Key details

• Stanford Lucile Packard Children's Hospital EMU admission on 2026-03-10 (PCU400), attending Katherine Brenda Xiong, MD.
• 24-channel International 10-20 continuous video EEG, reference-electrode recording reformatted into bipolar montages. Study abbreviated to ~5 hours because Levi pulled leads ~1930.
• Wake spike-wave index 78%, sleep spike-wave index 95-100% (from a 5-minute window 1657-1702 extrapolated across non-REM sleep).
• Sleep SWI exceeds both the traditional ESES criterion (>=85%) and the updated ESES Consortium criterion (>=50%).
• Named discharge foci - O1, O2, P4, T3, T4-T6. Multifocal and posterior/temporal predominance. No frontal/frontotemporal focus named; no Fp1 or F7 involvement reported.
• Well-formed 8-9 Hz posterior dominant rhythm, normal sleep architecture (vertex waves, symmetric spindles, POSTs). No focal slowing, no interhemispheric asymmetries.
• No seizures or push-button events.
• Pre-medication for lead tolerance only - clonidine 0.2 mg PO + risperidone 1 mg ODT ~40 min before lead placement. Levi was antiseizure-medication-naive at the time of this recording.
