Dementia is best described as:

• A. A temporary decline in memory due to stress.
• B. An umbrella term for conditions causing memory loss and other thinking problems that worsen over time.
• C. A treatable disorder with sudden onset and full recovery.
• D. A disease limited to motor function impairment.

Answer: (B)

Dementia is a broad, progressive set of conditions in which memory loss and other thinking problems steadily worsen over time. It’s an umbrella term that includes various causes (like Alzheimer’s disease, vascular dementia, Lewy body dementia, and others) where cognitive decline interferes with daily activities and independence. This differentiates it from temporary or reversible issues: a short-term decline due to stress or anxiety, or delirium, does not follow the same gradual, ongoing course. It also isn’t limited to motor problems; while some forms may have motor or behavioral symptoms, the defining feature is the persistent, progressive cognitive decline rather than a purely motor disorder.
