Periodic Lateralized Frontal Epileptiform Discharges with Ipsilateral Epilepsia Partialis Continua
Bibliographic record
Abstract
PURPOSE: Lateralized clonic jerks of the extremities during epileptic seizures usually arise from the contralateral rolandic cortex. In our exceptional case one-sided extremity twitches related to epileptiform activity in the ipsilateral frontal lobe. METHODS: Case study with clinical-electroencephalographic correlation. RESULTS: A 47-year-old man suffered destruction of most of his right cerebral hemisphere, including the perirolandic region. Epilepsia partialis continua (EPC) ensued, with clonic jerks of the proximal right upper and lower limbs temporally related to periodic lateralized epileptiform discharges (PLEDs) from the parasagittal region of the right frontal lobe with a variable time interval over 100 ms. Sectioning of the subcortical callosal and projection connections of the frontal lobe abolished the clonic jerks. CONCLUSIONS: We propose the ipsilateral EPC arose from projections from the supplementary motor region to the medullary reticular formation to account for the long and variable latency between PLEDs and jerks.

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.
