[Attention and executive functions in patients with severe obesity. A controlled study using the Attention Network Test].

In this paper, attention and temperament are compared between 41 severely obese patients with psychiatric comorbidity and 45 control persons. Networks of attention were assessed by the Attention Network Test: alerting (ability to achieve and maintain an alert state), orienting (ability to orient to a stimulus), and executive attention (ability to resolve conflict). According to hypotheses, obese patients show reduced executive attention, more effortful control, and higher negative affectivity than controls. The concept of attention networks is related to cognitive mechanisms of self-regulation, opening new perspectives for understanding psychiatric disorders.
