NCT06410157 | NOT YET RECRUITING | Age-related Cognitive Decline

Heartrate and Breathing Effects on Attention and Memory
Sponsor:

University of Southern California

Information provided by (Responsible Party):

Mara Mather

Brief Summary:

Some types of meditation lead heart rate to become more steady as breathing quiets whereas others lead to large heart rate swings up and down (oscillations) as breathing becomes deeper and slower. The current study is designed to investigate how daily practice of heart rate biofeedback during breathing in a pattern that either increases or decreases heart rate oscillation affect attention and memory and blood biomarkers associated with Alzheimer's disease.
