Which neurobehavioral disorder is listed among those assessed in the exam?

• A. Parkinson disease
• B. Diabetes mellitus
• C. Asthma
• D. Hyperthyroidism

Answer: (A)

Neurobehavioral disorders are conditions where brain disease or dysfunction presents with significant behavioral, mood, or cognitive symptoms that impact mental status. Parkinson disease fits this since, beyond its characteristic movement problems, it frequently includes non-motor neuropsychiatric features—depression, anxiety, apathy, sleep disturbances, and cognitive changes—that affect how a patient performs on a mental status exam. The other options are systemic medical conditions (diabetes mellitus, asthma, hyperthyroidism) whose primary issues are metabolic, respiratory, or endocrine and are not categorized as neurobehavioral disorders in the typical mental status assessment context. Thus, Parkinson disease is the appropriate choice.
