Which statement accurately describes the distinction between MCI and dementia in terms daily living?

• A. MCI shows cognitive decline that does not yet interfere with most daily activities.
• B. Dementia shows cognitive decline that does not affect daily living.
• C. MCI and dementia are identical in functional impact.
• D. Dementia improves with time and medication.

Answer: (B)

Daily functioning is the key distinction. Mild cognitive impairment means there’s noticeable cognitive change beyond normal aging, but people generally stay independent in daily activities. They may need reminders or more time to complete tasks, but basic self-care and most instrumental activities of daily living remain intact.

Dementia, by contrast, involves cognitive decline that interferes with daily life. This means problems with both basic activities of daily living (like bathing or dressing) and instrumental activities (such as managing finances, medications, transportation, or meal preparation) that require organization and judgment. Because of this impact on independence, dementia typically necessitates increased supervision or assistance.

So the statement that dementia does not affect daily living doesn’t fit the pattern; dementia is defined by impairment in daily functioning, whereas MCI preserves independence in daily activities.
