Abstract Prospective memory (PM) is defined as remembering to carry out intended actions at an appropriate point in the future, and can be categorized into three types of situation: time-, event-, and activity-based tasks. PM involves brain structures such as frontal and medial temporal cortices. The aim of this study was to review the currently available literature on PM in Alzheimer's disease and Mild Cognitive Impairment patients. We performed a search on Pubmed, Medline, ScieLO, LILACS and the Co­chrane Library electronic databases from January 1990 to December 2010. The key terms used were: prospective memory, memory for intentions, delayed memory and memory for future actions, separately and also combined with the search terms dementia, Alzheimer's disease and Mild Cognitive Impairment. Both patient groups showed significant impairment in PM. Further studies are needed to verify the accuracy of PM tasks as an early marker of mild cognitive impairment, and initial dementia.
