Interactions between blood pressure variability, cerebral autoregulation, and covert cerebral small vessel disease in relation to cognitive performance in community‐dwelling older adults

Key Points

• This research aims to understand how blood pressure variability and cerebral autoregulation relate to cognitive performance in older adults.
• Analyzed interactions between blood pressure variability and cerebral autoregulation
• Assessed cognitive performance among community-dwelling older adults
• Considered the presence of cerebral small vessel disease as a covariate
• Found that increased blood pressure variability is associated with poorer cognitive performance
• Impaired cerebral autoregulation showed similar associations
• Independent of detectable cerebral small vessel disease, these factors suggested a link to cognitive vulnerabilities
