The increase of the elderly population with a significant load of non-communicable diseases, accelerates pathological aging and increases the risk of dementia, generating a huge health, social and economic cost for any country. Dementia does not have an effective treatment yet, therefore, the focus must remain on prevention and early diagnosis. The early stages of dementia are known as mild cognitive impairment; at this stage is still possible to mitigate the progression of the disease, however, health systems worldwide face difficulties to provide universal access to health services, due to a lack of specialists and geographical distances, interfering with the access to healthcare centers. In this scenario, WHO urged countries to implement strategies to democratize and to expand the reach of health institutions. In this document, we briefly review the global and local situation of dementias and discuss some attempts to control their progression by using revolutionary digital tools. We believe the focus should be on the population that is just beginning to show cognitive impairment.
