Background: Social cognition is widely studied in neurology. At present, such evaluations are designed for research or for specific diseases and simple general clinical tools are lacking. We propose a clinical evaluation tool for social cognition, the Geneva Social Cognition Scale (GeSoCS). Methods: The GeSoCS is a 100-point scale composed of 6 subtests (theory of mind stories, recognition of social emotions, false beliefs, inferences, absurdity judgement and planning abilities) chosen from different validated tests of social and cognitive evaluation. Eighty-four patients with neurological disorders and 52 controls participated in the study. Evaluation duration lasted 20-60 min. Results: Mean scores were 92.6 ± 4.5 for controls and 76.5 ± 15.3 for patients and differentiate patients and controls in all subtests. With a cut-off score of 84, the scale had a sensitivity of 62% and a specificity of 94%. In our stroke subgroup, right CVAs failed in cartoons, inferences, ‘mind in the eyes', and in the temporal rule task while left CVAs were impaired in verbal/discourse tasks (social cognition, inferences, absurd stories, and cartoons. Conclusions: The GeSoCS is a medium duration assessment tool that appears to detect and characterize significant social impairment in neurological patients.
