Recent studies have demonstrated that intramuscular administration of thyrotropin-releasing hormone (TRH) or its analogue improves various clinical aspects of intractable epilepsy such as Lennox-Gastaut syndrome, West syndrome, and myoclonus epilepsy. Other clinical studies reported efficient property of intravenous TRH against status epilepticus. However, it is also true that intravenous TRH produces epileptic seizures in patients with epilepsy or organic brain damage. ⋯ With 50 mg/kg of TRH, the exaggerated seizure patterns were followed by marked suppression of electroclinical seizures. 50 micrograms of i.c.v. TRH (n = 5), like higher doses of i.v. TRH, caused a slight, but not a significant, build up of electroclinical ictal seizures, beginning immediately after the injection and lasting for about 30 min.(ABSTRACT TRUNCATED AT 250 WORDS)
