Theory of mind, empathy and eye gaze strategies during observation of a work of art: neurodegenerative pathologies.

Objective: Theory of mind (ToM) and empathy are severely impaired in the behavioural variant of frontotemporal dementia (bvFTD) and more mildly in Alzheimer's (AD) and Parkinson's diseases (PD). Such impairments are associated with behavioural disorders. Modification of visual scanning strategies of complex visual scenes is also found in these pathologies.
