Studies have identified the existence of a connection between DiabetesMellitus and dementia. High blood sugar level can be a significant factor of the incidence of Alzheimer, which could be a secondary cause of dementia. Other research revealed that the executive functions of the elderly with DM were more impaired than in those without DM. Type 2 Diabetes Mellitus (DM2) is associated with cognitive and functional deficits and, one of the tools, which can be used to assess executive functions, is the Wisconsin Card Sorting Test (WCST). A systematic review was performed with the aim ofverifying the characteristics of indexed publications in the last eight years,using the following subjects: Type 2 Diabetes, elderly people, the WCST,thought and cognitive flexibility, and executive functions. Results show that studies involving DM2, elderly people and WCST are few.
