Slower Reactions in Elderly May Signal Cardiovascular Distress, Not Just Aging

A slower reaction time in elderly individuals might be a critical warning sign of underlying cardiovascular problems, rather than simply a natural part of aging or cognitive decline, according to a physician. Dr. Fu Yuxiang, director of Xiangzhan Clinic for Geriatric Medicine, highlights that families often misinterpret a slower response or reduced activity as signs of dementia or laziness.

Elderly people's reaction speed slows down, don't just think it's aging or dementia; it might be a warning sign from the cardiovascular system.

However, recent research published in JAMA Network Open suggests a more serious connection. The study tracked community-dwelling older adults and discovered that those who later experienced cardiovascular events showed a faster rate of cognitive decline three to eight years prior. Processing speed, the ability to receive, understand, judge, and react to information, was the earliest cognitive function to show differences.

Dr. Fu emphasizes that while slower reactions do not automatically mean a stroke or heart attack is imminent, the findings underscore the intricate link between cardiovascular health and brain function. Factors like long-term high blood pressure, diabetes, smoking, poor sleep, and lack of physical activity can all impair blood vessels, affecting the brain's small vessels and blood flow. This can lead to a noticeable dulling of reaction speed.

The earliest differing item was processing speed, which is the speed of seeing information, understanding, judging, and reacting.

Family members are advised to monitor subtle changes in an elder's daily life, such as slower walking, difficulty with tasks like counting money or reading medicine labels, or delayed responses in conversations. If these changes occur alongside existing conditions like hypertension, high cholesterol, irregular heartbeat, chest tightness, dizziness, or an increase in falls, a medical evaluation is recommended. Dr. Fu stresses that early detection of these subtle signals can help address potential cardiovascular risks before a major event occurs.

Good elderly care is not to regret after a stroke, myocardial infarction, or heart failure occurs, but to start from small daily changes and understand the body's distress signals early.
