dc.description.abstractWe aimed to evaluate whether the performance of the mini-mental state examination

(MMSE) could identify risky mild cognitive impairment (MCI). We recruited 122

amnestic MCI-single domain (ASM), 303 amnestic MCI-multiple domains (AMM), and 94

non-amnestic MCI (NAM). Two-step cluster and linear discriminant analyses were

used for identifying the clusters of the MMSE with age and education, as well as

establishing prediction models for each cluster. Conversion into dementia was

compared among clusters. Cluster analyses revealed the following three: cluster 1

= 205 AMM (100 %); cluster 2 = 61 NAM (33.3 %) and 122 ASM (66.7 %); and cluster

3 = 33 NAM (25.2 %) and 98 AMM (74.8 %). Cluster 3 showed a significantly lower

ability with regards to orientation to time and place, registration of three

words, attention/calculation, language, and copying interlocking pentagons, than

clusters 1 and 2. However, for delayed recall, cluster 1 was significantly more

impaired than cluster 2. Patients in the cluster 1 showed the most common

conversion into dementia [odds ratio (OR) = 2.940 vs. cluster 2, OR = 2.271 vs.

cluster 3]. This study showed that clustering by performance in MMSE could help

define groups at higher risk for conversion to dementia. Therefore, MMSE can be

considered as a promising screening tool including subtyping for MCI when

detailed neuropsychological tests are not feasible.
