Idiopathic REM sleep behavior disorder
Bibliographic record
Abstract
REM sleep behavior disorder (RBD) is a parasomnia characterized by a lack of motor inhibition during REM sleep leading to potentially harmful dream-enacting behaviors. RBD affects mainly older men and its prevalence in the general population is estimated to be around 0.5%. RBD may be idiopathic or associated with other neurologic disorders. A strong association between RBD and alpha-synucleinopathies has been recently observed, with the parasomnia often heralding the clinical onset of the neurodegenerative disease. The idiopathic form accounts for up to 60% of the cases reported in the three largest series of patients with RBD. Small clinical follow-up studies revealed that a proportion of these patients will eventually develop a parkinsonian syndrome or a dementia of Lewy bodies type in the years following the RBD diagnosis, while some patients will never show other neurologic signs within several decades from the RBD onset. Recent studies have looked at neurophysiologic and neuropsychological functions in idiopathic RBD and have found evidences of CNS dysfunction during both wakefulness and sleep. An impairment of the cortical activity, specific neuropsychological deficits, and signs of autonomic dysfunction have been observed in a variable proportion of these patients, challenging the concept of idiopathic RBD. Identifying subjects with a high risk of developing a neurodegenerative process may be crucial in order to develop early intervention strategies.

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.
