title: Prevalence of mild cognitive impairment and its subtypes in the Mexican population.
abstract: OBJECTIVE
  To estimate the prevalence of mild cognitive impairment (MCI) and its subtypes, taking into account education and health status.
  
  
  METHODS
  This is the first report of our Study on Aging and Dementia in Mexico. This study included 2,944 elderly individuals 60 years old or more with in-home assessment for cognitive impairment. The prevalence of MCI was based on Petersen criteria. MCI was classified as amnestic of single domain (a-MCI-s) or multiple domain (a-MCI-md) or nonamnestic of single domain (na-MCI-s) or multiple domain (na-MCI-md). In addition to a battery of neuropsychological measures, a self-report depression measure and a medical history including history of stroke, heart disease and other health conditions were recorded.
  
  
  RESULTS
  The global estimated prevalence of MCI in the Mexican population was 6.45%. Of these subjects, 2.41% met criteria for a-MCI-s, 2.56% for a-MCI-md, 1.18% for na-MCI-s and 0.30% for na-MCl-md. Women showed a higher prevalence of MCI than men (63.7 vs. 36.3%, respectively). The analysis showed that heart disease [odds ratio (OR) 1.5], stroke (OR 1.2) and depression (OR 2.1) were associated with an increased risk of MCI.
  
  
  CONCLUSIONS
  The prevalence of MCI in Mexico is similar to that in other countries. The results suggest that stroke, heart disease and depression may have an important role in the etiology of MCI.
