Childhood absence epilepsy typically begins in which age range, and what is the usual treatment response?

• A. 1-3 Years; Poor Response to Typical Antiepileptics
• B. 11-15 Years; Requires Polypharmacy
• C. 4-10 Years; Good Response to Ethosuximide or Valproate With Infrequent Seizures
• D. At Birth; Resolves Spontaneously

Answer: (C)

Childhood absence epilepsy typically presents in school-age children, most commonly starting between ages 4 and 10. The seizures are brief lapses of consciousness (staring spells) and, with appropriate medication, tend to be well controlled. Ethosuximide is a classic first-line choice because it specifically targets the thalamocortical oscillations that underlie absence seizures. Valproate is also effective, particularly if there are additional generalized seizure types or other considerations. When treated effectively, seizures are infrequent, and many children experience a good prognosis with eventual remission during adolescence. This combination of onset in 4–10 years and a strong, good-response treatment profile aligns with the answer described.
