An elderly patient scores 18 on the MMSE. What does this score typically indicate?

• A. Severe cognitive impairment
• B. Mild cognitive impairment
• C. Moderate cognitive impairment
• D. Normal cognition

Answer: (C)

A score of 18 on the Mini-Mental State Examination (MMSE) typically indicates moderate cognitive impairment. The MMSE is a widely used tool to assess cognitive function and screen for dementia.

Scores on the MMSE can be categorized to provide insight into the level of cognitive impairment:

• A score of 24-30 indicates normal cognition.

• A score of 18-23 suggests moderate cognitive impairment, as individuals in this range may struggle with more complex cognitive tasks but can still engage in some daily activities.

• A score below 18 indicates severe cognitive impairment, where individuals may have significant difficulties with basic activities of daily living.

Thus, a score of 18 reflects a level of cognitive functioning that is significantly less than normal, but still above the threshold that would signify severe impairment. This level provides essential information when considering care needs and further evaluation for potential dementia or other cognitive disorders.
