The neurocognitive impact of loneliness and social networks on social adaptation.

Social adaptation arises from the interaction between the individual and the social environment. However, little empirical evidence exists regarding the relationship between social contact and social adaptation. We propose that loneliness and social networks are key factors explaining social adaptation.

Integration of Intention and Outcome for Moral Judgment in Frontotemporal Dementia: Brain Structural Signatures.

Background: Moral judgment has been proposed to rely on a distributed brain network. This function is impaired in behavioral variant frontotemporal dementia (bvFTD), a condition involving damage to some regions of this network. However, no studies have investigated moral judgment in bvFTD via structural neuroimaging.

Orbitofrontal and limbic signatures of empathic concern and intentional harm in the behavioral variant frontotemporal dementia.

Perceiving and evaluating intentional harms in an interpersonal context engages both cognitive and emotional domains. This process involves inference of intentions, moral judgment, and, crucially, empathy towards others' suffering. This latter skill is notably impaired in behavioral variant frontotemporal dementia (bvFTD).
