Association between facial emotion recognition and odor identification in schizophrenia.

The authors examine facial emotion recognition and unirhinal olfactory performance in 19 schizophrenia patients and 14 comparison subjects. In patients, right nostril odor identification performance was positively related to overall emotion recognition accuracy, specifically, sad facial expressions. Olfactory and emotion recognition abilities appear significantly linked in schizophrenia.
