Ictal whistling: a rare automatism during temporal lobe seizures.

One of the most unusual ictal automatisms reported is whistling. Two patients, both males, are described who had prominent whistling as a component of their complex partial seizures. Both had temporal lobe epilepsy with resolution of seizures after a temporal lobectomy. Ictal whistling appears to localize to the temporal lobe but may not be useful for lateralization.

Automatisms with preserved responsiveness and ictal aphasia: contradictory lateralising signs during a dominant temporal lobe seizure.

The 25-year-old right-handed woman suffering from temporal lobe epilepsy (TLE) was referred to our centre for presurgical evaluation. MRI showed a right-sided hippocampal sclerosis. During video-EEG-recorded seizures, abdominal aura was followed by oral automatisms, during which she was completely reactive to external stimuli, although she was unable to speak. Ictal EEG showed right temporal seizure pattern, without contralateral propagation. She had abnormal speech postictally. Speech-activated functional transcranial Doppler sonography revealed right-sided speech dominance. She has become seizure free after a right-sided amygdalo-hippocampectomy. In our patient, contradictory clinical ictal lateralising signs (automatisms with preserved responsiveness vs. ictal and postictal dysphasia) occurred during right-, speech-dominant-sided seizures. This is the first report when automatisms with preserved consciousness occurred during a seizure originating and involving the speech-dominant hemisphere.

UNLABELLED: Epileptic seizures are followed by dynamic alterations in neurologic function in the postictal period which have received little attention by clinicians over a long period of time. We therefore retrospectively studied videotapes of 160 patients with focal epilepsy who underwent presurgical evaluation, for the occurrence of postictal symptoms to determine whether these phenomena have any localizing or lateralizing value in defining the seizure onset zone. RESULTS: (1) We found postictal paresis in 22 of 160 patients (18.8%) in each case contralateral to the hemisphere of seizure onset. (2) 'Perservative' automatisms which start during the ictus and continue in the postictal period occurred in 25.2% of 135 patients with temporal lobe epilepsy but not in patients with frontal lobe epilepsy. (3) Sexual automatisms defined as manipulations of the genitals were found exclusively in patients with temporal lobe epilepsy (in 5.9% of 135 patients). (4) Postictal 'Nose-wiping' was evident in 51.3% of 76 temporal lobe epilepsy patients but only in 12.0% of 25 extratemporal lobe epilepsy patients and was performed with the hand ipsilateral to the hemisphere of seizure onset in 86.5% of all temporal lobe seizures. (5) Postictal language disturbances were observed only in patients with temporal lobe epilepsy (34% of 97 patients) and pointed to a seizure onset in the dominant hemisphere in 80.8%. We conclude that postictal phenomena can provide reliable information for the localization of the seizure onset zone in patients with complex partial seizures. Thus, more attention should be given to the postictal state during presurgical epilepsy monitoring.
