This study uses a special PET scan to look at tau protein buildup in the brains of African Americans who are either cognitively normal or have dementia. Researchers hope to learn how these brain changes differ across racial groups. The study involves 240 participants and uses a t…

This study follows 350 people who survived a brain bleed (intracerebral hemorrhage) and were part of earlier trials. Researchers will test memory, thinking, and movement skills over time, and collect blood samples to look for signs of ongoing inflammation. The goal is to see if s…

This study looks at 45 people having carotid artery surgery to see if special brain scans can predict improvements in thinking and memory. Researchers will use PET/CT scans to measure inflammation in the brain and MRI to examine plaque in the carotid artery. The goal is to find i…

This study tracks 100 healthy children aged 6 to 16, testing their thinking skills twice over a year. The goal is to create more accurate standards for measuring normal cognitive development. This could help doctors better identify when a child's thinking abilities change due to …

This study aimed to understand how blood pressure changes when standing up affect thinking abilities and brain blood flow in people with Parkinson's disease. Researchers planned to compare participants with and without orthostatic hypotension (low blood pressure upon standing) us…

Researchers at Stanford are creating a database to better understand why some older adults experience memory or thinking problems after surgery with anesthesia. They will collect information from 250 patients aged 65 and older, including blood samples, brain wave recordings, and …

This study looks at whether young adults (ages 21-25) who use high-potency cannabis concentrates can improve their memory and thinking by switching to less potent products. Researchers will test participants' cognitive performance and collect blood and urine samples. The goal is …

This study tests a new type of PET scanner that can take pictures of most of the body at once, instead of just a small section. Researchers want to see how well this scanner works in healthy adults and people with memory problems. The goal is to gather information to improve futu…

This study looks at whether doing brain-training exercises in the morning or the afternoon helps older adults (60+) recover thinking skills after a stay in the intensive care unit. Forty participants will either train in the morning, in the late afternoon/evening, or receive usua…

This study follows 312 older adults who survived a critical illness to see how much they moved during their ICU stay. Researchers want to learn if more activity leads to less disability, better mobility, and clearer thinking 3 to 12 months later. The goal is to find ways to impro…

This study looks at why over half of ICU patients develop severe muscle weakness that can last for months or years. Researchers will use muscle biopsies, ultrasound, and strength tests on 50 critically ill adults to find better ways to diagnose and track this condition. The goal …

This study follows 432 adults who were in the ICU after a traumatic injury or burn. Researchers want to see if and why patients develop long-term problems with memory, thinking, and daily function. By tracking cognitive skills and inflammation over time, they hope to uncover link…
