“…Combined VFT scores (NC group, 36.2 B 7.3; AD subjects, 20.7 B 7.8) differed from a related previous study (non-demented controls, 29.7 B 8.2; demented subjects, 14.0 B 7.9) [28]. Such differences were related to differences in the test administration procedure.…”

Introduction: The applicability of category verbal fluency test (VFT) as a screening test for Alzheimer’s disease (AD) in the Chinese population was studied. Methods: VFTs with categories of ‘animal’, ‘fruit’ and ‘vegetable’ were administrated to 72 subjects with AD and 81 aged-matched, community-dwelling, non-demented elderly (NC) in Hong Kong. Results: A significant difference in VFT scores between NC and AD groups was found (t-test, p < 0.05). CMMSE scores were significantly correlated with VFT performances in both subject groups. The correlation of combined VFT scores with age and educational level was significant only in the NC group (Pearson correlation, p < 0.05). At a cut-off score of 24/25, the sensitivity and specificity of the VFT in screening of dementia were 86.8 and 93.4% for subjects with no formal education. For literate subjects, an optimal cut-off score of 31/32 was identified across different educational levels. Conclusion: Although VFT performance was influenced by demographic factors like age and education, cognitive function was the most determining factor. With easy administration and satisfactory sensitivity and specificity, VFT is a useful and quick clinical screening test for AD in Chinese elderly.

Background: telomere attrition has been associated with an increased risk of different age-related diseases and is widely accepted as a marker of cellular ageing. On the other hand, it is well known that cognitive function declines with age. The telomere length may therefore act as a marker for the pathway associated with cognitive function. Methods: we examined telomere length and cognitive functions in a community-dwelling Chinese male population aged 65 years and above living in Hong Kong. The telomere length was measured by quantitative real-time PCR in 976 men. Cognitive function was assessed by Chinese (Cantonese) version of Mini-Mental State Exam and Community Screening Interview for Dementia. Results: our result showed there was a significant association between telomere length, delayed recall (P = 0.007) and category verbal fluency (P = 0.048). These associations remained significant after adjustment for age and education. Further analysis using a cut-off score for MMSE, three-item recall and word list generation tests suggested that the telomere length was positively correlated with performance in these areas (P = 0.015). Conclusion: the findings support the association of telomere length and cognitive function and suggested that the telomere length may serve as a biological marker for cognitive decline.

“…However, the characteristics of the CVFT in Chinese subjects with AD have been examined [9,10] , and it has been found that performance in the CVFT is significantly associated with age and educational level in cognitively intact elderly people. In subjects with AD, CVFT performance is associated with cognitive functioning and is a sensitive test for the screening of dementia.…”

Background: Subjective memory complaints in subjects with mild cognitive impairment may represent a genuine decline in episodic memory. This paper evaluates the neuropsychological correlates of the semantic fluency test in subjects with questionable dementia (QD). Methods: A total of 331 Chinese subjects (118 normal controls, NC, 150 with QD and 63 with mild Alzheimer’s disease, AD) were assessed with the Category Verbal Fluency Test (CVFT), the AD Assessment Scale – cognitive subscale (ADAS-Cog), and digit and verbal span tests. CVFT performance was evaluated in each Clinical Dementia Rating (CDR) group. The total number of exemplars, the subcategory and the category size generated were evaluated. Neuropsychological correlates of CVFT scores were computed. Results: Significant differences in CVFT performance were found between the different CDR groups. The subjects with QD had intermediate scores compared to the NC and AD subjects (1-way ANOVA, p < 0.001, post-hoc Bonferroni comparisons). In NC the CVFT scores were significantly associated with ADAS-Cog total, and immediate and delayed recall scores (partial correlations controlled for age and education, p < 0.005). In the QD group the CVFT scores were correlated with ADAS-Cog total, and immediate recall and object naming scores (partial correlation controlled for age and education, p < 0.005). Regression analysis revealed that age and delayed recall were significant predictors of CVFT performance in NCs. In the QD group, age, ADAS-Cog immediate recall and object naming scores predicted the CVFT performance. Conclusions: The CVFT was impaired in the subjects with QD. Apart from episodic memory, semantic memory deficits also occur early in AD. The different cognitive predictors of CVFT scores in the NC and QD groups suggest that the test is associated with specific psychological functions at different stages of cognitive impairment.
