Does Schizoaffective Disorder explain the mental illnesses of Robert Schumann and Vincent Van Gogh?
Bibliographic record
Abstract
The geniuses Robert Schumann and Vincent Van Gogh show striking similarities both in the longitudinal nature of the progression of their illnesses, and the symptoms they experienced. There have been physiological explanations posed for both men, including Meniere's disease, tertiary syphilis, acute intermittent porphyria, terpenoid and lead poisoning, intracranial masses, temporal lobe epilepsy and dementia caused by vascular hypertension. The evidence for these physiological explanations is assessed. Schizophrenia and Bipolar disorder have also both been postulated to explain the symptoms of the two men, but neither man perfectly fits the diagnostic criteria for either. Schizoaffective disorder is a term used to describe patients who experience symptoms from both the psychosis of Schizophrenia and the mood disorders of Bipolar disorder. This paper aims to explain why Schizoaffective disorder explains the symptomology of these men better than either Schizophrenia or Bipolar disorder does alone. Schizoaffective disorder, however, did not exist as a diagnosis when Van Gogh and Schumann were alive, and so was not considered by their physicians.

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.
