(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 C
Explanation
Altered levels of leptin and ghrelin.
Choice A rationale:
Increased levels of cortisol and thyroid hormones are not commonly associated with eating disorders. Cortisol is a stress hormone, and while stress can play a role in eating behaviors, it is not a consistent physiological change across all eating disorders. Thyroid hormones play a role in metabolism, but their direct link to eating disorders is limited.
Choice B rationale:
Decreased levels of growth hormone and insulin are not commonly associated with eating disorders. Growth hormone and insulin are primarily involved in growth regulation and glucose metabolism, respectively, and their alterations are not central to the core characteristics of eating disorders.
Choice C rationale:
Altered levels of leptin and ghrelin are commonly associated with eating disorders. Leptin is a hormone that regulates appetite and signals satiety. Individuals with eating disorders may have disrupted leptin levels, contributing to disturbances in appetite and hunger regulation. Ghrelin is a hormone that stimulates appetite, and its dysregulation can also play a role in eating disorder behaviors.
Choice D rationale:
Elevated levels of sex hormones and growth hormone are not consistently associated with eating disorders. While some hormonal changes can occur due to malnutrition and extreme weight loss, they are not universally seen across all individuals with eating disorders. The hormonal changes seen in eating disorders are more often related to appetite regulation and metabolism.
Correct Answer is C
Explanation
Choice A rationale:
Monitoring vital signs and weight. While monitoring vital signs and weight is an essential aspect of patient care, it primarily focuses on the physical health of the patient. In the case of an eating disorder, the underlying psychological and emotional issues also need attention, which is not addressed solely by monitoring vital signs and weight. The patient's emotional well-being and coping strategies are equally important in promoting overall recovery.
Choice B rationale:
Providing positive reinforcement for eating. Positive reinforcement can be helpful in encouraging desired behaviors; however, focusing solely on positive reinforcement for eating might oversimplify the complexities of treating an eating disorder. Eating disorders are often rooted in psychological factors, and addressing the underlying causes and emotions is crucial. Providing positive reinforcement might not address the emotional challenges the patient is facing, and a more comprehensive approach is needed.
Choice C rationale:
Teaching coping skills and stress management techniques. This is the correct choice. Eating disorders are often connected to emotional distress, poor body image, and stress. Teaching coping skills and stress management techniques empowers the patient to develop healthier ways of dealing with emotions and triggers that may contribute to their eating disorder. By addressing the emotional aspect, the patient is better equipped to manage their disorder and work towards recovery.
Choice D rationale:
Involving the family in the treatment process. Involving the family in the treatment process can be beneficial, as family support is important for recovery. However, it's not the most appropriate intervention on its own. Eating disorders are complex and individualized, and addressing the patient's personal coping mechanisms and emotional well-being should be the primary focus. Family involvement can be part of a comprehensive treatment plan, but it should not replace teaching the patient coping skills and stress management techniques.
