Is reduced heart rate variability associated with cognitive impairment in older disabled women?
Reduced heart rate variability is independently associated with cognitive impairment in older disabled women, suggesting a link between cardiac autonomic dysfunction and cognitive decline.
Cardiac autonomic dysfunction, particularly decreased parasympathetic activity, was independently associated with cognitive impairment in older disabled women in the community. This finding may improve understanding of the pathophysiological basis of cognitive impairment. The potential role of HRV as a cause or consequence of cognitive impairment needs to be elucidated in future studies.
