Introduction: Decline in memory functioning, language, executive functions, and visuospatial skills are part of the normal aging process. However, a mild cognitive impairment, greater than expected for age, can be considered a clinical state intermediate between normal cognitive aging and mild dementia. Based on research and studies carried out regarding the evaluation of cognitive functioning in the elderly and with the intention of anticipating the identification of the appearance of a possible degenerative dementia especially in this public, an application was created in the year 2014. It consists of a fast-computational test and objective, developed by three students of the PUCRS Faculty of Informatics in partnership with the Brain Institute of Rio Grande do Sul (InsCer), iPad version that is titled "Teste seu Cérebro." This application aims to evaluate 10 (ten) cognitive functions of the elderly, through interactive and attractive tests, and can be applied simply and quickly by any health professional, caregivers and family members of the patient. This research aimed to validate the performance scores of the elderly in the "Teste seu Cérebro", by comparing the results of two tests used (MoCA and "Teste seu Cérebro). Objectives: Validate the "Teste seu Cérebro" iPad app by comparing the results with MoCA gold standard. With this data, establish cut-off point between scores of normal and MCI elderly, allowing the verification of probable risk for dementia disease. Methods: In a cross-sectional study, MoCA gold standard scores were used to evaluate the cognitive functioning of the elderly and to compare with the results of their “Teste seu Cérebro”. These results served as a parameter to validate the application and establish the cutoff point between normal and MCI elderly. This evaluation includes functions such as memory, attention/orientation, fluency, language and visuospatial skills. The sample consisted of a group of elderly individuals who attended the neuropsychology outpatient clinic of the São Lucas Hospital of the Pontifical Catholic University of Rio Grande do Sul and the general community, mostly residents of the city of Porto Alegre / RS. A total of 104 volunteers were evaluated for this study. Results: Our sample consisted of 104 participants with mean age of 70.3 (SD = 6.6), with a minimum age of 60 and maximum of 87 years. An acceptable reliability (αC> 0.600) was achieved for the TC application through internal consistency analysis by the McDonald Omega coefficient. We used Pearson's correlation coefficient to compare the general scores of the two instruments (TC and MoCA), where the result showed a statistically significant correlation, positive and classified as moderate (r=0.616; p<0.001). The average cut-off score of the “Teste seu Cérebro” to detect the cases classified as MCI by the MoCA test was obtained through the ROC curve which indicated a percentage of 89.5 points. No influence of sociodemographic variables such as sex, age and schooling on the linearity relationship between the TC and MoCA instruments was identified. Conclusion: The results suggest that the “Teste seu Cérebro” instrument can be safely used to early identify the presence of mild cognitive impairment in the elderly population, which may evolve into a dementia, with rapid execution and immediate results. New studies will be directed to the validation of the TC instrument in the identification of other types of cognitive disorders, in addition to MCI.
