Cognitive decline

Topic

Heard on podcasts recently

Cognitive decline, often referred to as cognitive impairment, is a gradual or sudden reduction in cognitive abilities such as memory, attention, language, and problem-solving. It can range from mild changes associated with normal aging to more severe deficits caused by neurodegenerative conditions like dementia and Alzheimer's disease. This impairment acts as a barrier to normal mental processes, affecting how an individual gains, processes, and retains knowledge.
