Created by Derry and colleagues , the item FLEP scale is designed to aid clinicians in distinguishing frontal lobe seizures from parasomnias. While polysomnography is considered the gold standard approach for differentiating the two conditions, scale developers cite the need for an efficient, cost-effective alternative for those who, for whatever reason, do not have access to sleep clinic facilities. In order to distinguish nocturnal events caused by epilepsy from those related to parasomnias, the scale queries several factors, including: age of onset and event duration, frequency, timing, symptoms, stereotypy, and recall.

Our investigation highlights the inadequacy of some of the items in the scale. The item investigating wandering, as presently formulated, may be unable to distinguish nocturnal wandering from sleepwalking.
The items about "recall" and "clustering" of the events throughout the night may increase the likelihood of mistaking RBD for seizures. Further testing of the reliability of the FLEP scale items appears to be needed.

Frontal Lobe Epilepsy and Parasomnias (FLEP) Scale
Clinical features that may be useful in distinguishing nocturnal frontal lobe epilepsy NFLE from parasomnias. These features were included in the scale based on their discriminatory value. Frequencies of Frontal Lobe Epilepsy and Parasomnias FLEP scale scores generated by the nonmedically trained interviewer, color-coded according to actual diagnosis. Of the 62 patients interviewed, 3 had their conditions incorrectly diagnosed using the scale; these were all patients with parasomnias who generated low positive scores.
