1. IntroductionVascular dementia (VaD) is the second most prevalent type of dementia after Alzheimer's Disease (AD) (Wolters & Ikram, 2019). Emotion recognition is an important part of social cognition (SC), which is the ability to perceive, evaluate and integrate social information. Impairments in social cognition are associated with e.g. social behavioral changes and increased dependence on caregivers (e.g. Henry et al., 2016). Emotion recognition impairments are common in different types of dementia, in particular in patients with behavioral variant frontotemporal dementia (bv-FTD), but up until now, this has not been studied in patients with VaD. MethodsParticipants N= 22 VaD patients (NINDS-AIREN criteria). N= 21 bv-FTD patients (Rascovsky criteria). N= 25 AD patients (NIA-AA criteria).N= 30 healthy control subjects (HC group)Procedure We assessed emotion recognition in all participants with the Ekman 60 Faces Test (EFT), which is part of the Facial Expression of Emotions- Stimuli and Tests (FEEST; Young et al., 2002), see figure 1. The test contains 60 black and white photographs of 6 universally recognized emotional expressions (anger, sadness, disgust, fear, surprise & happiness). Figure 1: example facial affect pictures from the EFT. AimTo investigate emotion recognition performance in VaD patients compared to healthy older adults, as well as to patients with AD and bv-FTD. ResultsConclusionEmotion recognition is impaired in patients with VaD; severity of impairment is intermediate between AD and bv-FTD. With the results of this study, we urge clinicians and researchers to systematically investigate social cognition in all patients with (suspected) dementia visiting the memory clinic, including patients with VaD, and to address social cognitive impairment in consultation and treatment.

The bv-FTD group had significantly lower EFT-Total score than the AD group (p<.01).For the different emotions, VaD patients had significantly lower scores than the HC group on EFT-Sadness (p<.001), EFT-Anger and EFT-Surprise (p<.01), and EFT-Disgust (p=.01). Bv-FTD patients had significantly lower scores than the HC group for EFT-Disgust, Sadness and Surprise (p<.001), as well as EFT-Anger, EFT-Fear (both p<.01) and Happiness (p=.04). bv-FTD patients also had significantly lower scores than AD patients on EFT-Disgust and EFT-Surprise (p<.05). Finally, AD patients had significantly lower scores than the HC group on EFT-Fear and EFT-Sadness (both p=.02).
