(Question from external source) Which of the following is a common neurobiological change associated with eating disorders?
Altered activity of serotonin, dopamine, and norepinephrine.
Altered structure and function of brain regions involved in processing hunger and satiety.
Altered connectivity and communication between brain regions and networks.
All of the above.
The Correct Answer is D
Choice A rationale:
Altered activity of serotonin, dopamine, and norepinephrine is a common neurobiological change associated with eating disorders. These neurotransmitters play key roles in mood regulation, reward pathways, and appetite control. Altered levels of these neurotransmitters can contribute to the development and maintenance of disordered eating behaviors.
Choice B rationale:
Altered structure and function of brain regions involved in processing hunger and satiety are commonly observed in individuals with eating disorders. Brain areas such as the hypothalamus, amygdala, and prefrontal cortex, which are responsible for regulating appetite, emotions, and decision-making, can exhibit changes in their neural activity and connectivity due to the impact of prolonged malnutrition and distorted eating behaviors.
Choice C rationale:
Altered connectivity and communication between brain regions and networks is another neurobiological change seen in eating disorders. The brain operates through complex networks, and disruptions in the communication between different regions can lead to dysfunctional behaviors and cognitive processes related to eating and body image.
Choice D rationale:
This choice is correct. All of the aforementioned changes—altered neurotransmitter activity, changes in brain structure and function, and altered connectivity between brain regions—are commonly observed in individuals with eating disorders. These neurobiological alterations underscore the complex interplay between biological, psychological, and environmental factors in the development and progression of these disorders.

Correct Answer is A
Explanation
Eating until feeling uncomfortably full.
Choice A rationale:
Eating until feeling uncomfortably full is a characteristic of binge eating disorder. Binge eating involves consuming an excessive amount of food within a discrete period while feeling a lack of control over eating. This often results in physical discomfort due to the large quantity of food consumed.
Choice B rationale:
Recurrent episodes of binge eating followed by inappropriate compensatory behaviors are more characteristic of bulimia nervosa, not binge eating disorder. In binge eating disorder, there is no consistent use of inappropriate compensatory behaviors such as vomiting or excessive exercise to counteract the binge episodes.
Choice C rationale:
Eating more rapidly than normal can be a characteristic of binge eating episodes, but it is not a defining feature of binge eating disorder. Binge eating disorder is primarily characterized by the consumption of large amounts of food within a short period and the sense of lack of control during these episodes.
Choice D rationale:
Recurrent episodes of night eating is not a characteristic of binge eating disorder. Night eating disorder is a separate condition characterized by consuming a significant portion of daily caloric intake during the nighttime hours.
Questions
.
Correct Answer is A
Explanation
Choice A rationale:
Significant weight loss or failure to achieve expected weight gain is consistent with the diagnosis of avoidant/restrictive food intake disorder (ARFID) ARFID is characterized by a lack of interest in eating or food, avoidance based on sensory characteristics of food, concern about the aversive consequences of eating, and avoidance of foods due to a previous negative experience. This avoidance can lead to inadequate nutrient intake and, consequently, significant weight loss or the inability to achieve expected weight gain, especially in children.
Choice B rationale:
Recurrent episodes of binge eating followed by inappropriate compensatory behaviors are not indicative of avoidant/restrictive food intake disorder (ARFID) This behavior is more characteristic of bulimia nervosa, which involves cycles of binge eating followed by behaviors like vomiting, laxative use, or excessive exercise to compensate for the overeating.
Choice C rationale:
Persistent eating of nonnutritive, nonfood substances is a characteristic of pica disorder, not avoidant/restrictive food intake disorder (ARFID) Pica involves the consumption of substances such as dirt, paint, hair, or cloth, which have no nutritional value.
Choice D rationale:
Repeated regurgitation of food is a characteristic of rumination disorder, not avoidant/restrictive food intake disorder (ARFID) Rumination disorder involves the regurgitation of food that is then either re-chewed, re-swallowed, or spit out, without an associated medical condition.
