Cognitive function

cognitive function

Cognitive function is the set of mental abilities your brain uses to think, learn, remember, pay attention, solve problems, and use language. It includes things like short-term and long-term memory, the ability to focus, how quickly you process information, and planning or decision-making skills. These abilities work together every day when you cook, drive, hold a conversation, or manage money. Cognitive function can change over time because of normal aging, illnesses, medications, stress, sleep quality, and lifestyle. Small swings in how well your brain works are common, but large or sudden changes can signal a health problem. Keeping cognitive function healthy matters because it affects independence, safety, work performance, and quality of life. Simple steps like regular physical activity, enough sleep, balanced nutrition, mental stimulation, and social contact can help preserve these skills. Managing chronic conditions such as high blood pressure, diabetes, and depression also supports brain abilities. If you or someone close to you notices noticeable decline or sudden trouble with memory or thinking, it’s smart to talk with a healthcare professional for evaluation and guidance.
