Transient Hemichorea/Hemiballismus Associated with New Onset Hyperglycemia
Bibliographic record
Abstract
OBJECTIVE: To describe three patients suffering from transient hemichorea/hemiballismus associated with hyperglycemia, review previous reports and propose a possible pathophysiological explanation for this phenomenon. RESULTS: Our original cases and previously reported ones reveal a uniform syndrome: mostly female patients (F/M ratio of 11/2), 50-80 years old, usually with no previous history of diabetes mellitus (9/13), develop choreic or ballistic movements on one side of the body over a period of hours. Serum glucose levels are elevated. In most of the patients, a lowering of the blood sugar level reverses the movement disorder within 24-48 hours. CONCLUSIONS: We believe that the combination of a recent or old striatal lesion (causing increased inhibition of the subthalamic nucleus) and hyperglycemia (causing decreased GABAergic inhibition of the thalamus) may be responsible for the appearance of this unilateral hyperkinetic movement disorder. Undiagnosed diabetes mellitus should always be suspected in patients who develop hemiballistic or hemichoreic movements. When hyperglycemia is detected and corrected, the movement disorder usually resolves within two days and may not require symptomatic therapy with dopamine receptor antagonists.

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.
