Abstract
This scientific commentary refers to ‘Hyperphosphorylated tau in patients with refractory epilepsy correlates with cognitive decline: a study of temporal lobe resections’, by Tai et al. (doi:10.1093/brain/aww187) . Temporal lobe epilepsy (TLE) is the most frequent focal epilepsy in adults. The epileptogenic network responsible for seizures encompasses multiple limbic structures including the hippocampus and neighbouring cortices. The histomorphological hallmark of TLE is mesial temporal sclerosis, described originally in post-mortem studies as neuronal loss and gliosis in the hippocampus, entorhinal cortex and amygdala. About a third of patients do not respond to anti-epileptic medication despite continued development of new molecules. Drug-resistant TLE is a serious chronic condition associated with high risk for psychosocial impairment, cognitive decline and mortality. In these patients, surgery is currently the only therapeutic solution to reduce the seizure burden and, in many instances, cure the epilepsy. MRI has been instrumental in TLE surgery by allowing the in vivo detection of neuronal loss and gliosis as indexed by hippocampal atrophy on T1-weighted MRI and increased signal in T2-weighted images. In this issue of Brain , Tai and co-workers provide compelling evidence that long-standing epilepsy is associated with tauopathy, providing a basis for conceptualizing TLE, and possibly all epilepsies, as neurodegenerative disorders (Tai et al. , 2016). In the strictest sense, neurodegeneration refers to pathology affecting neuronal structure and consequently function. In practice, neurodegenerative diseases form an ensemble of conditions with heterogeneous pathological …

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
