Measure of Pulse Rate Predicts Cognitive Decline in Older Adults

Source: Science Daily - Top HealthHeartbeats exhibit variation as they adjust to tiny changes in the body and environment. Researchers have applied a new way to measure the complexity of pulse rates, using data collected through wearable pulse oximetry devices. The new method, published in Journal of the American Heart Association, provides a more detailed peek into heart health than traditional measures, uncovering a link between reduced complexity and future cognitive decline.
