Symptom 12: Decreased Alertness: The Cognitive Consequence of CHF
Decreased alertness is another cognitive symptom that can occur in individuals with CHF. Much like confusion or impaired thinking, this symptom often stems from reduced blood flow to the brain, which can lead to various cognitive changes.
When experiencing decreased alertness, a person with CHF might find that they’re not as sharp as they once were. Tasks that require attention and focus might become surprisingly challenging. They may also feel drowsy or fatigued throughout the day, finding it difficult to stay alert and engaged.
In severe cases, decreased alertness can lead to alarming situations such as fainting or even a loss of consciousness. These instances demand immediate medical attention as they could be signs of a severe decline in cognitive function, indicating that the brain is not receiving adequate blood supply.
Changes in alertness can significantly impact daily life, hampering the ability to work, drive, or carry out routine activities. It can also increase the risk of falls and other accidents, posing a substantial threat to the individual’s overall well-being and safety.(12)
