Aphasia and reperfusion therapies in hyper-acute settings: A scoping review

Purpose: Reperfusion therapies are medical treatments that restore blood flow either by surgical removal of a blood clot or with medications that dissolve clots. The introduction of reperfusion therapies has the potential to change the presentation of aphasia following acute ischaemic stroke (AIS). This scoping study will explore the relationship between aphasia and reperfusion therapies from a speech-language pathology perspective. Method: A systematic literature search was performed on studies published up until October 2016. Relevant studies that reported on aphasia and reperfusion therapy were assessed for quality and the relationship between the two. Results: Overall, 27 studies were identified, these studies were heterogeneous in nature. Despite speech-language pathologists filling a central role in management of aphasia, only seven of these studies mentioned involvement of speech-language pathologists, with minimal information about the precise nature of the involvement of speech-language pathology services. Conclusion: Based on this scoping review, reperfusion therapy appears to be impacting on the presentation of aphasia. A prospective study into reperfusion therapy and aphasia is required to inform speech-language pathologists on this patient population.
