Evaluating the effect of a non‐linguistic cognitive intervention on functional communication in global aphasia: A case series study

What is already known on the subject People with global aphasia (PwGA) have the potential to make impairment level gains after intensive or prolonged speech and language therapy (SLT). However, evidence of functional communication gains is limited. Cognition plays an important role in functional communication, particularly the ability to switch to alternative means of communication and switch modalities. What this study adds Contrary to many previous studies, the findings indicate that PwGA can benefit from SLT and make functional communication gains with a relatively low dose of intervention. The findings highlight cognitive skills that appear relevant to basic functional communication abilities in PwGA. These are: attention, visual perception, semantics and non-verbal problem solving. What are the clinical implications of this work? This work suggests that clinicians should offer cognitive, non-linguistic interventions to PwGA and consider delivering intervention using little to no verbal language.
