ABSTRACTStudies on the neurocognitive deficits in behavioral variant frontotemporal dementia (bvFTD) have provided evidence that highlights the differences among two views of cognition: the social cognition in the wild (i.e., everyday behavior) and the compartmentalized social cognition of neuroscientific labo-ratories. The bvFTD is a neurodegenerative condition char-
acterized by early changes in social cognition and personality, involving specific atrophy of fronto-temporo insular networks (Piguet, Hornberger, Mioshi, & Hodges, 2011) and selective
degeneration of Von Economo Neurons (Kim et al., 2012; Nanaet al., 2018; Santillo & Englund, 2014; Santillo, Nilsson, & Englund, 2013; Seeley, 2008). The insular networks (espe-
cially their frontotemporal connections) seem to particularly affect social cognition, emotion and interoception. Recently, Adolfi et al. (2017) provided direct twofold evidence from
functional magnetic resonance imaging (fMRI) meta-analysis in healthy populations and lesion studies, suggesting that the insula and their extended networks seem to be critical for
a triangle of social cognition, emotion and interoception. Vanden Stock and Kumfor (2017) also provided an insightful sug-gestion by proposing that these results converge with deficits observed in bvFTD and their related insular atrophy. They propose a longitudinal assessment of emotion, social cognition and interoception in addition to neuroimaging measures as an impactful approach to both bvFTD characterization and neuroscientific advances of insular functioning. Here, I outline a perspective of these shared processes and their deficits in
bvFTD. I propose a theoretical approach to intercognition, or the constant blending of multiple cognitive and affective processes triggered by convergent environmental and body state sources that happens in everyday cognition (Ibanez & Garcı ́a, 2018).
En este trabajo se evidencian las diferencias entre la cognición social de la vida cotidiana y la que se estudia en los laboratorios neurocientíficos: Solo la primera implica la coordinación espontánea de múltiples procesos cognitivos simultáneos (intercognición). En base a ello se propone la existencia de déficits intercognitivos en la demencia frontotemporal que involucran la cognición social, la conciencia corporal, la emoción y la cognición.
