Development and Validation of a Peripheral Cell Ratio and Lactate Score for Differentiating Status Epilepticus from Prolonged Psychogenic Non-Epileptic Seizures.

Lactate levels peak early post-SE, whereas cell counts and ratios do so later. The differing post-event time profiles of lactate levels versus neutrophil count, SIRI and SII allows incorporation into three separate scores which can assist in differentiating SE from pPNES.
