According to the material, what MMSE score range is described as severe impairment?

• A. 24-30
• B. 18-23
• C. 17 and less
• D. 0-10

Answer: (A)

The main idea here is how MMSE scores map onto levels of cognitive impairment. In the material, the range described as severe impairment is 24–30. Since the MMSE is scored 0 to 30 with higher scores indicating better function, this labeling suggests a different schema than the standard one, where higher numbers mean less impairment. Typically, 24–30 is considered normal, 18–23 mild impairment, and 0–17 severe impairment. So, in most settings, severe impairment would be associated with the lower end of the scale, while 24–30 denotes intact cognition. Be aware of the framing in your specific course material, but know the conventional interpretation for clinical practice.
