Infantile Spasms in Remission May Reemerge as Intractable Epileptic Spasms
Bibliographic record
Abstract
BACKGROUND: West syndrome consists of infantile spasms with hypsarrhythmia and is perceived as a disorder of infants. METHODS: We describe 10 patients with West syndrome with spasms that remitted, started again, and persisted (followed up for 8-25 years). RESULTS: In all, West syndrome developed at younger than 17 months (five cryptogenic, six symptomatic). With initial treatment, spasms completely stopped for 4.5 months to 6 years, when epileptic spasms returned. Recurrent spasms were typical with brief arm extension, eye elevation, and head drop without falling. Spasms lasted 2-6 s in rhythmic strings over 20- to 60-min periods and occurred daily throughout follow-up. Persistent spasms were particularly troublesome, because of incontinence in one and postictal confusion in several. During the string of spasms, most refused to interact, and several would wander off. Up to 15 antiepileptic drugs did not render any patient spasm free. Only two had persistent spasms as the only seizure type; six also had intractable complex partial seizures, and three had occasional grand mal convulsions. Interictal EEGs showed multifocal spikes. Ictal recordings in six showed electrodecremental events. CONCLUSIONS: Recurrent spasms after remission of West syndrome represent an extremely resistant, distressing form of epilepsy. The onset of West syndrome is age related, but it does not reliably vanish.

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; both teacher heads agree on what is shown here.
