This early-phase study tested a gene therapy that delivers a protective protein (GDNF) directly to the brain in 25 people with advanced Parkinson's disease. The goal was to see if it is safe and to gather early information on whether it might help protect dopamine-producing brain…

This study tested a gene transfer treatment for giant axonal neuropathy (GAN), a rare genetic disease that damages nerves and affects movement, breathing, and other functions. Fourteen people aged 3 and older received a single injection of the treatment into the fluid around the …

This early-phase study tested whether infusing virus-fighting immune cells from a healthy donor could safely treat progressive multifocal leukoencephalopathy (PML), a serious brain infection in people with weak immune systems. Sixty adults with PML received up to three infusions …

This early-phase study tested a drug called NT-I7 in 12 adults with progressive multifocal leukoencephalopathy (PML), a serious brain infection that occurs in people with weakened immune systems. The goal was to see if NT-I7 could increase the number of infection-fighting white b…

This study used brain imaging to understand how Parkinson's disease changes the brain over time. Researchers compared people with definite or possible Parkinson's to healthy volunteers. Participants had up to six visits over nine years, including MRI scans and symptom checks. The…

This study looked at 85 people with tremor conditions like Parkinson's disease, essential tremor, and dystonia, plus healthy volunteers. Researchers used tests like brain scans, electrical recordings, and movement tasks to learn how the brain controls movement and what goes wrong…

This early-phase study tested whether ferumoxytol, an iron-based contrast agent, can help MRI scans better detect inflammation in the brains of people with multiple sclerosis (MS). Fourteen participants (some with MS, some healthy) received a single IV dose of ferumoxytol and had…

This completed study from the National Institute of Neurological Disorders and Stroke aimed to better understand how the brain controls movement and what goes wrong in movement disorders like Parkinson's disease, Tourette's syndrome, and dystonia. Over 1,200 adults—both patients …

This study followed 50 adults with a C9ORF72 gene mutation that can cause ALS or frontotemporal dementia. Over three years, researchers measured changes in strength, thinking, memory, and behavior using brain scans, spinal fluid tests, and other assessments. The goal was to under…

This completed study screened over 3,800 people with neurological conditions, their family members, and healthy volunteers. The goal was to gather information and create a pool of potential participants for future research studies. No experimental treatments were given, and docto…

This study followed 180 adults with syringomyelia, a condition where a cyst forms in the spinal cord, for up to 5 years. Researchers tracked symptoms, muscle strength, and MRI scans to learn how the disease progresses and how surgery affects outcomes. The goal was to gather knowl…

This study aims to improve how doctors test for autonomic failure, a condition where the body's automatic functions like blood pressure control don't work properly. Researchers will use advanced imaging, sweat tests, and skin biopsies in up to 89 adults with Parkinson's disease, …

This study looked at the genetics of Chiari I malformation, a condition where part of the brain pushes into the spinal canal. Researchers analyzed DNA and family histories from 152 participants to find genes that may cause the malformation. The goal was to better understand why i…

This study used PET and MRI brain scans to measure how a brain chemical called acetylcholine works in people with dystonia, a condition that causes involuntary muscle twisting. Researchers compared 31 adults with cervical or DYT1 dystonia to healthy volunteers. The goal was to be…

This study looked at children who survived Ebola and compared them to close contacts who never got sick. Researchers checked for brain, nerve, and thinking problems more than 5 years after infection. The goal was to understand what lasting issues survivors face, not to test a tre…

This completed early-phase study tested how different types of noninvasive brain stimulation—like magnetic or electrical pulses—affect motor function in healthy adults. Over 1,000 participants took part in up to 20 sessions each, with researchers measuring brain activity and move…

This study looked at 886 adults with suspected traumatic brain injury to better understand how the brain changes after injury. Participants had MRI scans, blood tests, and thinking tests within 48 hours of injury, with optional follow-ups up to a year. The goal was to find better…

This study looked at how different layers of the brain's motor cortex help us learn and remember new movement skills. Forty healthy, right-handed adults practiced typing sequences and had their brains scanned with MRI. The goal was to see which brain layers are most active during…

This study looked at 78 women to understand why chronic pelvic pain happens in endometriosis. Researchers examined hormones, immune chemicals, and genes, and how nerves and muscles are involved. Participants included women with endometriosis and pain, those with pain but no endom…

This study tested a new risk score that combines genetic and environmental factors to predict multiple sclerosis (MS). Researchers studied 181 people, including MS patients and their close relatives. The goal was to see if this score could identify who might develop MS in the fut…

This completed study followed 81 adults who had stroke-like symptoms to see how damage to the blood-brain barrier relates to white matter changes in the brain. Over 6 years, participants had regular MRI scans and thinking tests. The goal was to better understand why some people d…

This study looked at 13 adults who had COVID-19 and still had symptoms like memory or nerve problems after recovery. Researchers used brain scans, memory tests, smell tests, and other exams to find possible changes in the nervous system. The goal was to better understand how COVI…

This study tested whether a single dose of pembrolizumab, a cancer drug, is safe for people with HIV who do not have cancer. The goal was to see if the drug could help reveal HIV hiding in the brain. Thirteen adults with well-controlled HIV participated. The study was not meant t…

This study looked for early biological signs (biomarkers) of Parkinson disease in 89 people with certain risk factors, such as family history, loss of smell, blood pressure drops, or a sleep disorder. Participants underwent brain scans, spinal taps, and other tests over several y…
