Exploring how sleep and physical activity affect brain health in aging and Alzheimer's disease
Official title: Insights into Cognitive Resilience: Sleep, Physical Activity, and Neuroimaging Biomarkers in Aging and Preclinical Alzheimer's Disease
Funded at Johns Hopkins University · NIH-11108621 · Data updated 2026-11-12
This study is looking at how things like sleep and exercise can affect brain health in older adults and those at risk for Alzheimer's, to see if making changes in these areas can help keep their minds sharp as they age.

Who could benefit from this research
✓Could help
Ideal candidates for this research include older adults and individuals showing early signs of Alzheimer's disease or related dementias.
✕Less likely to help
Patients with advanced Alzheimer's disease or other severe cognitive impairments may not benefit from this research.
What this research studies
This research investigates how lifestyle factors like sleep and physical activity can influence cognitive resilience in older adults and those at risk for Alzheimer's disease. By using actigraphy to monitor physical activity and sleep patterns, along with advanced neuroimaging techniques, the study aims to uncover the relationships between these factors and brain health over time. Participants will be monitored longitudinally to assess how changes in their activity and sleep may correlate with cognitive function and brain structure. The goal is to identify modifiable factors that could help maintain cognitive health as people age.
Why it matters
Potential benefit: If successful, this research could lead to new strategies for enhancing cognitive resilience and delaying the onset of Alzheimer's disease symptoms.
How similar studies have gone: Previous research has shown promising results in understanding the impact of lifestyle factors on cognitive health, making this approach both relevant and potentially impactful.
