New research reveals that heart failure is associated with declines in cognitive functions such as memory, attention, and planning. This link is thought to result from reduced blood flow to the brain, inflammation, and related conditions like diabetes.
Heart failure, a condition where the heart cannot pump enough blood to meet the body’s needs, affects nearly 7 million Americans. While it mainly causes symptoms like fatigue and breathlessness, recent findings highlight its impact on brain health as well.
Researchers analyzed data from nearly 30,000 adults over several decades. They found that people diagnosed with heart failure showed a decline in overall cognitive ability, especially in executive function and memory, around the time of diagnosis.
Experts believe this cognitive decline may be caused by several factors. The weakened heart delivers less oxygen-rich blood to the brain. Additionally, inflammation triggered by heart failure and coexisting diseases like diabetes and high blood pressure may damage brain function over time.
The study’s lead author, Dr. Supriya Shore, emphasizes that cognitive difficulties make managing heart failure more challenging since patients need strong mental skills to handle complex treatment routines. Caregivers also bear an increased burden as the disease progresses.
While memory issues may lessen over time, other thinking skills continue to deteriorate, underscoring the importance of early recognition and support for brain health in people with heart failure.
The findings highlight the critical connection between heart and brain health, urging both patients and healthcare providers to address cognitive concerns alongside cardiac care.
