0788 Sleep Characteristics Of Children With Tourette Syndrome And Explosive Outbursts
Bibliographic record
Abstract
Tourette Syndrome (TS) is defined by motor and sound tics. Opposition and aggressive behaviors are common in children with TS, and some even experience explosive outbursts. These sudden and recurrent events are considered the worst symptoms by parents because of their severe interference with daily functioning. It is estimated that about 25% of children with TS will have sleep problems. Since inadequate sleep exacerbates behavioral symptoms of children with psychiatric disorders, we investigated whether poor sleep and explosive outbursts are association together in children with TS. Seven boys with TS (9.4±1.1 years old) and enrolled in a cognitive-behavioral program aiming at decreasing explosive outbursts were recruited. Sleep was recorded with actigraphy for 2 consecutive weeks prior to the intervention and parents filled a sleep diary during the same period as well as after the intervention. Both the mothers and the fathers filled the Children Sleep Habits Questionnaire (CSHQ) before and after the intervention. Explosive outbursts were scored from 1 (less severe) to 10 (more severe). The average actigraphy data over 2 weeks for the 7 children was not atypical, including sleep latency (26.9 ± 4.0 min.), total sleep time (493.1 ± 19.5 min.) and sleep efficiency (90.8% ± 1.1%). Three out of the 7 participants experienced explosive outbursts during the actigraphy recording period, for a total of 8 events (mean severity score: 6.3 ± 0.9). There were no differences in actigraphy variables extracted from the nights preceding and those immediately following the explosive outbursts. During the pre-intervention period, mothers and fathers responded in similar ways to the CSHQ (total score 49.4 ± 2.9 vs 46.4 ± 1.7, respectively), but mothers reported more parasomnias (11.1±1.2 vs 9.6±1.3; p<0.01). All of the children exceeded the CSHQ clinical cut-off of 41. Post-intervention analyses are currently being analyzed. Children with TS display signs of sleep disorders according to CSHQ scores but not actigraphy. Explosive outbursts do not seem to be preceded nor followed by particular sleep patterns.

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.
