RESUMO
PURPOSE: The study aimed to describe the electroclinical features of ictal kissing, an unusual behavior that may occur during focal seizures. METHOD: Twenty-five patients collected from four epilepsy centers and previously published reports were reviewed for their demographic, clinical, and electrophysiological features. RESULTS: Sixteen of 25 patients were female. The mean age was 32.9 years (9.9-51 years) and the average age at seizure onset was 14.5 years. All seizures were localized to the temporal lobe (TL) and lateralized to right side in 17 patients, left side in 2 patients, and unclear in 6 patients. A total of 55 ictal video electroencephalograms (EEGs) were analyzed. There were other symptoms such as speaking, spitting, hugging, and oral and upper-extremity automatisms along with different types of ictal kissing behavior during the seizures. The median duration of all seizures was 106.7±73.73s. Kissing occurred at a median time of 71s (1-95s) after the onset of seizure, and ictal epileptiform discharges usually involved TL during kissing episode. CONCLUSION: Ictal kissing is mainly associated with right TL and female gender, although association with left TL may also occurs, possibly related to the circuits involving temporo-insular structures.
