Facial mimicry and facial feedback in Parkinson’s disease


  • Emotional change detection in patients with Parkinson’s disease (PD) is affected by a disruption of the facial feedback loop and not facial mimicry manipulation.

Why this matters?

  • Facial bradykinesia is a prominent symptom of PD, resulting in a perceived lack of emotional processing such as facial emotion recognition and mimicry.

  • A deeper understanding of facial bradykinesia, the facial feedback loop and how it is disrupted by PD will improve patients’ quality of life and well-being.
