Hypersomnia and narcolepsy in 42 adult patients with craniopharyngioma
Bibliographic record
Abstract
STUDY OBJECTIVES: To evaluate sleep, sleepiness, and excessive need for sleep in patients with craniopharyngioma (a suprasellar tumor which can affect sleep-wake systems). METHODS: A retrospective study of all adult patients living with craniopharyngioma referred to the sleep clinic, who received a sleep interview, nocturnal polysomnography, multiple sleep latency tests (MSLT), and 18-h bed rest polysomnography. Their sleep measurements were compared with those of age- and sex-matched healthy controls. RESULTS: Of 54 patients screened with craniopharyngioma, 42 were analyzed, 80% of whom complained of excessive daytime sleepiness. Sleep testing revealed that 6 (14.3%) of them had secondary narcolepsy (including one with cataplexy), and 11 (26.2%) had central hypersomnia associated with a medical disorder. Compared with controls, patients were more frequently obese, had a shorter mean sleep latency on MSLT, and slept longer on the first night. There was a nonsignificant trend for patients with (vs. without) narcolepsy and hypersomnia to be younger, to have a higher body mass index, to be more likely to have received radiation therapy, and to have more severe damage to the hypothalamus after surgery. Treatment with stimulants (modafinil, pitolisant, and methylphenidate) was beneficial in 9/10 patients. CONCLUSIONS: Nearly half of the patients with craniopharyngioma and sleep disorders have a central disorder of hypersomnolence (narcolepsy and hypersomnia), which should be investigated and lead to considerations beyond sleep apnea syndrome in these obese patients.

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.
