BBC News has published an article about Graham Pawley, who suffers from post-stroke aphasia. He ”is an unusual case in that he can understand everything but say virtually nothing back. He has to get by with ”yes” and ”no”.”
In the article we get to know Graham and his dreams about the future. The important difference between being able to say ”yes” and ”no” on one hand, and not being able to say anything else on the other hand, becomes very clear to me when reading about Graham.
