periictal water drinking localizes as does kissing epilepsy

The authors describe seven patients with medically refractory temporal lobe epilepsy whose seizures were associated with peri-ictal water drinking behavior. Presurgical evaluation, including video-EEG monitoring, MRI, SPECT, and neuropsychological testing, revealed a seizure onset in the nondominant temporal lobe. All patients had an excellent outcome after epilepsy surgery. Peri-ictal water  drinking may represent a lateralizing sign indicating seizure onset in the nondominant temporal lobe.

Ictal kissing is a release phenomenon in nondominant temporal lobe epilepsy. 3 patients with ictal kissing were all righthanded women with longstanding right TLE.  Its occurrence to environmental cues suggests its a release phenomenon rather than an ictal event
