Teaching Video NeuroImage: Clinical and EEG Hallmarks of Epilepsy With Eyelid Myoclonia
Bibliographic record
Abstract
A 14-year-old developmentally typical boy presented with daily eyelid myoclonia (EEM) with absences since age 3 years.He had a single generalized tonic-clonic seizure at age 12 years because of nonadherence to antiseizure medications.He had failed valproate, ethosuximide, and lamotrigine.Neurologic examination and brain MRI were normal.The clinical and EEG features (Figure and Video 1) were suggestive of epilepsy with EEM or Jeavons syndrome.EEM 1 is an uncommon epilepsy syndrome, more common in girls (2:1), with seizure onset between age 2 and 14 years.It is characterized by eye closure (EC)-induced EEM, infrequent GTCs, and often drug resistance.Developmental milestones are usually normal with possible mild impairments.EEG shows 3-6 Hz irregular generalized spike or polyspike waves, EC sensitivity, and photo-paroxysmal responses.EC-induced spiky posterior α-like activity and occipital spikes preceding generalized discharges may suggest occipital lobe dysfunction and entrainment of thalamo-cortical networks. 2Monogenic aetiologies (e.g., CHD2, NEXMIF, SYNGAP1) have been reported in some EEM cases with neurologic comorbidities.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
