title: [Mild cognitive impairment: a prevalence and sociodemographic factors study in the city of Córdoba, Argentina].
abstract: BACKGROUND
  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.
  
  
  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.
  
  
  CONCLUSIONS
  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.
