What impact does aging have on cognitive function?

• A. A decline in intelligence
• B. An increase in cognitive abilities
• C. No change in cognitive function
• D. A decrease in cognitive function

Answer: (D)

Aging is associated with a variety of changes in cognitive function, and research indicates that many cognitive abilities tend to decline with age. This decline is particularly noticeable in areas such as processing speed, working memory, and executive function, which can affect an older adult's ability to think quickly and manage multiple tasks effectively. While some cognitive abilities, such as vocabulary and general knowledge, may remain stable or even improve due to accumulated life experiences, the overall trend is a decrease in cognitive function in certain domains. This decrease can be attributed to various factors, including neurological changes such as reduced synaptic plasticity, alterations in neurotransmitter systems, and brain structural changes, such as atrophy in key areas associated with cognitive processing. These changes can impact the efficiency and effectiveness of cognitive processes over time, leading to the conclusion that aging generally correlates with a decrease in certain cognitive functions.
