This study is testing a new DNA-based test called Delve Detect CSF that looks for germs in spinal fluid. The goal is to see if using this test early, instead of as a last resort, helps doctors diagnose brain infections faster. About 400 people with suspected brain infections will…

This study tests a powered leg brace called the Nomad in 36 people who have trouble walking due to conditions like stroke, multiple sclerosis, or spinal cord injury. Participants will use the brace at home for three months to see if it improves their walking speed, balance, and q…

This study tests whether whole-body electrical muscle stimulation (WB-EMS) can help adults with neuromuscular diseases like ALS, SMA, and muscular dystrophy exercise safely. Because these conditions weaken the nerves that control muscles, traditional exercise is often too hard. W…

This study looks at how the immune system changes with age and how that affects the risk of infections in people 60 and older. Researchers will collect blood, urine, stool, and other samples from elderly patients with infections and healthy older adults. By analyzing immune cells…

This study aims to learn more about how infections and inflammation harm the brain and nerves. Researchers will collect samples and perform tests on people aged 2 and older who have or may have these conditions. The goal is to better understand these diseases so that better tests…

This study aims to improve how doctors evaluate and manage people who have been exposed to bioterrorism agents (like anthrax) or emerging infectious diseases (like SARS or new flu strains). Up to 200 participants, including patients and healthcare workers, will be monitored and t…

This study tests a new, lightweight ultrasound device called NeoDoppler that can be gently placed on a newborn's soft spot (fontanelle) to continuously measure blood flow in the brain. Researchers will enroll 180 preterm and full-term infants, including those with conditions like…
