AB  - BACKGROUND: Research suggests a significant association between increasing age 
      and memory impairments. Nevertheless, for some individuals, memory performance 
      stays within or above the normative values of younger subjects. This is known as 
      successful memory aging and is associated with specific neurophysiological 
      features and psychological and lifestyle-related variables. To date, little is 
      known about the association between successful memory aging and intrinsic 
      capacity (IC) defined as "the composite of all the physical and mental (including 
      psychosocial) capacities that an individual can draw on at any point in time" and 
      resilience. Hence, the aim of this study was to determine if longitudinal 
      associations between IC and successful memory aging and resilience exist and to 
      find differences in cognitive performance between Mexican older adults with 
      successful memory aging, older adults with average memory, and older adults with 
      memory impairment. METHODS: Longitudinal data from 590 individuals from the third 
      wave (2012) and the Mex-Cog subsample (2016) of the Mexican Health and Aging 
      Study was analysed. Subjects were classified into 3 groups: (1) older adults with 
      successful memory aging (SUMA), (2) older adults with average memory (AVMA), and 
      (3) older adults with memory impairment (IMA). Cognitive domains of orientation, 
      language, attention, constructional praxis, and executive function were 
      evaluated. IC and resilience were measured using items from the MHAS battery. 
      Analysis of variance and multinomial logistic regressions were used to find 
      differences in IC and resilience across the memory aging groups. RESULTS: ANOVAs 
      showed significant differences across the three cognitive performance groups in 
      all cognitive domains. Multinomial logistic regression analyses revealed that 
      respondents with higher scores in the psychological and cognitive domains of IC 
      at baseline were more likely to have successful memory aging in the subsequent 
      wave of the study. More resilient subjects in 2012 were not more likely to become 
      a SUMA in 2016. However, this could be a result of the way resilience was 
      measured. CONCLUSION: Our main findings suggest that intrinsic capacity could be 
      used as a predictor of successful memory aging specifically in the psychological 
      and the cognitive domains. More longitudinal studies are needed to further 
      examine these associations.
