Sumario:Objective: To identify which components of semantic memory are predictors of cognitive impairment in older adults.Material and Methods: Quantitative and predictive study, conducted on a non-probabilistic sample of 160 older adults in Metropolitan Lima, with an average age of 74.7 years, who were evaluated with the Mini-Mental Status Examination (MMSEA) on the Semantic Memory Evaluation Battery for Adults (EMSEA).Results: 20.7% of the sample presented cognitive impairment. Regarding semantic memory, 23.4% obtained a low level, 49.4% an intermediate level and 27.2% a high level. According to the multivariate model, the factors associated to cognitive impairment were the semantic memory subtests: Picture Naming, Attributes Recognition and Verification of True or False Statements (R2 = 30.8%, p≤.001). These results are reflected with a complementary network analysis, where the centrality analysis indicated that the Verbal Fluency task and Verification of True or False Statements, are the frameworks of greatest interest. Conclusions:The existence of associated factors of semantic memory that better predict cognitive deterioration are Picture Naming, Attributes Recognition and Verification of True or False Statements.
