What MoCA score indicates severe cognitive impairment?

• A. 18-25/30
• B. 24-30/30
• C. <18/30
• D. 10-17/30

Answer: (C)

The MoCA is a 30-point screening tool where lower scores mean greater cognitive impairment. Normal performance is typically 26 or higher. A score below 18 indicates severe cognitive impairment, reflecting substantial deficits across multiple domains such as memory, attention, language, and executive function. This level often corresponds to more advanced dementia and signals the need for a thorough evaluation and further management. Scores in the 18–25 range suggest mild impairment, while 26–30 is considered normal, so the threshold for severe impairment is the score being under 18.
