Yes. And for bilingual patients, there seems to be a greater effect on the more recently acquired language:
> Southwood et al[49] make the same recommendation based on oral interviews conducted with a single male patient who displayed more language disturbances in his second language than in his native language. Armon-Lotem et al[50] also describe schizophrenia patients who display more problems in their second language than in their first. Smirnova et al[42], in their study of 10 Russian Hebrew bilinguals with a diagnosis of schizophrenia, also found that some syntax and semantic impairments were more pronounced in the later-learned language.
