A progressive brain disorder that destroys memory and thinking skills is called what?

• A. Alzheimer's disease
• B. Mild cognitive impairment
• C. Vascular dementia
• D. Frontotemporal dementia

Answer: (A)

Alzheimer's disease is a progressive brain disorder that destroys memory and thinking skills. It is the most common cause of dementia and typically starts with subtle short-term memory difficulties, then gradually affects language, problem solving, and the ability to perform daily activities. The decline is gradual and irreversible, reflecting neurodegenerative changes in the brain. Treatments can modestly help symptoms or slow progression for some people, and planning for care becomes important as the disease advances. Other conditions can cause cognitive changes, but they differ in pattern: mild cognitive impairment involves noticeable decline without major daily-life impairment; vascular dementia follows strokes or vascular problems and often shows a stepwise decline; frontotemporal dementia affects behavior and language early and may impair memory later.
