Abstract

fetched live from OpenAlex

Visual hallucination is very common in case of delirium and other neuropsychiatric disorders. It is one of the most common clinical symptoms for which psychiatric consultation is requested on medical floors. When hallucination dominates the clinical presentation, a patient may be misdiagnosed as suffering from a psychiatric disorder. This case is a wonderful example of Peduncular Hallucinosis, an underlying organic pathology. A possible pontine tumor was discovered in a patient admitted to the medical floor with altered mental status in the absence of any focal neurological signs. doi: http://dx.doi.org/10.4021/jmc868w

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
