Which term represents memory impairment?

• A. Dendrites
• B. Dementia
• C. Dental
• D. Dentist

Answer: (B)

Memory impairment refers to trouble remembering information, events, or tasks. When this difficulty is persistent and severe enough to interfere with daily life, it’s described as dementia. Dementia is a broad set of brain disorders marked by progressive memory loss plus other cognitive changes like language and problem-solving difficulties. The other terms don’t describe memory impairment: dendrites are parts of neurons that receive signals, dental relates to teeth, and a dentist is a professional who cares for teeth. So, dementia is the term that represents memory impairment.
