Dynamic facial expression processing in Parkinson’s disease


  • In a test of facial expression processing using a range of conversational and emotional dynamic facial expressions, individuals with Parkinson’s disease (PD) had similar processing compared to healthy individuals of similar age, yet both groups differed in their facial expression processing from a group of younger healthy individuals.

Why this matters

    These results suggest that deficits in facial expression processing in those with PD are due to older age and are not do indicate disease pathology, and that dynamic facial expression assessment may provide more information than the commonly used static snap shots of facial expressions.
