case_images: (a) The patient is standing and tilts her head on the right side (first mark) while hyperextending her back and neck. At the end of the stretching action (second mark), high amplitude slow-wave 2.5 Hz activity appears in the right hemisphere, lasting 6 to 7 seconds and mainly involving the frontotemporal areas. The ECG shows mild sinus tachycardia. (b) The patient is seated and tilts her head on the left side (first mark) while hyperextending her back and neck and stretching backward the ipsilateral arm. At the end of the stretching action (second mark), high amplitude 2 Hz slow-wave activity appears in the left hemisphere, lasting 7 to 8 seconds, mainly involving the frontotemporal areas and spreading to the contralateral homologous regions. The ECG shows mild sinus tachycardia. (c) The patient is standing and tilts her head on the right side (first mark) while hyperextending her back and neck backwards. Concomitantly to the end of the stretching action (second mark), the EEG trace shows a generalized high amplitude 2.5 Hz slow-wave activity lasting 9 to 10 seconds, more evident in the right frontotemporal regions.

case_images: During the episodes, EEG showed bursts of monomorphic, slow-wave activity (2-3 Hz), lasting from 3 to 12 seconds, predominant on the frontotemporal regions and mainly ipsilateral to the side of the head tilt (Figure 1a and Figure 1a and Figure 1a and Figure 1a and Figure 1a and Figure 1a and 1b), less frequently diffuse (1b), less frequently diffuse (1b), less frequently diffuse (1b), less frequently diffuse (1b), less frequently diffuse (1b), less frequently diffuse (Figure 1c).
