This study looked at driving skills in 60 people over age 70 with early-stage Alzheimer's disease (MMSE score 24 or higher) and compared them to healthy older drivers. The goal was to identify common driving mistakes and suggest adaptive measures or technology to help them drive …

This study looked at how giving people information about their genetic risk for Alzheimer's disease affects them emotionally and behaviorally. It involved 374 Latino adults aged 40-64 in New York City who did not have Alzheimer's. Some participants learned their risk based only o…

This completed study from the University of East Anglia looked at how gut bacteria break down certain plant compounds (flavan-3-ols) in people with different versions of the APOE gene, which is linked to Alzheimer's risk. 49 healthy adults donated stool and saliva samples. The go…

This completed study analyzed blood test results from 100 people over age 50 to see if there is a connection between gum inflammation and Alzheimer's disease. Researchers measured gum health and looked at various blood cell counts. The goal was to find blood markers that might li…

This study looked at whether shining a special light on the head (called transcranial photobiomodulation) can improve blood flow in the brain and boost thinking skills. 24 healthy adults aged 18 to 80 took part. The goal was to gather information, not to treat or cure any disease…

This study looked at how people with dementia with Lewy bodies experience their sense of self, including memory and self-concept. Researchers compared 61 participants with dementia, Alzheimer's, and healthy aging using memory tests and brain scans. The goal was to understand whic…

This completed observational study looked at whether poor sleep quality, specifically slow wave sleep, is linked to brain changes that raise Alzheimer's risk, and whether this link differs between African-American and white older adults. Researchers recruited 210 cognitively norm…
