This study looks at whether a virtual reality (VR) education program can improve how nursing students in Indonesia think and feel about people with dementia. About 200 students will take part in a single 100-minute class that includes VR experiences, lectures, and discussions. Th…

This study uses a safe, painless eye scan called OCT to look at support cells (glia) in the retina, which is part of the brain. Researchers want to see if these cells work differently in people with early signs of Alzheimer's compared to those without. If they find a difference, …

This study follows 192 teens aged 12 to 20 who are already receiving either Cognitive Behavioral Therapy (CBT) or Brief Strategic Therapy (BST) for anxiety, depression, or OCD. Researchers will track their progress using questionnaires and interviews over 9 months. The goal is to…

This study interviews 6 healthcare support workers in a hospital to understand how they handle distressed behavior in people with dementia. The goal is to learn from their experiences and identify what training might help them better support patients. It is an observational study…

This study uses a special brain scan called Tau PET to look at a protein linked to Alzheimer's disease in healthy older African Americans. Researchers want to learn how this protein builds up and relates to memory changes over time. The goal is to better understand early signs of…

This study follows 130 older adults with mild to moderate Alzheimer's for up to 5 years to see if frailty (weakness, slow walking, exhaustion, weight loss, low activity) leads to faster loss of daily living skills. Participants are tested at the start and after one year, with lon…

This study is testing whether simple blood tests can accurately diagnose dementia in everyday clinic settings. Over 3,000 people aged 45 and older with memory problems will give blood samples and answer questionnaires. Researchers will check how reliable and acceptable these bloo…

This study tests whether a scenario-driven virtual reality game can improve nursing students' attitudes and knowledge about dementia. 200 Indonesian nursing students will be assigned to different combinations of VR and classroom education. The goal is to see if interactive VR hel…

This study looks at whether giving older adults (ages 60-79) personalized advice and extra support helps them follow brain-healthy habits like a Mediterranean diet, exercise, and staying socially active. Participants have mild memory concerns or are at risk for cognitive decline.…

This study aims to learn more about diseases that affect the brain, such as Parkinson's disease and different types of dementia. Researchers will follow 500 adults with symptoms of these conditions over time, using brain scans and genetic tests to see how the diseases progress. T…

This study uses special brain scans (tau PET) to see how anti-amyloid immunotherapy affects tau protein buildup in people with mild Alzheimer's disease. About 135 participants will get two tau PET scans—one before starting treatment and another 12-18 months after finishing it. Th…

This study follows 600 people with and without chronic kidney disease (CKD) for up to four years to compare how often memory loss, confusion, and daily activity problems occur. Researchers will also look for risk factors that make thinking and memory worse in CKD patients. Partic…

This study uses blood samples and health data from over 13,000 older adults to see if Alzheimer's-related blood markers differ between men and women. Researchers aim to create a sex-specific risk score that could help predict the disease earlier and personalize future treatments.…

This study follows over 19,000 older adults who previously took aspirin in a clinical trial. Researchers are monitoring them for delayed effects on cancer, dementia, disability, and death. The goal is to see if aspirin has any long-term benefits or risks years after stopping the …

This study looks at how often antiepileptic drugs (AEDs) are prescribed to long-stay nursing home residents with dementia, especially before and after the COVID-19 pandemic. Researchers will analyze data from millions of residents to see if these medications are being used more, …

This study involves 400 healthy adults aged 60-85 to test new computerized measures of thinking and daily function. Participants are randomly assigned to take either the new tests or standard tests over one year. The goal is to see if the new tests are better at detecting changes…

This study compares two different radioactive tracers used in PET scans to measure tau tangles in the brain, a hallmark of Alzheimer's disease. Researchers will scan over 800 participants with either Flortaucipir or MK-6240 to see how well they work over time. The goal is to harm…

This study follows 1,400 people with early-stage Alzheimer's or mild cognitive impairment to understand how the disease affects healthcare costs and daily life over time. Participants are not given any experimental treatment. The goal is to gather information for research purpose…
