Objectives: To determine if there is an association between the occurrence of the depressive disorder and neurocognitive disorders in elderly subjects from three Peruvian cities. Materials and methods: This is an analytical cross-sectional study, and a non-randomized sample was taken. Elderly subjects more than 60 years of age from Ucayali, Ica, and Lima were included. Between March and May 2016 the presence of a depressive disorder and cognitive deterioration was assessed using the Yesevage (GDS) and the Pfeiffer scales, respectively. Results: Two hundred and sixty seven elderly subjects were interviewed; 58.4% were male; and the mean age of the whole group was 75 ± 7.6 years old. Approximately one third (36.3%) of all subjects had cognitive deterioration, and 64% had moderate or severe depression. Also, a relationship was found between age and depression (p<0.05), and there was an association between cognitive deterioration and severe depression (prevalence ratio (PR): 2.1; 95% confidence interval: 1.4-3.2); having between 80 to 89 years of age (PR: 1.9; 95% CI: 1.2-3.1), and coming from Ucayali (PR: 1.67; 95% CI: 1.21-2.31). Conclusion: In the assessed patients, depression scores increased with age, and there was a greater likelihood for developing a neurocognitive disorder in those who had severe depression
