(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
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.
Correct Answer is C
Explanation
Choice A rationale:
"I might need to be hospitalized to stabilize my physical condition." Hospitalization is often necessary for individuals with severe eating disorders, such as anorexia nervosa with significant medical complications. Inpatient treatment might be required to stabilize the patient's physical condition, provide proper nutrition, and address any medical complications arising from malnutrition.
Choice B rationale:
"Psychotherapy and medication can help address the psychological aspects of my disorder." Psychotherapy, often including cognitive-behavioral therapy (CBT), and medication can indeed play crucial roles in treating eating disorders. These approaches help address the underlying psychological factors contributing to the disorder and aid in promoting healthier eating behaviors. This statement indicates that the patient understands the comprehensive nature of treatment.
Choice C rationale:
"Relapse prevention strategies are not necessary once I have recovered." This statement is indicative of a misunderstanding about the nature of eating disorders. Relapse prevention strategies are essential to maintain recovery and prevent relapse. Eating disorders have a psychological component, and individuals need to continue practicing healthy behaviors, coping skills, and strategies even after they have made progress in their recovery journey.
Choice D rationale:
"Social support, such as family involvement or peer support, can be helpful in maintaining recovery." Social support is indeed valuable for individuals with eating disorders. Engaging with family, friends, or support groups can contribute to the maintenance of recovery. The statement reflects an accurate understanding of the role of social support in the treatment and recovery process.
