Genetic testing in pediatric epilepsy evaluation helps primarily with which purpose?

• A. Detecting non-neurological diseases only
• B. Identifying etiologies and guiding therapy
• C. Replacing MRI
• D. Curing the epilepsy

Answer: (B)

Genetic testing in pediatric epilepsy evaluation is most useful for identifying the specific genetic cause of the seizures and using that information to guide treatment. Knowing the exact mutation can reveal which therapies are most effective or best avoided, help predict the epilepsy’s course, and point to targeted or non-drug approaches (like dietary therapies or clinical trials) that match the genetic syndrome. It also aids in identifying potential associated conditions and in providing genetic counseling for families. It does not replace MRI, which shows structural details of the brain, and a genetic test by itself does not cure epilepsy.
