- Normative data for the Brief Cognitive Screening Battery stratified by age and education(2017) YASSUDA, Mônica Sanches; SILVA, Henrique Salmazo da; LIMA-SILVA, Thais Bento; CACHIONI, Meire; FALCÃO, Deusivania Vieira da Silva; LOPES, Andrea; BATISTONI, Samila Sathler Tavares; NERI, Anita LiberalessoABSTRACT Introduction: Diagnosing neurocognitive disorders is challenging in low-educated individuals. Objective: To report normative data for the Brief Cognitive Screening Battery (BCSB) and to assess the association of age and education with performance on the BCSB in 240 community-dwelling elderly from Ermelino Matarazzo, São Paulo city. Methods: The inclusion criteria were scoring above the education-adjusted cut-off points on the Mini-Mental State Examination (MMSE) and below six points on the Geriatric Depression Scale (GDS). Results: Age was associated with performance on the Naming, Incidental Memory, Verbal Fluency, Clock Drawing Test, Delayed Recall and Recognition subtests. Education was associated with performance on Naming, Recognition, Verbal Fluency and the Clock Drawing Test. Conclusion: The normative values reported are relevant for diagnosing neurocognitive disorders in low-educated elderly.
- Recalling feature bindings differentiates Alzheimer's disease from frontotemporal dementia(2017) CECCHINI, Mario Amore; YASSUDA, Monica Sanches; BAHIA, Valeria Santoro; SOUZA, Leonardo Cruz de; GUIMARAES, Henrique Cerqueira; CARAMELLI, Paulo; CARTHERY-GOULART, Maria Teresa; PATROCINIO, Flavia; FOSS, Maria Paula; TUMAS, Vitor; LIMA-SILVA, Thais Bento; BRUCKI, Sonia Maria Dozzi; NITRINI, Ricardo; SALA, Sergio Della; PARRA, Mario A.It has been challenging to identify clinical cognitive markers that can differentiate patients with Alzheimer's disease (AD) from those with behavioral variant frontotemporal dementia (bvFTD). The short-term memory binding (STMB) test assesses the ability to integrate colors and shapes into unified representations and to hold them temporarily during online performance. The objective of this study is to investigate whether free recall deficits during short-term memory binding (STMB) test can differentiate patients with AD from those with bvFTD and controls. Participants were 32 cognitively intact adults, 35 individuals with AD and 18 with bvFTD. All patients were in the mild dementia stage. Receiver-operating characteristic (ROC) analyses were used to examine the diagnostic accuracy of the STMB. The results showed that AD patients performed significantly worse than controls and bvFTD patients in the STMB test, while the latter groups showed equivalent performance. The bound condition of the STMB test showed an AUC of 0.853, with 84.4% of sensitivity and 80% of specificity to discriminate AD from controls and an AUC of 0.794, with 72.2% of sensitivity and 80% of specificity to differentiate AD from bvFTD. Binding deficits seem specific to AD. The free recall version of the STMB test can be used for clinical purposes and may aid in the differential diagnosis of AD. Findings support the view that the STMB may be a suitable cognitive marker for AD.
- Actively station: Effects on global cognition of mature adults and healthy elderly program using eletronic games(2017) ORDONEZ, Tiago Nascimento; BORGES, Felipe; KANASHIRO, Camila Sato; SANTOS, Carolina Carneiro das Neves; HORA, Samara Santos; LIMA-SILVA, Thais BentoABSTRACT Studies show that aging is accompanied by decline in cognitive functions but also indicate that interventions, such as training on electronic games, can enhance performance and promote maintenance of cognitive abilities in healthy older adults. Objective: To investigate the effects of an electronic game program, called Actively Station, on the performance of global cognition of adults aged over 50 years. Methods: 124 mature and elderly adults enrolled in the ""Actively Station"" cognitive stimulation program of São Caetano do Sul City, in the State of São Paulo, participated in training for learning of electronic games. Participants were divided into two groups: training group (TG) n=102 and control group (CG) n=22. Protocol: a sociodemographic questionnaire, the Mini-Mental State Examination (MMSE), the Addenbrooke's Cognitive Examination Revised (ACE-R), the Memory Complaint Questionnaire (MAC-Q), the scale of frequency of forgetfulness, the Geriatric Depression Scale (GDS-15), the Geriatric Anxiety Inventory (GAI), the Global Satisfaction with Life Scale, and two scales on learning in the training. Results: The cognitive performance of the TG improved significantly after the program, particularly in the domains of language and memory, and there was a decrease on the anxiety index and frequency of memory complaints, when compared to the CG. Conclusion: These findings suggest that the acquisition of new knowledge and the use of new stimuli, such as electronic games, can promote improvements in cognition and mood and reduce the frequency of memory complaints.
