Neuronal ceroid lipofuscinosis 7

This study tests a new type of stem cell transplant for children with primary immune deficiencies or inherited metabolic disorders. The transplant uses stem cells from a half-matched family donor, which are specially processed to remove certain immune cells. The goal is to see if…

This study tests a bone marrow transplant from a family donor for children under 21 with severe non-cancer blood disorders like sickle cell disease, bone marrow failure, or immune problems. The goal is to see if the transplant can replace the diseased cells with healthy donor cel…

This study looks at whether eating cottonseed oil just three times a week can help lower cholesterol and reduce heart disease risk. Researchers will give 75 overweight or at-risk adults meal replacement shakes with different amounts of cottonseed oil for 56 days. They will measur…

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 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 aims to better understand and treat people with certain inherited metabolic or genetic disorders. Researchers will use standard medical tests like blood work and imaging to diagnose and care for participants, who may also join other related studies. The goal is to expa…

This study looks at children with suspected or confirmed genetic and metabolic disorders to find new disease-causing gene mutations. Researchers will analyze blood samples for DNA and metabolites, and in some cases take a small skin sample. The goal is to better understand these …

This study at Necker Hospital in Paris is checking how well patients with inherited metabolic diseases follow their daily oral medication routines. About 200 patients (children aged 7 and up, teens, and adults) will fill out a questionnaire during a regular visit. The goal is to …

This study enrolls up to 15,000 children with known or suspected endocrine or metabolic disorders, along with their family members. Researchers will collect medical records, blood, saliva, and other samples to identify genetic changes linked to these conditions. The goal is to be…

This study is creating a large collection of blood, urine, stool, and heart tissue samples from 10,000 people with and without heart or metabolic conditions. The goal is to store these samples along with medical information to speed up future research into what causes these disea…

This study tests a new communication tool called 'Let's Get REAL' that helps children and teens (ages 8-17) and their families talk together about stem cell transplant or cellular therapy decisions. The goal is to see if the tool is easy to use and helpful for families. About 60 …

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 300 people with CLN3 Batten disease, a rare genetic disorder that causes vision loss, seizures, and decline in thinking and movement. Researchers collect samples like blood and spinal fluid to find biological markers that could be used in future treatment trial…

This study uses MRI scans to look for brain differences in people with metabolic diseases compared to healthy volunteers. Researchers will track changes over time and link them to body fat and other health measures. About 126 adults will take part at Ulm University Hospital. No d…

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 looks at whether using a swallow gel or a semi-solid vehicle can help people with neurological conditions swallow pills more easily and safely. Researchers will observe 500 participants, including patients with swallowing disorders and healthy volunteers, as they swall…

This study looks at how often young children (ages 1 to 6) with inherited metabolic diseases develop eating disorders when they are on special diets. Researchers will use a feeding scale to measure eating problems in 200 children. The goal is to understand the link between these …

The SMILE study is tracking 10,000 adults aged 18 and older to see how sarcopenia (age-related muscle loss) and metabolic diseases like diabetes influence overall health and lifespan. Researchers will collect data from medical records, tests, and surveys over time. This is an obs…

This study looks at how lipoproteins—tiny particles that carry cholesterol in the blood—work in healthy people and those with lipid disorders like high cholesterol. The goal is to understand how these particles affect heart and blood vessel health, especially when they don't func…

This study follows 500 children and adults with Batten disease to learn how the condition naturally changes over time. Researchers will measure movement, thinking, behavior, and daily function using a special rating scale. The goal is to better understand the disease and improve …

This study follows 100 children under 18 who are already on a ketogenic diet for conditions like drug-resistant epilepsy, autism, chronic migraine, or brain tumors. Researchers want to see if the diet supports healthy growth, improves symptoms, and boosts quality of life. The die…
