Systemic arterial hypertension is a disease with high prevalence in several countries, including Brazil. Many studies have correlated hypertension with accelerated loss of cognitive function, especially executive functions. There is some evidence that working memory (WM) is compromised in these populations. However, some computerized training has been developed to rehabilitate the WM, and among them the investigators highlight the Cogmed. Thus, the aim of this study is to evaluate the effects of Cogmed training in the performance of WM and attention of hypertensive patients, as well as the impact of training in the structure and brain function.

The Cogmed is computer software designed to train visuospatial and audio-verbal working memory, and other functions associated with working memory: attention, focus and impulsiveness. It has three versions adapted to different age groups: Cogmed for younger children, about 4-7 years, which are not yet so familiar with numbers and letters; Cogmed for children over 7 years and adolescents; and Cogmed for youth and adults over 18 years. In this study we will use the version for youth and adults over 18 years.
