Episodic nausea and abdominal sensations as sole manifestations of simple partial seizures

In adults, seizures manifesting with abdominal complaints are usually associated with complex partial or secondary generalized seizures. Also, seizure periodicity is not expected in postmenopausal women. We encountered a 72-year-old woman with episodic nausea and abdominal pain that usually occurred with predictable regularity. When symptoms persisted after extensive gastrointestinal investigations and cholecystectomy, she was referred to us and the diagnosis of simple partial seizures was suspected. Both EEG and brain MRI were normal. The diagnosis was established by video/ EEG monitoring, which recorded several typical clinical events associated with right temporal ictal discharges. Because treatment with several antiepileptic medications caused intolerable side effects, the patient is now maintained on a low dose of Lamotrigine, which reduced seizure frequency and severity. This patient demonstrates that "abdominal" complaints, although rare, may be the sole manifestation of simple partial seizures. Unless considered in the differential diagnosis, the patient may undergo unnecessary and potentially harmful procedures

Tiagabine induced non-convulsive status epilepticus in a patient without history of epilepsy

Cases of non-convulsive status epilepticus [NCSE] induced by tiagabine [TGB] were occasionally reported. Almost all had a prior history of epilepsy. We describe here, the clinical and EEG findings in a patient, without history of seizures, who after the start of TGB developed NCSE. A 53-year-old man with history of paranoid schizophrenia, presented with "alteration of his mental state". Three weeks early, TGB was added to his psychiatric regimen. On the second day of admission, he became unresponsive with a blank stare. Concomitant EEG showed abundant sharp and slow wave complexes. The episode lasted for 4 hours and was aborted by the intravenous administration of lorazepam. The TGB was discontinued without recurrence of subsequent seizure activity. This case supports the contention that TGB can induce NCSE in subjects not previously known to have seizures
