Which term denotes a diffuse loss of memory and cognitive function commonly seen in aging?

• A. Dementia
• B. Pulse Oximetry
• C. Bacteremia
• D. Angina

Answer: (A)

Dementia describes a broad, diffuse decline in memory and thinking that interferes with daily life. It isn’t just normal aging; normal aging may bring occasional forgetfulness, but memory and other cognitive abilities stay largely intact and daily tasks remain doable. In dementia, multiple areas—memory, language, problem-solving, and planning—are affected, and the decline tends to worsen over time. The other terms aren’t about cognitive decline: pulse oximetry measures blood oxygen levels, bacteremia is bacteria in the bloodstream, and angina is chest pain from heart-related blood flow problems.
