Anorexia nervosa – a eating disorder that makes people obsessed with their weight – could alter brain circuits and affect its taste-reward treatment mechanisms, particularly for sugar, according to one study.
Taste things, those with eating disorders badociate taste with weight gain and try to avoid it.
The study showed that cerebral activation of the group of anorexia was inversely related to any pleasant experience of eating sugar.
Those who are already worried about form and weight become even more worried. And a strong response that says "feed me" could be overwhelming and trigger more dietary restrictions instead of eating.
This is because a brain reward circuit badociated with dopamine becomes more active but also triggers anxiety. "When you lose weight, your brain's response increases, but instead of driving, we think that it increases anxiety in anorexia nervosa, which makes them want to further restrict, which becomes then a vicious circle ". Frank of University of Colorado School of Medicine in the United States.
For the study, published in the journal JAMA Psychiatry, the team examined more than 100 participants including 56 adolescent girls and young adults with anorexia nervosa aged 11 to 21 years and 52 participants in good health.
The team also found that a higher brain response resulted in greater avoidance of injury – an anxiety for excessive anxiety and fears – in people with anorexia nervosa. In these patients, it promotes thinness and stimulates body dissatisfaction.
"An Improved Response to the Dopaminergic Reward System is an Adaptation to Starvation People at Risk of Anorexia Nervosa May Be Particularly Sensitive to Dietary Restrictions and Adaptations to the Developmental Period," notes the study .
