“…The most replicated ones are related to attention (Kingston et al, 1996;Lauer et al, 1999;Seed et al, 2002), working memory (Green et al, 1998;Kemps et al, 2006), cognitive flexibility (Steinglass et al, 2006;Tchanturia et al, 2004), SIP (Fowler et al, 2006;Gillberg et al, 2007;Kingston et al, 1996;Lauer et al, 1999;Seed et al, 2002;Tchanturia et al, 2004), and problem solving (Cavedini et al, 2004;Salvador et al, 2010;Tchanturia et al, 2007). It is yet to be clarified whether these impairments are caused by weight loss and BMI reduction or, conversely, if they may form the basis of the illness and be considered a determinant factor for AN to develop.…”

“…Thus, after Halmi et al (2003) suggested a common pathway might be involved both in AN and obsessive compulsive disorder (OCD), investigations attempted to focus on the frontal impairment profiles by studying cognitive capabilities located in the frontal and prefrontal cerebral areas. Several investigations demonstrated impairments in attentional capabilities (Kingston et al, 1996;Lauer et al, 1999;Seed et al, 2002), mental flexibility (Steinglass, Walsh, & Stern, 2006;Tchanturia et al, 2004), speed of information processing (SIP; Fowler et al, 2006;Gillberg et al, 2007;Kingston et al, 1996;Lauer et al, 1999), working memory (Kemps, Tiggemann, Wade, BenTovim, & Breyer, 2006), and decision making (Cavedini et al, 2004;Tchanturia et al, 2007), while others failed to replicate these findings (Cavedini et al, 2004;Gillberg et al, 2007;Kemps et al, 2006;Kingston et al, 1996;Steinglass et al, 2006;Tchanturia et al, 2007). Nonetheless, an agreement appears to exist about the severity of impairments, given that all of the authors have reported that these impairments are subtle when compared with healthy control subjects.…”

This work was aimed at obtaining a profile of neuropsychological impairments in young Spanish participants with anorexia nervosa (AN) to demonstrate that right-hemisphere and frontal capacity impairments are present not only in the acute phase but also after weight recovery in a Spanish sample compared with a healthy control group. Twelve patients with AN in the acute phase (body mass index [BMI] < 17) were compared both to 16 healthy control subjects and 12 weight-recovered AN participants (BMI ! 17) matched by age, IQ, and educational level by utilizing a wide neuropsychological battery. Differences were found between AN groups only for long-term verbal memory, which worsens as BMI increases. Among participants with AN as a group, results showed differences in speed of information processing, working memory, visual memory, and inhibition, unrelated to attentional capabilities. We cannot support the hypothesis of a specific right cerebral dysfunction in patients with AN. A general cognitive dysfunction, primarily in information processing, working memory, visual and verbal memory, as well as frontal impairments such as impulsivity and poor behavioral control, appeared unrelated to BMI. We support previous works affirming that neuropsychological impairments in AN are not a consequence of the illness but a risk factor for it to develop.

“…Another study that used the IGT to measure decision making in participants with eating disorders, though (anorexia in this case) concluded that this particular group demonstrated a deficient performance on the task in comparison with a control group and with a group of participants who had already had anorexia at another time in their lives. It has been noted that participants who have already had anorexia nervosa at some time in their past do not show results like this in the test (40). This result suggests that after an eating disorder is overcome, deficits in EF are no longer significant.…”

Nutritional and Neuropsychological Profile of the Executive Functions on Binge Eating Disorder in Obese Adults

ResumenObjetivo: examinar las relaciones entre los pacientes obesos con y sin trastorno por atracón (TA) y los perfiles neuropsicológicos de sus funciones ejecutivas. Métodos: los datos de 36 individuos obesos (IMC ≥ 30 kg/m 2 ) se dividieron en dos grupos, donde se encontró que un grupo era positivo para los signos de BED de acuerdo con la escala de Binge Eating Scale. Se realizaron dos pruebas neuropsicológicas de la función ejecutiva: la Tarea Ir/No-ir y la Tarea de Juego de Iowa (IGT). El estado nutricional fue evaluado por medidas de peso corporal, estatura y circunferencia abdominal, y de estos se calcularon los índices de masa corporal (IMC). Resultados: ambos grupos presentaron características nutricionales similares; No hubo diferencias en cuanto al estado de salud de las personas con o sin BED. Los participantes encontraron positivos para los signos de BED que tuvieron los puntajes IGT más bajos (p = 0,004), y puntuaciones de omisión IR/No-ir (p = 0,015) y comisiones (p = 0,04). Otras diferencias estadísticamente significativas también se observaron aquí entre los dos grupos. Las diferencias estadísticas en los resultados IGT se correlacionaron con BED, y se asociaron categóricamente (p = 0,005). Conclusión: los individuos obesos frecuentemente presentan deficiencias en la atención selectiva, el control inhibitorio, la toma de decisiones y la planificación que pueden estar directamente relacionados con el atracón y que está relacionado con la BED. El estado nutricional no difirió entre los dos grupos estudiados, y no mostró ninguna relación con el trastorno. AbstractObjective: To examine the relationships between obese patients with and without binge eating disorder (BED) and the neuropsychological profiles of their executive functions. Methods: Data from 36 obese individuals (BMI ≥ 30 kg/m 2 ) were divided into two groups, where one group was found to be positive for signs of BED according to the Binge Eating Scale. Two neuropsychological tests of executive function were carried out: the Go/No-go Task and the Iowa Gambling Task (IGT). Nutritional status was evaluated by measures of body weight, height and abdominal circumference, and from these, body mass indexes (BMI) were calculated. Results: Both groups presented similar nutritional characteristics; there were no differences when it came to the health status of individuals with or without BED. Participants found positive for signs of BED had the lowest IGT scores (p = 0.004), and Go/No-go omission scores (p = 0.015) and commission scores (p = 0.04). Further statistically significant differences were also observed here between the two groups. Statistical differences in the IGT results correlated with BED, and were associated categorically (p = 0.005). Conclusion: Obese individuals frequently present deficits in selective attention, inhibitory control, decision-making and planning that can be directly related to binge eating and which is linked to BED. Nutritional status did not differ between the two groups studied, and did not show any connection w...

“…Hinson et al (2006) say that it is not possible to know how many different choices were actually being deliberated in this period, only that a particular choice was ultimately made. There are some newer studies which have examined the interval after the card selection and before feedback (Tchanturia et al, 2007). We decided to examine somatic markers in that interval too, because in our opinion it better reflects increasing arousal related to the anticipation of the outcome of the concrete decision made.…”

Abstract:The aim of the research was to study somatic markers during decision-making in children aged 6-14 years. On the basis of the success in Piaget's experiments, 27 children were divided into three groups -preoperational stage, concrete operational stage and formal operational stage. Children played a modified Iowa Gambling Task while skin conductance and heart rate were measured. The somatic markers appeared during decision-making in children from the age of approximately 10 years, the period of concrete operational stage.
