Abstract

CUSTODIO, Nilton et al. Utility of the INECO´s executive and social cognition battery in the evaluation of executive functions in Peruvians patients with behavioral variant frontotemporal dementia. Rev Neuropsiquiatr [online]. 2015, vol.78, n.4, pp.211-220. ISSN 0034-8597.

Behavioral variant fronto temporal dementia (bvFTD) is characterized by early and substantial ventromedial prefrontal cortex (VMPFC) dysfunction and there is no consensus regarding which tests are most sensitive and specific to assess it. Objectives: To detect specific xecutive and social cognitive deficits in patients with early behavioural variant fronto temporal dementia. Materialand Methods: In this study we assessed with the INECO´s Executive and Social Cognition Battery, which included Theory ofMind tests(Mind in the Eyes, Faux Pas), the Hotel Task, Multiple ErrandsTask-hospital version and the Iowa Gambling Task for complex decision-making.Patients were divided into two groups according to their Addenbrooke’s Cognitive Examination scores. Results: We found that low Addenbrooke’s Cognitive Examination patients differed from controls on most tasks of the standard battery and the Executive and Social Cognition Battery. But high Addenbrooke’s Cognitive Examination patients did not differ from controls on most traditional neuropsychological tests, while significant differences were found between this high-functioning behavioural variant of frontotemporal dementia group and controls on most measures of Executive and Social Cognition Battery. Conclusions: The INECO´s Executive and Social Cognition Battery used are more sensitive in detecting executive and social cognitive impairment deficits in early behavioural variant of frontotemporal dementia than the classical cognitive measures.
