Treatment of Seizures and Epilepsy

QUESTIONS

1.A 20-year-old female with no risk factors for epilepsy presents with a 6-year history of refractory epilepsy, suspected to be of left temporal onset based on noninvasive evaluation. She undergoes invasive monitoring with a combined left hippocampal depth electrode inserted via a parasagittal approach along with left convexity subdural grid and strips. The following figure shows EEG recording at seizure onset (filter: 1.6–70 Hz). The marker “CO” corresponds to clinical onset. Subdural contacts are as follows: LT41–LT48 are on the superior temporal gyrus (LT41 anterior, LT48 posterior); ST1–ST8 are on the middle temporal gyrus (ST1 anterior, ST8 posterior); ST9–ST16 are on the inferior temporal gyrus (ST9 anterior, ST16 posterior); LD is placed in the hippocampus (LD1 is in the amygdala, LD6 is in the posterior hippocampus). Which of the following statements best describes the seizure onset?
