The Movement Disorder of Brain-Lung-Thyroid Syndrome Can be Responsive to Methylphenidate
Bibliographic record
Abstract
Benign hereditary chorea is a rare disorder characterized by childhoodonset, non-progressive chorea, with or without associated respiratory and thyroid dysfunction.1 It is referred to as ‘‘brain-lung-thyroid’’ syndrome when all three systems are involved.2 It is caused by autosomal dominant mutations in the NKX2-1 gene (previously TITF-1), on chromosome 14.3 It is a genetically heterogeneous condition, with over 30 different causative mutations identified.4 Other neurological manifestations of benign hereditary chorea and NKX2-1-related disorders include dystonia, myoclonus, tics, tremor, dysarthria, ataxia, hypotonia, and motor developmental delay. Neuropsychiatric symptoms such as attention deficit hyperactivity disorder (ADHD), have also been reported.1,5 Pharmacologic treatment of chorea and other abnormal movements in NKX2-1-related disorders has been disappointing. It typically involves levodopa or tetrabenazine; however, side effects are often limiting.5 We report and illustrate the case of a young female patient with brain-lung-thyroid syndrome and an immediate improvement of her involuntary movements with methylphenidate (Video 1).

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.
