Which statement about MMSE usage is correct?

• A. The MMSE can be used as the sole criterion for diagnosing dementia.
• B. The MMSE is not used in clinical practice.
• C. The MMSE can screen for dementia and delirium and monitor cognitive changes over time, but cannot be used as the sole criterion for diagnosing dementia.
• D. The MMSE measures sleep patterns.

Answer: (C)

The main idea is that the MMSE is a quick screening and monitoring tool for cognitive function. It helps detect cognitive problems consistent with dementia and can be used to follow how cognition changes over time with serial testing. However, a low score or change over time does not by itself establish a dementia diagnosis; dementia requires a broader evaluation that includes history, functional assessment, and other investigations. While the MMSE can raise concern for cognitive disturbance that may be present in delirium, it is not a primary diagnostic tool for delirium and should be used alongside delirium-specific assessments. It does not measure sleep patterns. Therefore, using the MMSE to screen for dementia and monitor changes over time, while relying on additional information to make a diagnosis, is the best approach.
