What is the most reliable screening instrument to assess memory alterations in a patient after surgery?

The Mini-Mental State Examination (MMSE) is widely regarded as a reliable tool for assessing cognitive functions, particularly memory, in patients post-surgery. It comprises various tasks that evaluate different cognitive domains, including orientation, attention, memory, and language skills. Given that memory alterations can significantly impact recovery, the MMSE provides a structured and standardized way to gauge these changes.

Its strength lies in its simplicity and ease of administration, making it accessible in both clinical and non-clinical settings. The tools are well-researched and validated, allowing professionals to track changes over time, which is crucial in a post-surgical context where cognitive recovery may be a concern.

In contrast, other options like the Test of Problem Solving (TOPS-3) focuses more on pragmatic language skills and problem-solving abilities rather than memory specifically. The Cognitive Linguistic Quick Test (CLQT) assesses a broader range of cognitive-linguistic abilities, but it also may not target specific memory functions as directly as the MMSE. The Global Deterioration Scale (GDS) offers insights into the overall cognitive decline but is less focused on specific memory evaluation.

For these reasons, the MMSE stands out as the most reliable screening tool for assessing memory alterations specifically
