ABSTRACT

The COVID-19 social isolation period entailed changes in daily habits and routines, testing the adjustment abilities of the population to address unusual situations. Given that the activities of daily living require a normally functioning cognitive system, the study of cognitive-functional interaction under social isolation is relevant. The object of this work was to obtain information on the cognitive-functional impact of social isolation, analyze the changes induced in daily routines and habits, and assess the cognitive adjustment of the adult population to the isolation requirements. We carried out an online adult population survey, that combined multiple choice or binary questions following a Likert ordinal scale, performing a percentage analysis as well as a principal component analysis of the results. We surveyed 1095 subjects, 68% of which were residents of the Buenos Aires Metropolitan Area (AMBA), of an average age of 52.7 ± 12.8 years, and 15.6 ± 2.2 years of education. All age groups reported attention and memory impairment, more significant in lower age groups and women. The principal component analysis showed an associated correlation of the functional challenge brought about by social isolation on the executive system, with the negative impact on cognitive functions such as attention and memory. Social isolation significantly impacted on the attentional, mnesic and executive cognitive systems, ratifying the role of cognitive abilities in the generation of means and strategies to overcome unusual situations, and highlighting the importance of cognitive-functional interaction.


El período de aislamiento social por COVID-19 generó cambios en los hábitos y rutinas, poniendo a prueba capacidades adaptativas para resolver situaciones infrecuentes. Dado que el sistema cognitivo es el sustrato de las actividades funcionales cotidianas, nuestro objetivo fue conocer el impacto cognitivofuncional del aislamiento, obtener información acerca de los cambios de hábitos y rutinas diarias y evaluar la modalidad de adaptación de la población adulta a la cuarentena. En el marco del Instituto de Salud Pública y Medicina Preventiva de la UBA, realizamos una encuesta online donde se incluyeron preguntas con respuesta de elección según escala ordinal Likert, de tipo binario y de elección múltiple. Se realizó un análisis porcentual de los resultados y un análisis de componentes principales. Encuestamos 1095 sujetos, el 68% fueron residentes en el Área metropolitana de Buenos Aires, edad 52.7 ± 12.8 años y 15.6 ± 2.2 años de instrucción. Todos los grupos de edad refirieron empeoramiento de la atención y memoria, siendo más significativo en las franjas de menor edad y en el género femenino. El análisis de componentes principales mostró una correlación asociada al efecto negativo de factores cognitivos previos como la memoria y la atención con la dificultad durante la cuarentena en el dominio ejecutivo. El aislamiento social impactó en el sistema atencional, mnésico y de funciones ejecutivas. Resultó corroborado el importante rol de las capacidades cognitivas en la generación de recursos y la aplicación de estrategias para adaptarse a situaciones poco habituales, poniendo de manifiesto la interacción cognitivo-funcional.

ABSTRACT

BACKGROUND: The Memory Impairment Screen (MIS-A) is a validated test to detect Alzheimer's Disease (AD) and other dementias. We have modified this test to suit a Spanish speaking population and added a new component, delayed recall (MIS-D). OBJECTIVES: 1) To test a Spanish version of MIS-A and MIS-D. 2) To assess the discriminative validity of MIS-D as a screening tool for the amnestic variant of Mild Cognitive Impairment (aMCI). METHODS: A case-control study of a cohort of 739 aged 65 years old and over, of whom 436 were healthy controls and 303 had a diagnosis of aMCI. The MCI group was patients from the Geriatric Unit for the Elderly at the Italian Hospital of Buenos Aires staffed by geriatricians. MEASUREMENTS: ANOVA test and test t de Student mean comparison. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NVP) were estimated for MIS-D and MIS-A. RESULTS: Normative values for MIS-A and MIS-D were obtained from the control population. Both age and education significantly affected these values (p<0.0001). The cut-off for MIS-A should be 7.5 and for MIS-D, 5.5. Comparison between control population and aMCI population using ROC curve gave a result of 5.5 in MIS-D, with 97% specificity and 76% sensitivity. CONCLUSION: MIS-D was positively predictive of Amci. An extension of the sample in other health care contexts would enable us to verify its clinical validity for other populations.
