Cognitive aging is a research area that focuses on understanding how cognitive abilities change as people grow older. This includes studying the effects of aging on memory, attention, processing speed, decision-making, and other cognitive functions. Researchers in this area seek to identify the factors that contribute to cognitive decline in older adults, as well as potential strategies for maintaining or improving cognitive function in later life. Cognitive aging research is important for understanding the impact of aging on cognitive abilities and developing interventions to support healthy aging and prevent cognitive decline.
