Socioemotional dysfunction relates to financial exploitation vulnerability in Alzheimer’s disease and behavioral variant frontotemporal dementia

Our results suggest that FEV is a more severe problem in bvFTD than AD but distinctly related to socioemotional dysfunction in both groups, including impaired self-awareness and unwillingness to accept unfair offers in simulated social decision-making tasks. LTPJ atrophy, critical to perspective-taking, may also increase FEV susceptibility. Both socioemotional dysfunction itself, and a patient's lack of awareness for their own deficits (i.e., anosognosia) may potentially be an important early risk factor for FEV.
