Abstract

Objective To investigate the difference in the Montreal Cognitive Assessment-Basic(MoCA-B) sub-item scores between patients of different age with mild cognitive impairment(MCI).Methods One hundred and ninety MCI patients were recruited from the outpatients and inpatients of the Department of Neurology and surrounding communities between January 2017 and December 2017. Patients were divided into three groups according to their age: 50-59(n=47), 60-69(n=73) and 70-79(n=70). All the patients were subjected to a survey by means of Mini-Mental State Examination(MMSE)and MoCA-B.Results There was no significant difference between the three groups in gender, levels of education, MMSE or MoCA-B. When each item of MoCA-B was compared between the three groups, verbal fluency test(VFT) and delayed recall were significantly different(P<0.05). Patients under 60 got a little higher scores in VFT than those above 60(0.8±0.5 vs 0.5±0.6), but the difference was not statistically significant. For verbal delayed recall, the scores of the three groups were(1.1±1.0),(0.4±0.8) and(0.5±1.0),respectively. Patients under 60 got higher scores than older ones. The difference was significant between the three groups(P<0.05).Conclusions When interpreting the scores of each item of MoCA-B, we should pay attention to the possible influence of age, especially the verbal delayed recall score.
