Abstract
Mounting evidence indicates mitochondrial dysfunction in bipolar disorder pathophysiology. Here, we employed Proton Nuclear Magnetic Resonance Spectroscopy (1H NMR) of cerebrospinal fluid (CSF) samples from well-characterized bipolar disorder patients (n = 67) and healthy controls (n = 55) in order to measure absolute concentrations of multiple metabolites. Focusing on four citric acid cycle metabolites — citrate, glucose, lactate, and pyruvate — we found higher concentrations of both citrate and glucose in patients compared with controls after correcting for age, sex and body mass index, but only the difference in CSF citrate survived correction for multiple comparisons. Within the patient group, CSF citrate concentrations were higher among lithium users than non-users. In conclusion, this report adds further evidence for a mitochondrial dysfunction in bipolar disorder.

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 it
