This symptom occurs several times a day and lasts only a few seconds. During these episodes, the boy does not respond to verbal or physical stimulation, and his parents deny him falling down or shaking. After the episode, the boy returns to his normal activity and is not confused. The parents deny any history of head trauma, recent medication use, or infection. Neurological exam is unremarkable. His episode is precipitated as he blows at a pinwheel. An EEG is performed, which shows 3-Hz spike and waveform. Which of the following is the best treatment option for this patient?? A: Ethosuximide, B: Levetiracetam, C: Lamotrigine, D: Valproic acid, E: Zonisamide,  <response>: This is a clinical vignette describing a 5-year-old boy with brief episodic loss of awareness and responsiveness triggered by blowing on a pinwheel, without other neurological deficits. An EEG showed 3 Hz spike-and-wave activity, consistent with childhood absence epilepsy. The key features pointing to absence seizures are the brief loss of awarenessresponsiveness without other symptoms, precipitated by a specific trigger, normal neurological exam, and EEG showing 3 Hz spike-and-wave discharges. Ethosuximide, valproic acid, and lamotrigine are first-line treatments for absence seizures. Levetiracetam and zonisamide are not first-line options. Of the first-line options, ethosuximide is specifically indicated for and most effective at treating absence seizures.A: Ethosuximide
