  • Impaired recognition of happy facial expressions in bipolar disorder

  • Journal:
    Acta Neuropsychiatrica / Volume 26 / Issue 4 / August 2014
    Published online by Cambridge University Press:
    09 April 2014, pp. 253-259
  • Background

    The ability to accurately judge facial expressions is important in social interactions. Individuals with bipolar disorder have been found to be impaired in emotion recognition; however, the specifics of the impairment are unclear. This study investigated whether facial emotion recognition difficulties in bipolar disorder reflect general cognitive, or emotion-specific, impairments. Impairment in the recognition of particular emotions and the role of processing speed in facial emotion recognition were also investigated.

    Methods

    Clinically stable bipolar patients (n = 17) and healthy controls (n = 50) judged five facial expressions in two presentation types, time-limited and self-paced. An age recognition condition was used as an experimental control.

    Results

    Bipolar patients’ overall facial recognition ability was unimpaired. However, patients’ specific ability to judge happy expressions under time constraints was impaired.

    Conclusions

    Findings suggest a deficit in happy emotion recognition impacted by processing speed. Given the limited sample size, further investigation with a larger patient sample is warranted.
