TI  - Assessment of hairline EEG as a screening tool for nonconvulsive status 
      epilepticus.
PG  - 959-65
AB  - PURPOSE: Because of the high incidence of nonconvulsive status epilepticus 
      (NCSE), the attraction of a "quick and easy" screening electroencephalogram (EEG) 
      is obvious. Previous studies have shown utility of hairline EEG in diagnosing 
      epilepsy. However, this technique has not been evaluated as a screening tool for 
      NCSE. We wanted to provide proof of principle that a screening hairline EEG has 
      sufficient sensitivity to use as a screening tool for diagnosing NCSE. METHODS: A 
      total of 120, 2- to 3-min EEG samples of normal and various abnormal digital EEG 
      studies were reformatted in three six-channel montages (A, longitudinal bipolar; 
      B, referential to ipsilateral ear; C, referential to contralateral ear) that 
      mimicked a hairline recording and were interpreted by five neurophysiologists. 
      The test data interpretation was compared with the original EEG interpretation. 
      RESULTS: Performance was best with montages A and B; 71% and 70.5% of the samples 
      were interpreted correctly by using these montages. Only 65% of the samples were 
      correctly interpreted by using montage C. With the best montage (A), the 
      sensitivities ranged from 91% for normal EEG to 54% for periodic lateralized 
      epileptiform discharges (PLEDs). The sensitivity for seizures was only 72%. 
      Seizures were frequently misinterpreted as more benign patterns such as normal 
      and diffuse slowing. CONCLUSIONS: EEG data reformatted to resemble a hairline EEG 
      had low sensitivity for detecting seizures. As a result, we do not recommend 
      further pursuit of hairline EEG as a "quick and easy" screening tool for NCSE.
