The aim of this paper was to review the limited, but growing, literature on prospective memory (PM) following stroke using a scoping study methodology. Multiple databases were systematically searched and yielded 11 studies that were classified as observational (n = 7) or intervention studies (n = 4) and reviewed for quality. PM impairment after stroke was more commonly identified using behavioural measures compared to self-report measures. There were mixed findings regarding the extent and nature of PM impairment poststroke; however, more studies reported impairment for time-based PM, compared to both event- and activity-based PM. Studies examining rehabilitative techniques for PM resulted in mixed findings and were limited as most were case studies of poor methodological quality. Overall previous research in this area was limited as most studies were often underpowered due to small sample sizes, or used single-item measures which may not be robust enough to reliably measure PM impairment. Additionally, the methods used to measure PM were varied and many studies did not control for retrospective memory impairment, which could impact the results, as PM has both a retrospective (remembering both the action and when it needs to be completed) and prospective component (remembering to perform the action when appropriate). In conclusion, PM impairment is apparent poststroke, specifically for time-based PM. However, more research is needed to determine why PM impairment occurs, and how it can be improved.
