Analyse de l'exploration visuelle par électro-oculographie motrice en tâche de cognition sociale chez des patients atteints de pathologies neurodégénératives

This preliminary study aimed to compare eye movements in social cognition tasks among normal elderly people (n = 10), elderly subjects with fronto-temporal dementia (n = 3), others with dementia of the Alzheimer's type (n = 3) and others again with Parkinson's disease (n = 3). The theory of mind (understanding of facial emotions) was explored using the “Reading mind in the eyes” test and recognition of facial emotions using pictures from the Ekman faces library. Eye movements were recorded with a Mobile EyeBrain Tracker®. The results show a link between social cognition impairments and deviant eye behaviors when decoding facial emotions, with a specific profile for each pathology. These findings encourage us to continue the study, and open new perspectives for care.
