Living with heart failure is physically demanding, but it can also take a toll on the brain. A large review of data from over 8,000 older adults found that about 32% of those with heart failure experience cognitive frailty. This condition involves a decline in mental abilities that makes daily tasks harder to manage.
The study highlights how certain factors change these risks. For example, the rate of cognitive frailty was higher in women (37%) and among those with more severe symptoms. It was also notably higher in people with chronic obstructive pulmonary disease (46%). These findings suggest that heart health and lung health are closely tied to brain health.
While the study is based on observational data, it did find some clear patterns. Depression was linked to a higher risk of cognitive frailty, while regular exercise and intellectual activity were linked to lower risks. Because this research is based on observations rather than controlled trials, we cannot say for certain what causes these links, but they point toward the importance of early screening.
