A 46-year-old woman with a BMI of 35 reports episodes of feeling "out of control" with eating. She says that during these episodes, she eats an extremely large quantity of food in a short period of time. She eats quickly and past the point of being full, which leaves her feeling physically uncomfortable. After these episodes, she feels ashamed. She has been hiding this behavior from her friends and family for about 4 months. What is the most appropriate diagnosis?
Bulimia nervosa
Atypical eating disorder
Binge eating disorder
Avoidant-restrictive food pattern
The Correct Answer is C
Choice A reason: Bulimia nervosa involves binge eating followed by compensatory behaviors (e.g., vomiting, laxatives, excessive exercise). This patient does not engage in compensatory behaviors, ruling out bulimia.
Choice B reason: Atypical eating disorder is a vague term not defined in DSM-5. This diagnosis is not specific enough to describe her behavior.
Choice C reason: This is the correct answer. Binge eating disorder is characterized by recurrent binge episodes with a sense of loss of control, eating rapidly, and feelings of shame, without compensatory behaviors. Her BMI and 4-month history fit these criteria.
Choice D reason: Avoidant-restrictive food intake disorder involves avoidance or restriction of food intake leading to nutritional deficiency or weight loss. The patient’s issue is overeating, not restriction.

Correct Answer is A
Explanation
Choice A reason: Neuroimaging studies in children with ADHD often show reduced total brain volume, particularly in the prefrontal cortex, basal ganglia, and cerebellum, supporting neurodevelopmental involvement in the disorder.
Choice B reason: Slow-wave activity on EEG may be altered in some neurodevelopmental disorders, but decreased slow-wave activity is not a specific marker for ADHD.
Choice C reason: Thalamic volume reduction is not consistently associated with ADHD; abnormalities are more commonly observed in cortical and subcortical structures.
Choice D reason: ADHD is associated with delayed cortical maturation, particularly in the prefrontal cortex, rather than early posterior-to-anterior cortical maturation.
Correct Answer is C
Explanation
Choice A reason: The Child Behavior Checklist is a broad behavioral assessment, not specific for autism, and is more suitable for older children.
Choice B reason: The Conners Teacher Rating Scale is designed to assess ADHD symptoms in school-aged children, not toddlers.
Choice C reason: This is the correct answer. The M-CHAT is a validated screening tool for autism in toddlers aged 16–30 months and is widely used for early detection of autism spectrum disorder.
Choice D reason: The Vanderbilt Teacher Rating Scale is designed for ADHD evaluation in school-aged children and is not appropriate for autism screening in toddlers.
