Abstract

We hypothesized that in acute stroke, some patients show structure-specific, task-independent
deficits in sentence comprehension, with chance level of accuracy on passive reversible
sentences, more impaired comprehension of object-cleft than subject-cleft sentences, and more
impaired comprehension of reversible than irreversible sentences in both sentence-picture
matching and enactment tasks, but that this pattern of "asyntactic comprehension" is associated
with impaired working memory rather than dysfunctional tissue in Broca's area as previously
proposed. We found that the pattern did exist, but was often independent of both impaired
working memory and ischemia in Broca’s area (which were less often independent of one
another).
