Abstract
ABSTRACTSome cognitive dimensions, such as attention, memory and executive functions, may decline with age, while other functions remain intact or even improve due to greater life experience.Objective:to analyze the relationship between cognitive processing, language and verbal fluency among elderly individuals seen by primary healthcare services located in a city in the interior of São Paulo, Brazil.Methods:a cross-sectional study with a quantitative method was conducted. A total of 149 elderly individuals were assessed through previously scheduled interviews. Data collection included a questionnaire on sociodemographic data and the Addenbrooke's Cognitive Examination - Revised (ACE-R). Cognitive processing (P300) was assessed using a device that captures potentials elicited in auditory tasks. Descriptive analysis and Spearman's correlation were performed with the level of significance established at 5%.Results:a negative correlation was found between language and P300 latency, while a positive correlation was found between verbal fluency and P300 amplitude. Comprehension and naming tasks showed a negative correlation with latency. The repetition task revealed a positive correlation with P300 amplitude.Conclusion:although more extensive testing is needed, these findings suggest that language correlates with P300 latency, whereas verbal fluency correlates with P300 amplitude.
Highlights
Some cognitive dimensions, such as attention, memory and executive functions, may decline with age, while other functions remain intact or even improve due to greater life experience
This study was prompted by the question: Are P300 results related to results obtained by the Addenbrooke’s Cognitive Examination – Revised (ACE-R) on the language and verbal fluency domains? For this reason, this study’s objective was to analyze the relationship between cognitive processing, language and verbal fluency of elderly individuals seen by primary healthcare services located in a city in the state of São Paulo, Brazil. This cross-sectional study is based on the assumptions of quantitative research and is part of a larger study called “Primary Health Care Follow-up of Elderly Caregivers” that was conducted by the Health and Aging Research Group at the Federal University of São Carlos (UFSCar), that collected sociodemographic, health, cognitive, psychological and functional data of elderly people registered at the Family Health Units of a city in the interior of São Paulo
The performance of 51 (34.22%) elderly individuals attained the cut-off point on the ACE-R expected for educational level, while 98 elderly individuals (65.78%) scored below the cut-off point on the ACE-R, i.e. lower than expected score for level of education
Summary
Some cognitive dimensions, such as attention, memory and executive functions, may decline with age, while other functions remain intact or even improve due to greater life experience. Objective: to analyze the relationship between cognitive processing, language and verbal fluency among elderly individuals seen by primary healthcare services located in a city in the interior of São Paulo, Brazil. Results: a negative correlation was found between language and P300 latency, while a positive correlation was found between verbal fluency and P300 amplitude. Conclusion: more extensive testing is needed, these findings suggest that language correlates with P300 latency, whereas verbal fluency correlates with P300 amplitude. RELAÇÃO ENTRE PROCESSO COGNITIVO, LINGUAGEM E FLUÊNCIA VERBAL ENTRE IDOSOS INDIVIDUAIS RESUMO. Objetivo: analisar a relação entre processamento cognitivo, linguagem e fluência verbal em idosos atendidos em serviços de atenção básica localizados em um município do interior de São Paulo, Brasil. Resultados: foi encontrada correlação negativa entre a linguagem e a latência do P300 e uma correlação positiva entre a fluência verbal e a amplitude do P300. This study was conducted at the Federal University of São Carlos (UFSCar), Graduate Program in Nursing, São Carlos, SP, Brazil
