In the medical literature, the term of "new-onset refractory status epilepticus" (NORSE) is a novel term. Herpes Simplex Virus-1 and other viral infections can be cause to NORSE. Seizures are a rare sign of HSV encephalitis, but they can occur as the first symptom. Herein, we present a case of NORSE triggered by HSV-1 encephalitis, which had been diagnosed via cerebrospinal fluid polymerase chain reaction (PCR) method and magnetic resonance imaging findings.
