AUTONOMIC DYSFUNCTION

This study tests whether intravenous immunoglobulin (IVIG) can reduce symptoms of autonomic dysfunction—such as dizziness, rapid heartbeat, and fatigue—in people with long COVID. Two hundred participants will receive either IVIG or a placebo (saline) for 9 months, plus coordinate…

This study explores whether low-intensity focused ultrasound (LIFU) aimed at specific brain regions can influence how the body controls automatic functions like heart rate and blood pressure. Researchers will apply LIFU or a sham (fake) version to 80 volunteers and measure change…

This study aims to better understand the autonomic nervous system (ANS), which controls things like heart rate and breathing without us thinking about it. Researchers will use simple, noninvasive tests (like cold water and deep breathing) to measure how the ANS responds in 48 hea…

This study was designed to understand heart rate and sleep issues in adults who survived childhood cancer. Researchers planned to use a smartphone app and wearable device to compare survivors with their siblings. The goal was to identify who is most at risk and develop ways to pr…

This study looks at what happens in the body to cause POTS and dysautonomia after viral infections, including COVID-19. About 100 women will give a blood sample and share medical records. Researchers will study immune system markers to find clues that could lead to better diagnos…

This study looks at how changing your body position or drinking water can cause temporary spikes in eye pressure. Researchers will measure these changes in healthy volunteers and in people with glaucoma or autonomic dysfunction. The goal is to better understand what challenges th…

This study looks at how insulin in the brain changes blood flow and nerve signals in healthy adults aged 18-45. Researchers will measure blood flow in the brain and legs, as well as nerve activity. The goal is to understand basic body functions, not to treat any disease.
