directly into the spinal fluid and bloodstream. Up to 30 patients aged 1 year a…

This early-stage trial tests whether adding special cells (DUOC-01) into the spinal fluid is safe for children with inherited metabolic diseases that damage the brain. Participants are ages 1 week to 21 years and are already receiving a standard umbilical cord blood transplant. T…

This study tests whether custom 3D-printed cutlery handles can help people with neurodegenerative diseases eat more independently. 75 patients in rehabilitation care will try handles in different sizes, designed to fit their grip. Researchers will measure changes in eating abilit…

This study compares two surgeries for stress urinary incontinence (leaking urine when coughing or sneezing) in women. One method uses a synthetic mesh sling, while the other repairs natural tissues without mesh. Researchers will track symptom improvement, recovery time, pain, and…

This study is a national registry for people with adrenoleukodystrophy (ALD), a rare genetic disorder. Researchers will collect medical records and survey data from up to 1,000 patients and their families over time to understand how the disease progresses. The goal is to find bet…

This observational study is following 32 boys aged 6 months to 17 years with Pelizaeus-Merzbacher disease (PMD), a rare genetic disorder affecting the brain's white matter. Researchers are measuring biomarkers in spinal fluid and blood, brain scans, and motor and cognitive skills…

This study looks at people with brain damage from strokes, tumors, or other conditions to understand why they have specific thinking problems. Researchers will use brain scans and cognitive tests to link brain areas to deficits. The goal is to learn more about how the brain works…

This study gathers medical information from 200 adults with possible nerve, muscle, or autonomic nervous system disorders who are not already in other NIH studies. Participants undergo standard tests like nerve conduction studies, EMG, and physical exams. The data is stored anony…

This study follows 1500 people with rare genetic brain disorders to learn how these diseases progress. Researchers measure thinking, movement, and daily living skills over time, and also look at brain scans and body fluids. The goal is to better understand the diseases and how tr…

This study follows 30 people with Zellweger Spectrum Disorder over 5 years to understand how their vision changes over time. Participants will have yearly vision tests, physical exams, and blood work. The goal is to define the course of retinal degeneration and find the best ways…

This study follows 200 people with Alexander Disease, a rare brain disorder, to learn how the disease changes over time. Researchers measure movement, speech, swallowing, and quality of life, and collect blood and spinal fluid samples. The goal is to gather information that will …

This study follows up to 600 people with leukodystrophy, a rare genetic disorder affecting the brain's white matter. Researchers aim to track how the disease progresses, improve diagnosis through genetic testing and brain scans, and evaluate outcomes like hospitalizations and res…

This study aims to learn more about rare genetic diseases that affect both the immune system and the nervous system. Researchers will collect medical information and samples from 1,000 participants, including patients, their relatives, and healthy volunteers. The goal is to bette…

This study is looking at how people with conditions like schizophrenia, bipolar disorder, depression, and neurological diseases (such as Alzheimer's or stroke) perform on computer-based thinking tests. The goal is to create a detailed map of cognitive strengths and weaknesses acr…

This study follows people with peroxisome biogenesis disorders (PBD) to learn more about how the disease progresses. Researchers will collect medical records, test results, and images over time from up to 244 participants. No new treatments are being tested; the goal is to better…
