ABSTRACTBackground:Cognitive impairment is underrecognized and misdiagnosed among community-dwelling older adults. At present, there is no consensus about which cognitive screening tool represents the “gold standard.” However, one tool that shows promise is the Brief Cognitive Assessment Tool (BCAT), which was originally validated in an assisted living sample and contains a multi-level memory component (e.g. word lists and story recall items) and complex executive functions features (e.g. judgment, set-shifting, and problem-solving).Methods:The present study cross-validated the BCAT in a sample of 75 community-dwelling older adults. Participants completed a short battery of several individually administered cognitive tests, including the BCAT and the Montreal Cognitive Assessment (MoCA). Using a very conservative MoCA cut score of <26, the base rate of cognitive impairment in this sample was 35%.Results:Adequate internal consistency and strong evidence of construct validity were found. A receiver operating characteristic (ROC) curve was calculated from sensitivity and 1-specificity values for the classification of cognitively impaired versus cognitively unimpaired. The area under the ROC curve (AUC) for the BCAT was .90,p< 0.001, 95% CI [0.83, 0.97]. A BCAT cut-score of 45 (scores below 45 suggesting cognitive impairment) resulted in the best balance between sensitivity (0.81) and specificity (0.80).Conclusions:A BCAT cut-score can be used for identifying persons to be referred to appropriate healthcare professionals for more comprehensive cognitive assessment. In addition, guidelines are provided for clinicians to interpret separate BCAT memory and executive dysfunction component scores.

The Relationship

Abstract Introduction Recent studies identified a relationship between gait difficulties and risk of developing dementia, a condition now termed motoric cognitive risk. We interrogated a clinical dataset to determine the relationship between cognitive assessment scores and physical performance scores to identify the strength of association between these two types of measures. Methods Consecutive patients referred to the falls and syncope service and the University of Malaya Medical Centre were recruited. The cognitive function of consenting individuals was assessed using the Montreal Cognitive Assessment (MoCA) and Visual Cognitive Assessment Tool (VCAT). Physical performance was assessed using hand grip strength (HGS), timed-up-and-go (TUG) and functional reach (FR). Results One hundred and forty-seven individuals, mean age (standard deviation,SD)=76.1 (7.8) years, 85 (58%) women were included. The mean (SD) for right and left HGS, FR and TUG scores for the overall population were 19.1 (7.0)kg, 19.0 (12.1)kg, 28.9 (39.7)cm, TUG 19.2 (11.0)s respectively. The mean MoCA and VCAT scores were 21.1 (7.1) and 20.3 (6.3) respectively. Right HGS correlated moderately with MoCA (r=0.367) and VCAT scores (r=0.397). Left HGS had a weak to moderate correlation with MoCA (r=0.281) and VCAT (0.271). FR, however, was not correlated with either MoCA (r=0.073) and VCAT (0.020). TUG scores were moderately negatively correlated with MoCA (-0.3206) but weakly correlated with VCAT (-0.175) Conclusion Our evaluation of the relationship between cognitive scores and physical performance in a falls and syncope clinic setting found that a relationship exists between muscle strength measured with grip strength and composite assessment of gait and balance using the TUG. Dynamic balance measured with functional reach, however, was not associated with cognitive function. Future studies will need to identify the possible mechanisms linking cognitive function with strength and gait in order to establish cognitive function as a modifiable risk factor for falls in older adults.

AbstractObjectives: Impairments of Theory of Mind (ToM) have been repeatedly demonstrated in patients with schizophrenia (SCZ). However, only a handful of studies have explored deficits in affective and cognitive subcomponents of ToM. Thus, this study aims to examine affective and cognitive ToM abilities in SCZ by using a novel, verbal paradigm. Methods: Twenty-four SCZ and 22 healthy comparison subjects (HC) completed a battery of tasks, which consisted of: (i) Brief Cognitive Assessment Tool for Schizophrenia (B-CATS), (ii) three well-established tasks measuring social cognitive abilities, and (iii) original tasks which assess ability to infer cognitive and affective mental states based on everyday verbal social interactions. Results: In line with previous findings, SCZ were outperformed by HC in all tasks. However, the interaction effect of the group and the task showed that cognitive (as opposed to affective) ToM was more profoundly impaired in patients with SCZ. Conclusions: It is proposed that in SCZ group cognitive ToM is more impaired as it involves more effortful reflective processes, while affective ToM, which is more automatic and based on reflexive processes, may differentiate patients from healthy comparison subjects to a lesser extent.
