[Mild cognitive impairment: a prevalence and sociodemographic factors study in the city of Córdoba, Argentina]. / Deterioro cognitivo leve: estudio de prevalencia y factores sociodemográficos en la ciudad de Córdoba, Argentina.

INTRODUCTION: The increase in life expectancy and the significant growth in the population of the elderly have generated an interest in secondary prevention of different diseases, especially from the age of 50. In Argentina, those over 65 represent 10% of the total population, what makes important to research into their mental health. A trans-sectional descriptive study has been carried out in four neuropsychology services in the city of Cordoba, within the framework of a campaign assessing memory for people over 50. SUBJECTS AND METHODS: In three months, 418 volunteers took part, with an average age of 64.24 years and 12.76 years of instruction, mostly belonging to a urban environment (80%). They were administered Folstein's Minimental State, neuropsychological tests and behavioral measures in two work sessions. RESULTS: The majority was found to have normal performances (75.6%, n = 316) at both behavioral and neuropsychological levels. A lower percentage was found at the borders of normality (8.6%, n = 36). 9.1% (n = 38) of those studied were found to have an amnesiac type of mild cognitive impairment, and 4.5% (n = 19) a multidomain type of deterioration. In sum, about 13.6% of people have a greater chance of developing dementia in coming years. CONCLUSION: The socio-demographic variables that most influence cognitive state appear to be the female gender, age higher than 65 years, lower levels of instruction, fewer children and fewer siblings.

Introducción. El aumento de la expectativa de vida y un crecimiento significativo de la población de adultos mayores ha generado un interés por la prevención secundaria de diversas enfermedades, especialmente a partir de los 50 años. En Argentina, sólo los mayores de 65 años representan el 10% de la población total, por lo que resulta importante investigar sobre su estado mental. En este sentido, se realizó un estudio descriptivo transeccional en cuatro servicios de neuropsicología de la ciudad de Córdoba, en el marco de una campaña de evaluación de la memoria destinada a personas mayores de 50 años. Sujetos y métodos. En un período de tres meses, participaron 418 voluntarios con un promedio de edad de 64,24 años y de instrucción de 12,76 años, pertenecientes en su mayoría al medio urbano (80%). Se les administró el test minimental de Folstein, pruebas neuropsicológicas y medidas conductuales en dos sesiones de trabajo. Resultados. Se encontró que la mayoría (75,6%, n = 316) tuvo un rendimiento normal tanto neuropsicológico como conductual. En el límite de lo normal se halló un porcentaje menor (8,6%, n = 36). Se detectó un 9,1% (n = 38) con deterioro cognitivo leve de tipo amnésico y un 4,5% (n = 19) con deterioro leve de tipo multidominio, es decir, un 13,6% de personas con una mayor probabilidad de desarrollar demencia en los próximos años. Conclusión. El género femenino, la edad superior a 65 años, el menor nivel de instrucción y el número de hijos parecen ser las variables sociodemográficas que más influyen en el estado cognitivo
