Abstract

fetched live from OpenAlex

BACKGROUND: There is growing evidence that the cerebellum serves an important role in controlling affect and cognition, and its pathology has been implicated in several psychiatric disorders. Furthermore, the brainstem's role in cognition and affect has been historically overlooked. Neuroimaging studies and an increasing number of case reports indicate cognitive deficits and hallucinatory phenomena after isolated brainstem lesions. CASE PRESENTATION: We report a 56-year-old man who developed persistent persecutory delusions, hallucinations, cognitive impairment and flattened affect following an extensive bilateral cerebellar stroke with involvement of the midbrain. CONCLUSIONS: This is one of the few reported cases of unremitting psychosis secondary to cerebellar and mesencephalic vascular infarction. We suggest, based on the distribution of the patient's lesions, that his corresponding symptoms are a result of a disruption to cerebrocerebellar pathways. This article briefly reviews recent pathophysiological explanations behind the psychosis associated with brainstem and cerebellar lesions, the treatment, as well as the relation of these structures to each other.

Full frame distilled prediction

Teacher imitation

Not 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.
