49/100

✓ Peer-reviewed alzhub usefulness score 49 out of 100. Cognitive tests and assessment

Topic: Risk, prevention and care in population studies

Plain-language summary

Background To examine the discriminant validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in detecting patients with cognitive impairment at higher risk for dementia at a memory clinic setting. Methods Memory clinic patients were administered the MoCA, MMSE, and a comprehensive formal neuropsychological battery. Mild cognitive impairment (MCI) subtypes were dichotomized into two groups: single domain-MCI (sd-MCI) and multiple domain-MCI (md-MCI).

What this study adds

Evidence grade: Low

The record lists 36 participants. This study compared the Montreal Cognitive Assessment and the Mini-Mental State Examination in memory clinic patients to see which better detects people at higher risk of dementia. Reported effect size: 59.1%; 26.5%; 14.3%.

Taken from this record’s own fields, not from reading the paper. The grade is assigned from the abstract’s wording; what that means.

Built from the record alzhub holds for this paper, not looked up. Volume, issue and page numbers are not held in the record. The record names 7 authors; APA and Vancouver show the first six, BibTeX and the downloads carry all of them. Check the citation against the original before you use it.

How to read this study

Design: our record does not state a study design, so check the methods section of the original before weighing the result.
Size: the record lists 36 participants. Ask whether that is enough for the question, and who they were.
Effect: the record reports “59.1%; 26.5%; 14.3%”. A statistically significant result can still be small in daily life.

What the evidence grade means here

This page is graded low. alzhub.org assigns the grade automatically from keywords in the abstract, not from reading the paper. Low means the abstract matched neither pattern. It is the default label, and it does not mean the work is poor; many sound lab and imaging papers land here. It can add at most 5 of the 100 points in the study score, and it is a label about design, not a verdict on whether the findings are true.

Key findings

Methods Memory clinic patients were administered the MoCA, MMSE, and a comprehensive formal neuropsychological battery.
Mild cognitive impairment (MCI) subtypes were dichotomized into two groups: single domain-MCI (sd-MCI) and multiple domain-MCI (md-MCI).
Area under the receiver operating characteristic curve (ROC) analysis was used to compare the discriminatory ability of the MoCA and the MMSE.
Results Two hundred thirty patients were recruited, of which 136 (59.1%) were diagnosed with dementia, 61 (26.5%) with MCI, and 33 (14.3%) with no cognitive impairment (NCI).

Why it matters

This study compared the Montreal Cognitive Assessment and the Mini-Mental State Examination in memory clinic patients to see which better detects people at higher risk of dementia. It is about cognitive testing and does not test any treatment, so it says nothing about curing or preventing Alzheimer's disease.
