Abstract
OBJECTIVE: To investigate commonalities in the clinical presentation of melancholia over time. METHOD: I conducted a comparative study to 2 epidemiologically complete databases from 1875-1924 and 1995-2005. RESULTS: Patients in the historical period (1875-1924, compared with 1995-2005) with a diagnosis of melancholia show a classic profile of endogenous onset, with remission after 6 months, neurovegetative features, and, commonly, psychosis. The incidence of psychotic presentations appears to have fallen in recent decades. Patients in the contemporary period (1995-2010, compared with 1875-1924) at first admission for severe depressive disorders are more likely at an older age, more likely to go on to die by suicide, and will have much more frequent admissions. CONCLUSIONS: The data from this study support classical perceptions of melancholia. The poor outcomes in contemporary cases of severe depressive disorders support arguments for distinguishing between melancholia and other depressive disorders.

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.
