Prospective memory has been increasingly investigated in cognitive aging research and has shown particular sensitivity to the early stages of dementia. Prospective memory is theorized to involve executive functions. Previous research has shown that executive function is predictive of performance on complex prospective memory tasks; however, task type and difficulty appear to account for mixed findings in the literature. This research describes an event-based prospective memory protocol that was designed for assessing diverse older adults in a Rural and Remote Memory Clinic. The task requires individuals to remind the examiner to perform a task when an external cue is provided. A series of three prompts is provided if the cue is not acted upon successfully. The task was administered to a sample of healthy (n=32) and clinical (n=102) participants. In healthy adults, the mean number of cues required was one and 39% of participants retrieved the correct action at the first external cue. This test was sensitive to mild cognitive impairment (59% of individuals required all prompts) and Alzheimer disease (76% required all prompts). Conversely, only 33% of individuals with FTD required the maximum prompts. Results suggest that protocol involved fewer executive functions relative to retention and retrieval demands.
