Which disorder is described as neither clearly developmental nor acquired?

• A. Epilepsy
• B. Autism
• C. Cerebral palsy
• D. ADHD

Answer: (A)

Epilepsy isn’t tied to a single origin like clearly developmental disorders (which arise from disrupted brain development in early life) or clearly acquired brain injuries (which come from trauma or disease after birth). Instead, it spans a range of causes: genetic or congenital factors can set up a predisposition for seizures, while other cases result from structural brain changes or injuries acquired later (such as after a stroke, infection, or trauma). Some people have seizures with no identifiable cause. Because its hallmark is recurrent unprovoked seizures and its etiologies are so varied—ranging from developmental to acquired—epilepsy doesn’t fit neatly into either category.
