Phantom bedside intruder in Parkinson's disease
Bibliographic record
Abstract
Abstract Psychosis is a known neuropsychiatric feature in Lewy body disease. While visual hallucination remained the most common form of psychosis, a minor proportion of patients suffer from multimodal psychosis in Parkinson's disease (PD). However, current research does not always specify whether multimodal psychosis is manifested in an independent, sequential, or concomitant manner. As such, studies addressing brain–behavior relationship of multimodal psychosis remain sparse. In this paper, we described a case of PD multimodal psychosis manifesting as a phantom bedside intruder, where the patient episodically “felt” the presence and “heard” the breathing sound of the “person” without visualizing him. [18F]fluorodeoxyglucose‐positron emission tomography scan showed predominant hypometabolism in brain regions involving the bilateral insula, superior temporal gyrus, supramarginal gyrus, and anterior cingulate. The unusual multimodal phantom bedside intruder phenomenon observed in this case is likely a result of combinational dysfunction of bilateral temporal parietal lobes.

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.
