Impairments in face discrimination and emotion recognition are related to aging and cognitive dysfunctions in Parkinson’s disease with dementia

Abstract: Patients with Parkinson's disease (PD) suffer from motor and non-motor symptoms; 40% would develop dementia (PD-D). Impaired face and emotion processing in PD has been reported; however, the deficits of face processing in pD-D remain unclear. We investigated three essential aspects of face processing capacity in pD-D, and the associations between cognitive, neuropsychiatric assessments and task performances. Twenty-four PD-D patients (mean age: 74.0 ± 5.55) and eighteen age-matched healthy controls (HC) (mean … Show more

“…This multicenter study comprised 116 participants (60 HHD patients and 56 healthy controls) recruited from two specialized centers (see Table 1 for demographic information). Using G*Power 3.1 36 , we performed a power estimation analysis for a one-way ANOVA, considering an alpha of α = 0.05, a power of 0.8 37 , and an effect size of η 2 = 0.17 (as a median value between η 2 = 0.08 and 0.27, based on previous reports for similar experimental tasks and samples 38 41 ). Results indicated that a total sample size of 41, considering the two groups, was enough to reach the estimated effects.…”

“…Changes in expressions mean that human faces leap from one activation state to another. This paper adopted a strategy similar to Bandini et al (4). A standard facial model, showing a calm and natural expression, was constructed as a reference model for each person.…”

“…Presenting PD patients with static faces could worsen their recognition accuracy compared to dynamic faces, artificially inflating their FER deficit [14]. Ho et al [12] has recently shown deficits in anger and disgust recognition with dynamic human faces. They reported that age, slow mentation and poor cognition were associated with FER deficit in PD patients, and not in age-matched controls.…”
