Objectives: Cognitive reserve provides evidence in the search for answers regarding the role that lifestyle has in the protection of cognition in old age. Through a structural equations model, different things were analyzed: the relative weight of education, occupational complexity, free time activities and the intelligence quotient in cognitive reserve; and its impact on three cognitive domains: memory, language and executive functions. Design: A trail analysis was executed, using structural equations procedure. Participants: 167 older participants (mean = 76.74 years, standard deviation = 6.8 years). Measurements: Participants were assessed with: Sociodemographic Questionnaire, Occupational Activity Agency Questionnaire, Social Participation Questionnaire and Neuropsychological Evaluation Battery for: memory, language and executive functions. Results: The cognitive reserve factor is well represented by the measures included, with values ​​between.43 and.86, and shows a direct effect on language (β =.52, p
