Electroclinical features of absence seizures in childhood absence epilepsy
Bibliographic record
Abstract
OBJECTIVE: To accurately define the electroclinical features of absence seizures in children with newly diagnosed, untreated childhood absence epilepsy (CAE). METHODS: The authors searched an EEG database for absence seizures in normal children with new onset untreated absence epilepsy. Seventy consecutive children were classified into IGE syndromes. The clinical and EEG features of the seizures in the children with CAE were analyzed using video-EEG recordings. RESULTS: The authors analyzed 339 absence seizures in 47 children with CAE. The average seizure duration was 9.4 seconds and clinical features consisted of arrest of activity, loss of awareness, staring, and 3-Hz eyelid movements, but there was individual variation. Ictal EEG predominantly showed regular 3-Hz generalized spike and wave (GSW) with one or two spikes per wave; however, disorganization of discharges was common and three or more spikes per wave occurred rarely. Postictal slowing was frequent. Interictal abnormalities included fragments of GSW, posterior bilateral delta activity, and focal discharges. Although all 47 children met the current criteria for CAE, only 5 fulfilled the recently proposed criteria for CAE. CONCLUSION: The heterogeneous nature of each clinical and EEG feature of untreated absence seizures is of critical importance when determining criteria for childhood absence epilepsy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
