South Wales Joint Neuroscience Meeting, Bridgend, 29 April 2010: a 66-year-old man who suddenly couldn't drive
Bibliographic record
Abstract
A 66-year-old man was referred by his general practitioner following an event in October 2009. During his weekly trip into town he had attempted to drive his car but found that he was unable to operate the controls. Nor could he work the gear stick, or apply or release the handbrake. His wife, who witnessed this episode, added that he was unable to navigate and to follow the route when a passenger in the car took over driving. His power, movements and speech were not affected. One hour later, after he had returned home, he was oriented in space and time but was still not felt to be back to normal in terms of speed and clarity of thought. For several weeks before this episode his wife had noticed that his concentration and ability with daily activities and domestic tasks had deteriorated. On one occasion he had forgotten to put out the recycling bin on the appointed day of the week and he forgot the usual cleaning routine at home, behaviour that was uncharacteristic. Several days before the event he had complained of a mild headache, described as an ache behind the eyes, which had been worse in the mornings. There was no history of fever, sweats, weight loss or other systemic symptoms. There was a past history of hypertension and hypercholesterolaemia. He was an ex-smoker with a 40 pack-year history. Initial examination revealed a blood pressure of 171/100 mm Hg but otherwise systemically he was normal. He was alert and oriented in time and place. He had normal visual acuity and eye movements. There was a left lower quadrantanopia, left-sided visual neglect and cortical sensory loss in the left hand (agraphaesthesia and astereognosis). There was no evidence of constructional or dressing apraxia or of visual agnosia. Language and other …

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.
