What is dementia?

What is dementia?

• A. Rapidly progressive loss of memory that is reversible
• B. Slowly progressive decline in mental abilities, including memory, thinking, and judgment, often with personality changes
• C. A temporary confusion due to dehydration
• D. A normal part of aging with no effect on function

Answer: (B)

Dementia is a chronic, progressive decline in cognitive function that affects multiple areas—memory, thinking, and judgment—and often leads to changes in personality or behavior, eventually interfering with daily activities. This gradual loss of abilities distinguishes it from normal aging, where forgetfulness may occur but daily functioning remains intact. It also differs from delirium, which is an acute, fluctuating confusion typically caused by an underlying illness or reversible factors like dehydration or medication effects. The description that best fits dementia describes this slow, persistent deterioration in cognitive skills with impact on daily life, rather than something that is reversible or temporary or something that’s simply a normal part of aging.
