      Complex Partial Status Epilepticus.

AB  - The diagnosis of nonconvulsive status epilepticus (NCSE) largely relies on 
      electroencephalography (EEG) findings, but the existing diagnostic criteria for 
      EEG results are sometimes inconsistent. Much debate has centered on periodic 
      epileptic discharges (PEDs) and their relationship with seizures. The recently 
      published Salzburg Consensus Criteria for diagnosis of NCSE, which consider PEDs 
      to be ictal findings under several conditions, have been proven to have high 
      diagnostic accuracy. However, the criteria do not include periodic slow waves 
      (PSWs) and do not consider these as overall ictal electrographic changes. Here, 
      we report 2 cases of complex partial status epilepticus in which routine EEG 
      showed PSWs without epileptiform activity during the clinical ictal phase. Both 
      patients were elderly males who had histories of seizures and presented with 
      impaired consciousness and signs such as aphasia or tongue automatism that 
      indicated a temporal lobe origin. After we administered antiepileptic drugs 
      (AED), the clinical signs and periodic EEG slow waves disappeared. These cases 
      show that PSWs may appear as ictal electrographic changes in NCSE. When PSWs 
      accompany clinical signs suggestive of NCSE, they should be considered ictal 
      findings, and physicians should administer AED.
