Epileptic Disorders
MENULet's all repeat – palilalia may be epileptic! Volume 24, issue 1, February 2022
Video-scalp EEG shows one electroclinical seizure featuring palilalia (sensitivity: 7 uV/mm, LF: 1 Hz, HFF: 70 Hz, notch off). There was a behavioral change (blue star) before he started hyperventilating and experiencing palilalia (red star). He was able to follow a simple command during the seizure. Electroencephalographically, there was rhythmic 4-6 Hz, sharply contoured activity in the bitemporal chains (red arrows) followed by evolution in morphology, amplitude, and location.

RH: right hippocampal contacts; RF: right frontal contacts; LH: left hippocampus contacts. During the left hippocampal electroclinical seizure, there was hyperventilation (blue star) followed by palilalia (yellow star). Electroencephalographically, there was ictal onset at the left hippocampus (LH; red arrow) with subsequent spread to the right hippocampus (RH; blue arrow) and then right frontal region (RF; pink arrow).
