What Is Cognitive Function?
Cognitive function refers to the brain’s ability to process information, learn, remember, reason, solve problems, communicate, and make decisions. Healthy cognitive function is essential for completing everyday activities, maintaining independence, and interacting with others.
Cognitive abilities naturally change with age, but significant declines should be evaluated by a healthcare provider.
