Cognitive remediation therapy in bulimia nervosa: A case studyTerapia de remediación cognitiva en bulimia nerviosa: Un estudio de caso

Abstract

The aim of this study was to perform a preliminary evaluation of cognitive remediation therapy (CRT) in a patient with bulimia nervosa (BN). The participant was 20 years old with a 22.41kg/m2 body mass index (BMI). Under a pre-post treatment design, the patient was administered four neuropsychological tests, three measures of BN symptoms and two of psychiatric symptomatology (depression and anxiety). Based on the pre and post CRT scores, the objective clinical change (OCC) was calculated. The main neuropsychological effects were observed in cognitive flexibility, visoconstructive processing (memory and central coherence) and working memory (OCC = 0,39-0,99). Relevant changes were also identified in the measures of psychiatric symptomatology and BN (OCC = 0,53-0,88), with no change in BMI. This study adds evidence regarding the usefulness of CRT in the multidisciplinary treatment not only of anorexia nervosa, but also extends its applicability to another eating disorder, BN.
