Neurobehavioral disorders assessed include which of the following?

• A. Dementia, delirium, depression, psychosis, Parkinson disease, stroke, neuropathy, and multiple sclerosis
• B. Diabetes, hypertension, hyperlipidemia
• C. Migraine, cluster headaches, tension-type headaches
• D. Epilepsy only

Answer: (A)

Neurobehavioral disorders are conditions where brain dysfunction leads to changes in thinking, mood, behavior, or cognition. The best answer packs a broad range of problems that illustrate how brain pathology can manifest as behavioral or cognitive symptoms. Dementia and delirium are classic examples of cognitive and attentional disturbances tied to brain disease. Depression and psychosis reflect mood and thought disorders arising from neurological or neurochemical changes. Parkinson disease is a neurodegenerative movement disorder that often comes with cognitive and behavioral changes. Stroke can produce focal brain injury that disrupts cognition and behavior, and multiple sclerosis can affect thinking, mood, and behavior through demyelination and brain changes. Neuropathy, while primarily a peripheral nerve issue, can contribute to functional and behavioral impacts due to chronic symptoms and disability, fitting into the broader neurobehavioral picture. The other options miss these core brain-behavior relationships or focus on conditions that aren’t primarily neurobehavioral in nature, such as systemic medical risk factors, pure headache syndromes, or epilepsy alone.
