How Alzheimer's risk factors affect reactive astrocyte activity (a form of brain inflammation)
The relationship of AD risk factors to reactive astrogliosis along the Alzheimer's disease continuum
This project sees if cardiovascular risk factors and poor sleep are linked to increased astrocyte-related brain inflammation in people across the Alzheimer's spectrum.

What this research studies
You would be asked to have your heart and blood-vessel health and sleep patterns measured, get brain scans for amyloid, and possibly give blood or cerebrospinal fluid samples to check markers of astrocyte inflammation. Researchers will combine those measures with memory and thinking tests over time to see whether vascular risks and poor sleep relate to more astrocyte activity and faster memory decline. They will specifically track blood pressure, arterial stiffness, and cholesterol alongside amyloid levels to understand how these vascular factors interact with brain changes. The goal is to connect modifiable risks like sleep and heart health to a specific inflammatory brain response that may drive Alzheimer's progression.
Who could benefit from this research
Good fit: Older adults across the Alzheimer's spectrum — including people with normal cognition, mild cognitive impairment, or Alzheimer's dementia — especially those with cardiovascular risk factors or sleep problems, would be ideal candidates.
Not a fit: People without Alzheimer's-related brain changes, those with non-Alzheimer's dementias, or individuals unwilling to undergo imaging or lumbar puncture are unlikely to receive direct benefit from participation.
Why it matters
Potential benefit: If successful, this work could point to heart- and sleep-related targets to reduce harmful brain inflammation and slow Alzheimer's-related decline.
How similar studies have performed: Previous studies have linked poor sleep and cardiovascular risk to amyloid buildup and memory loss, but using astrocyte-related inflammation as the connecting mechanism is a newer approach.
