| Summary: | Memory and mental processing speed are impaired in older adults who have mild cognitive impairment (MCI). Physical and cognitive stimulation can generate positive results in MCI. There are also differences in the intragroup analyzes e impact on memory performance, mental processing speed and brain activity pattern of elderly people with and without MCI submitted to physical and cognitive stimuli. Twenty-eight elderly people participated in the study, which were evaluated: short-term memory and mental processing speed were assessed, as well as the assessing of alpha and beta waves in regions affected by MCI.: Statistically significant differences were found in the following indicators: in working memory, between G1 and G3 (% = -30.0%, p = 0.02); in reaction time, between G1 and G2 (% = 200.0%, p = 0.01) and between pre and post G2 (% = 114.3%, p = 0.03). Differences are also found in the intragroup analyzes of G2 in the P3 regions (% = 33.3%, p = 0.04) and F7 (% = 73.3%, p < 0.0001). These groups resulted in greater amplitude of brain waves at some points, with an adaptation to greater electrical activity to maintain basal functional competence, indicating synaptic plasticity of the stimulated area. Intervention with physical exercise and cognitive stimulation appeared to promote a broader effect on the amplitude of alpha and beta brain waves observed in elderly people with and without MCI.
