Test of an adjustable valve system for hydrocephalus shunts
This trial checks how safe and well a specific adjustable valve (Polaris 24) works in people with hydrocephalus who need a valve shunt. You may be eligible if you already have this valve implanted for a first shunt, a shunt replacement, or after an endoscopic procedure failed, and you do not have certain infection, bleeding, or heart-circulation conditions.
MarseilleAges Any age - NCT04746820Recruiting
Brain monitoring in unconscious ICU patients after cardiac arrest
This trial tests a bedside brain-monitoring method (near-infrared light and EEG) in people who are unconscious after severe brain injury from cardiac arrest. The goal is to see whether it can help measure brain function during the first week after admission.
Zurich, Canton of ZurichAges 18 years+ - NCT04748640RecruitingPhase 2/Phase 3
Gamma Knife treatment for both-sided essential tremor
This study tests a focused radiation procedure (Gamma Knife) to treat the opposite side of the tremor in people with essential tremor. It may help improve tremor-related quality of life if your side that wasn’t treated before is still causing problems.
Toronto, OntarioAges 18 years+ - NCT04748601RecruitingPhase 4
Qudexy XR to help prevent migraine in kids ages 6 to 11
This study tests whether Qudexy XR can reduce migraine headaches in children ages 6 to 11. It looks for kids who are having frequent, disruptive migraine attacks and checks safety with careful medication rules.
Birmingham, AlabamaAges 6–11 - NCT04750928RecruitingPhase 1/Phase 2
Abemaciclib for NF1 tumors using pills and body scans
This trial studies whether the medicine abemaciclib can shrink or slow the growth of “atypical neurofibromas” in people with NF1. Participants take pills and undergo regular check-ups, including MRI scans to measure the tumor.
Bethesda, MarylandAges 12 years+ - NCT04752293Recruiting
Study of a kidney blood-pressure system in kids
This study looks at how a kidney-related blood-pressure system works in children and teenagers, comparing those with newly diagnosed primary (no known cause) high blood pressure to those with normal blood pressure. It may help doctors better understand childhood blood-pressure changes and guide future care.
Winston-Salem, North CarolinaAges 7–18 - NCT04755101Recruiting
Right-sided ablation for fainting caused by heart nerve signals
This trial studies a procedure that targets a specific heart nerve area on the right side to reduce neurally mediated fainting (syncope). You may be a candidate if your fainting is linked to heart rhythm/nerve reflexes and you meet several heart-function and heart-rhythm test criteria.
BonheidenAges 14 years+ - NCT04755205Recruiting
Natural history study of olfactory neuroblastoma
This study follows people with olfactory neuroblastoma over time to better understand how the disease behaves and changes. It may help future patients by improving doctors’ knowledge, even if it does not test a new treatment.
Bethesda, MarylandAges 3–120 - NCT04755699RecruitingEarly Phase 1
Electrical stimulation study for hand or limb movement recovery
This early-stage study tests whether regular, skin-based electrical stimulation can help people with paralysis or weakness regain movement. You would attend frequent clinic sessions for months, while the team checks your ability to follow instructions and your safety.
Manhasset, New YorkAges 18–75 - NCT04758624Recruiting
Study brain changes after deep brain stimulation for tremor
This study looks at how brain “wiring” (connectivity) and brain function change over time in people with essential tremor after successful deep brain stimulation. You might benefit by helping researchers better understand what DBS does in the brain, which can improve care for others with tremor.
Manhasset, New YorkAges 18–85 - NCT04757220Recruiting
Study of apathy in people with schizophrenia or depression
This study looks at “apathy,” or reduced motivation/interest, in people with schizophrenia or depression. It may help researchers understand what drives apathy and how to measure it in a clearer, more complete way.
StrasbourgAges 18–60 - NCT04759326Recruiting
Hippotherapy after stroke to improve movement and function
This trial studies whether therapy using a horse (hippotherapy) can help adults who still have stroke-related physical difficulties more than 3 months after their stroke. It aims to improve daily function and movement when standard recovery has not been enough.
La CanourgueAges 18 years+ - NCT04759443Recruiting
