Heart and Brain: Heart rate variability links to cognition?
The autonomic nervous system consists of two subsystems: flight and fight activity (sympathetic drive) and rest and digest activity (parasympathetic drive). Heart rate variability (HRV) is a non-invasive analysis of the interplay between these autonomic branches. Our research investigates the relationship between the autonomic nervous system measured by HRV and cognitive function. Specifically this project explores the potential use of HRV as an early biomarker for determining who is at risk for mild cognitive impairment. Mild cognitive impairment is an earlier stage that precedes dementia. Thus, early identification of mild cognitive impairment would facilitate the application of timely and preventative intervention measures to delay or prevent cognitive decline and ultimately dementia. The most common form of dementia, Alzheimer’s disease, is a progressive disease with no known cure, thus a focus on early detection and prevention is crucial.
