A new study adds to evidence that bilingualism strengthens the brain. 608 stroke patients were studied, and it was shown that post-stroke, bilinguals were more likely to enjoy normal cognition compared with monolinguals (40.5% versus 19.6%). On the other hand, there were no differences in the frequency of aphasia.
