Abstract

fetched live from OpenAlex

We report a 42-year-old woman who presented with cluster headache (CH) in association with other neurological symptoms as the index event of new onset multiple sclerosis (MS). Her initial symptoms were left-sided headache with ipsilateral lacrimation and nasal congestion associated with ipsilateral facial numbness. A subsequent similar headache attack was also associated with ipsilateral arm ataxia and gait ataxia. She had many additional short headache attacks without focal neurological symptoms. Her cluster-like headache attacks have not recurred since intiation of dimethyl fumarate. Our patient illustrates that cluster-like headache attacks can occur as a first symptom of MS, in our patient in association with other neurological symptoms. A striking finding in our patient was a large demyelinating lesion in the brachium pontis ipsilateral to the headaches, although additional supratentorial demyelinating lesions were also present. Although CH associated with MS is rare, our patient and the two other reported patients with MS and CH with similar ipsilateral brachium pontis lesions suggest that the lesions in this location may have played a role in the generation of the cluster-like attacks.

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.
