AB  - Triphasic waves (TWs) are a distinctive, although non-specific EEG pattern, which 
      are quite frequently encountered and sometimes difficult to interpret. Although 
      initially considered pathognomonic of hepatic encephalopathy, TWs have been 
      described in association with a large number of conditions. TWs may occur in 
      encephalopathies (metabolic or structural) or as an ictal pattern. Nonepileptic 
      TWs with sharply contoured morphology may resemble epileptic patterns encountered 
      in nonconvulsive status epilepticus (NCSE), thus leading to misinterpretation and 
      overinterpretation of this pattern as ictal, if only the EEG is considered. An 
      electroclinical response to benzodiazepines and the evaluation of consciousness 
      impairment should be considered when interpreting TWs. Evaluating only the EEG 
      without considering also clinical and laboratory findings is not only useless and 
      meaningless, but may even lead to serious consequences.
