This study tests a liquid form of the seizure drug zonisamide in children aged 1 month to 17 years who have partial-onset seizures. The goal is to find the right dose and check for side effects. About 40 children will take the medicine for up to 12 weeks, with a follow-up visit o…

This study looks at the best way to switch children with Dravet or Lennox-Gastaut syndrome from artisanal (non-pharmaceutical) cannabidiol to Epidiolex, an FDA-approved CBD medication. About 25 children aged 2 to 18 will gradually increase their Epidiolex dose while reducing thei…

Researchers are testing whether MRI-guided high-intensity focused ultrasound can safely reduce seizures in adults with generalized epilepsy that does not respond to medication. The procedure uses sound waves to precisely target and ablate a small brain region involved in seizure …

This study tests whether a training program that pairs sounds with visual cues can help people who have lost part of their vision due to brain damage (cortical blindness). Participants will do 12 sessions where they see and hear stimuli in their blind area, plus virtual reality t…

This study tests a caregiver-led digital program called VIPPSTAR designed to improve vision and brain development in infants at risk of or with visual impairment. The program provides personalized activities integrated into daily routines, supported by remote coaching. Researcher…

This study tests an oral drug, AV078, in people aged 12 and older with tuberous sclerosis complex (TSC) whose seizures are not controlled by standard medications. Participants are randomly assigned to receive AV078 or a placebo for 12 weeks. The goal is to see if AV078 safely red…

This study tests an oral drug called glycerol tributyrate in 24 adults with MELAS or LHON-Plus, two rare mitochondrial diseases that cause severe symptoms like strokes and vision loss. The trial is open-label (everyone gets the drug) and uses each person as their own control over…

This trial tests a new device called the enVVe system, a catheter-based artificial valve placed in leg veins to treat chronic venous insufficiency. The study will enroll 220 people with severe symptoms like skin changes or leg ulcers. Participants are randomly assigned to receive…

This study tests whether levetiracetam, a seizure medication, works as well as magnesium sulfate to prevent seizures in pregnant people with severe preeclampsia. About 1,240 participants at 32 weeks or more will be randomly assigned to one of the two drugs. The goal is to see if …

This trial investigates whether a home-based self-management program called HOBSCOTCH can improve thinking, memory, and quality of life in young adults (ages 18–29) and youth (ages 13–17) with epilepsy. Participants attend nine weekly one-on-one coaching sessions by phone or comp…

This study tests a non-invasive technique called temporal interference stimulation to boost deep sleep in people with epilepsy. Researchers will compare 4 nights of real stimulation to 4 nights of sham (fake) stimulation in up to 16 patients. The goal is to see if better sleep ca…

This study tests a training technique that uses repeated flashes of light and bursts of sound to help people who have lost part of their vision after a stroke. The goal is to see if this training can improve how much they can see and how their brain responds. The study will inclu…

This study tests a 3-week digital program delivered through the VIPPSTAR app, designed to help children and adolescents with visual impairment build a healthier body image and become more critical of social media content. Participants aged 10-18 will complete daily exercises and …

This study tests a 12-week adapted physical activity program for children and adolescents aged 10-17 with visual impairment. The program includes supervised school-based exercise sessions and home-based activities, along with peer-group meetings to promote social inclusion. Resea…

This study explores how visual impairment affects movement and daily activities, and tests a wearable system called VIS4ION that provides audio and touch cues to help users navigate. Researchers will enroll 150 adults with visual impairment and healthy controls to see if the devi…

This study looks at whether a common procedure for varicose veins—called endovenous ablation—can also reduce knee pain in people aged 80 and older. The researchers will follow 50 participants for one year after treatment, measuring pain and knee function. The goal is to see if im…

Researchers are observing patients in China who have both a tumor in the sellar region of the brain and an unruptured intracranial aneurysm. The study compares three approaches: removing the tumor before treating the aneurysm, treating the aneurysm before removing the tumor, or r…

This study will test whether using virtual reality headsets raises the risk of seizures in adolescents and adults with epilepsy. Forty participants will wear a VR headset while their brain activity is recorded with EEG, comparing periods with the display off, on, and with hand co…

This observational study will track 87 people who are already scheduled to receive treatment with the Recana Thrombectomy Catheter System for blocked veins in their legs. The goal is to see how safe the device is and how well it works at clearing the blockages during the procedur…

This study investigates how a drug called Cobenfy KarXT, which affects the brain's cholinergic (acetylcholine) system, alters brain activity during memory and thinking tasks. About 30 people with essential tremor or epilepsy who are already scheduled for deep brain stimulation (D…

This study looks at whether insurance claims data can be used to reliably identify two serious complications in people with Alzheimer's disease: brain hemorrhages larger than 1 cm and new-onset seizures. Researchers will analyze records from 600 Alzheimer's patients, linking insu…

This study investigates whether people with central or peripheral vision loss develop heightened senses of taste and smell. Researchers will measure brain responses to sweet and vanilla flavors in 50 visually impaired adults and compare them to sighted controls. The goal is to un…

This study looks at whether shifting text to a different part of the eye can help people with central vision loss read faster and more accurately. Researchers will test 100 participants with conditions like macular degeneration using various reading tasks. The goal is to find bet…

This early-phase study tests whether the drug Cobenfy KarXT can change brain activity linked to memory in 50 adults with epilepsy who are already scheduled for brain surgery. Participants will take either the drug or a placebo on separate days and perform memory tasks while their…

This study looks at children born prematurely who had retinopathy of prematurity (ROP), a disease that can cause blindness. Some were treated with laser, others with injections, and some had ROP but no treatment. Researchers will compare their vision and retina structure to see w…

This study will follow 200 children with epilepsy to find clues—like brain scans or EEG patterns—that show which kids are likely to become resistant to standard seizure medications. The goal is to catch these cases early and consider alternative treatments such as a ketogenic die…

This study will track 139 newborns who have seizures in their first month of life to learn how common these seizures are, what causes them, and how the babies fare during their hospital stay. Researchers will use exams, blood tests, and brain scans to gather information. The goal…
