Symptom 8: Confusion or Impaired Thinking: The Cognitive Impact of CHF
Congestive heart failure (CHF), despite being primarily a physical ailment, can have surprising cognitive manifestations. One such manifestation is the sudden onset of confusion or impaired thinking. These cognitive disruptions are noteworthy symptoms that can signal CHF and should be given proper attention.
The heart, with its vital role in pumping oxygen-rich blood throughout the body, supports not only physical activity but also cognitive functioning. In a CHF scenario, however, a weakened heart’s diminished blood-pumping capacity can disrupt this essential supply to the brain.
With the reduced supply of oxygenated blood to the brain due to a failing heart, cognitive functions can become impaired. This can result in episodes of confusion, memory loss, or a generally slow cognitive response. Individuals with CHF might find themselves struggling with tasks that demand attention or mental agility, indicating a possible change in their cognitive health.
Along with confusion, impaired decision-making is another cognitive symptom that CHF patients might experience. This could range from struggling to follow a conversation to difficulty in making choices that were once routine. A once-clear mind might now seem enveloped in a thick fog, making thought processes slow and labored. (8)
