Abstract

fetched live from OpenAlex

Background: Seizures in childhood absence epilepsy (CAE) are usually easily controlled with anti-seizure medications (ASMs). Factors predictive of treatment resistance remain unclear. Our objectives were to assess prevalence of neuropsychiatric problems and factors influencing refractoriness in a cohort of CAE at a single centre. Methods: We retrospectively reviewed patients with CAE (ILAE 2017 classification) diagnosed between January 1999 and December 2016 with at least 1-year follow-up. Treatment resistance was defined as failure to respond to two or more appropriate ASMs. Exclusion criteria included eyelid myoclonia with absence, myoclonic absence, and generalized tonic-clonic (GTC) seizure before developing absences. Results: The study population comprised 164 patients (65 males) 6.25-year-old on average at absence onset. 22% had treatment-resistant seizures. The first ASM was Ethosuximide in 63.4%, Valproic acid in 23.2%, and Lamotrigine in 6.7%. Statistical differences between response groups included developing a second seizure type specifically GTC, the second and third ASM, and absence of EEG normalization. At last follow-up, 43.3% of children were seizure-free off ASMs. 32.9% of children had learning disabilities, 28% ADHD, and 12.8 % anxiety. Conclusions: 22% of children with CAE had treatment-resistant seizures. Photoparoxysmal response was not predictive of treatment resistance. Neuropsychiatric problems were common with learning disabilities increased with refractory absences.

Not 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.
