Perception of facial emotions in chronic schizophrenia does not correlate with negative symptoms but correlates with cognitive and motor dysfunction.

Abstract：

BACKGROUND:Appropriate expression of emotions and correct perception of emotional expression in others are important social skills which may be impaired in schizophrenia and contribute to poor social adjustment. We examined the relationship between expression of emotions as measured by affective flattening and other negative symptoms and their perception. We compared performance on tests of perception of facial emotions with that in other cognitive areas. METHODS:36 chronic schizophrenic patients on stable doses of atypical antipsychotics were assessed using tests of identification (FID) and discrimination (FDIS) of facial emotional expressions, visual retention (BVRT) and general cognitive function (Mini Mental State Examination, MMSE). Clinical symptoms were assessed with scales for the assessment of negative symptoms (SANS) and positive symptoms (SAPS). Motor symptoms were assessed with side effects (SA) and AIMS scales and Finger Tapping Test. RESULTS:Negative symptoms showed no relation to FID or FDIS. FID showed significant correlation with Visual Retention and Finger Tapping but not MMSE. CONCLUSION:The ability to identify facial emotional expressions is not related to negative symptoms in chronic schizophrenia and shares common mechanisms with visual reproduction and ability to make rapid motor movements. This suggests common defects in perceptual, timed processes consistent with postulated dysfunction of cortico-subcortical circuits.
