What is one key role of electroencephalography in the pediatric epilepsy workup?

• A. Measure Blood Pressure
• B. Localize And Classify Seizures
• C. Predict Personality
• D. Diagnose Metabolic Disorders

Answer: (B)

Electroencephalography records the brain’s electrical activity over time, and in the pediatric epilepsy workup its primary role is to localize where seizures begin and to classify the seizure type based on EEG patterns. This helps determine whether seizures are focal or generalized and guides treatment decisions, including the potential for surgical planning in focal epilepsy and the choice of antiseizure medications. For example, focal epileptiform discharges point to a localized onset, while generalized spike-and-wave patterns suggest a different, widespread type. Other options don’t fit EEG’s purpose: blood pressure is a separate vital sign, personality is not assessed by EEG, and diagnosing metabolic disorders relies on lab tests and metabolic studies rather than EEG findings.
