Localization of ictal pouting in frontal lobe epilepsy: A case report
Ictal pouting (IP), which mimics expressions of fear, displeasure, or disgust, appears frequently during focal seizures. IP is described as an inverted smile. It consists of a turned-down mouth with puckering of the lips and symmetrical sustained (> 5 s) lowering of the labial commissures, commonly accompanied by contraction of the chin.

Sep 5, 2016 · The chapeau de gendarme or ictal pout sign is characterized by a turned-down mouth produced by bilateral lip and chin contraction. This term gives reference to the shape of the gendarme's hat seen during Napoléon I's time. If seen early, it …
Localisation in focal epilepsy: a practical guide
The ‘chapeau de gendarme’ or ictal pout sign is characterised by a downturned mouth from bilateral lip and chin contraction.38 If seen early in the seizure it is highly localising to frontal lobe onset, in particular anterior cingulate, orbitofrontal region or …

Dec 20, 2022 · Ictal pouting has been described as a sign of seizures originating in the frontal lobe, especially in the anterior cingulate 1 or anterior insular cortices, 2 areas uninvolved in our patient's seizures.

Dec 14, 2020 · Ictal onset, characterised by a burst of polyspikes that originated from the right superior frontal sulcus (SFS), was followed by LVFA rapidly involving the right medial region of the superior frontal gyrus, anterior-middle cingulate, and anterior insular cortices before the emergence of CDG (Fig. 2B). Figs.

One localizing sign that has been purported for frontal lobe epilepsy (FLE) is a characteristic down turning of the mouth into a deep frown, known as ictal pouting or ‘chapeau de gendarme’ (CdG) sign.

Nov 29, 2018 · Ictal pouting (Chapeau de gendarme sign) is a distinct seizure semiology that can often be overlooked and coexist with focal cortical thickening. We suggest that focal cortical dysplasias should be searched in patients with ictal pouting particularly in …
Neural network underlying ictal pouting ("chapeau de …
In order to determine the anatomical neural network underlying ictal pouting (IP), with the mouth turned down like a "chapeau de gendarme", in frontal lobe epilepsy (FLE), we reviewed the video-EEG recordings of 36 patients with FLE who became seizure-free after surgery.
Ictal pouting, also known as the chapeau de gendarme sign, is an easily recognizable facial expression with its origins in the frontal lobe, seen early on in frontal lobe seizures.
Neural network underlying ictal pouting - Epilepsy & Behavior
Ictal pouting is a characteristic facial expression observed in frontal lobe seizures. Main-associated clinical features point to the anterior cingulate cortex (ACC). SEEG and FDG-PET data suggest involvement of both ACC and insula. Ictal semiology allows differentiating rostroventral and dorsal ACC involvement.
