This study suggests unexplained cognitive changes in older adults may warrant a closer look at heart health.
In older adults, thinking skills started declining 3 to 8 years before they had a major cardiovascular event like a stroke or heart failure. The drops showed up in memory, processing speed, and verbal fluency compared to people who stayed healthy. This hints that heart disease and brain aging share deep roots, and subtle cognitive changes might be an early warning sign.
