Aging is associated with cognitive and functional changes that may compromise the autonomy and quality of life of older adults. This study aimed to identify the cognition and functionality of older adults attended at a Teaching Clinic. A longitudinal and quantitative study was conducted with 10 participants aged ≥60 years. The Mini-Mental State Examination (MMSE), the Katz Index, and the Lawton and Brody Scale were applied at two moments: baseline (T0) and after six months of cognitive interventions (T1). Chi-Square and Wilcoxon tests were applied (p<0.05). Ethical approval was obtained under Opinion No. 6,495,658. At the initial assessment, 70% showed preserved cognition and 90% had partial dependence in instrumental activities of daily living (IADL), although all were independent in basic activities. After the intervention period, a slight reduction in the proportion of preserved cognition was observed (60%), without statistical significance (p=0.317). In contrast, there was a significant improvement in autonomy for IADL, with an increase in independence from 10% to 80% (p=0.008). No statistically significant association was found between cognition and functionality. It is concluded that cognitive stimulation, even in the short term, proved effective in promoting functional autonomy, standing out as a relevant strategy in nursing care for the elderly. Studies with larger samples and prolonged follow-up are recommended to deepen the understanding of the effects on cognition
