How exercise-related blood flow affects brain control of balance in older adults
Investigating cerebrovascular regulation during exercise as a factor influencing cortical resource engagement for balance control with aging
This work looks at whether changes in blood flow during exercise change how older adults' brains manage balance, especially for people with genetic risk for Alzheimer's.

What this research studies
You would be asked to come to the lab for in-person visits where researchers measure blood flow and brain activity while you do short bouts of exercise and standing balance tasks. They will record brain signals using EEG during balance reactions and compare how blood flow and brain activity link to balance performance. The team will also consider genetic risk (APOE4) to see if people with higher Alzheimer’s risk show different patterns. Results aim to show who is more likely to rely on thinking to keep balance and how that relates to fall and dementia risk.
Who could benefit from this research
Good fit: Ideal participants are older adults who can perform brief exercise and standing balance tests, including people with or without the APOE4 genetic risk for Alzheimer's.
Not a fit: People with advanced dementia, severe mobility limitations, or who cannot attend in-person lab visits are unlikely to be able to participate or benefit directly from this project.
Why it matters
Potential benefit: If successful, this work could point to ways exercise or blood-flow-focused approaches might reduce balance-related falls and inform personalized prevention for people at risk of dementia.
How similar studies have performed: Previous research links lower cerebral blood flow and APOE4 to worse cognition and balance under load, but combining exercise blood-flow measures with EEG during real-time balance tasks is a relatively new approach.
