WebFindings of EEG previously reported in a few patients with DLB 6-11 suggested that in addition to generalised slowing, sharp or triphasic waves may be characteristic features useful in clinical diagnosis. There are pragmatic reasons to predict focal EEG abnormalities of the temporal lobe in DLB. WebThe common association of triphasic waves (TWs) with hepatic encephalopathy has been known since early descriptions of this EEG phenomenon.1-23 In fact, Reiher (1970)4 concluded that TWs fulfilling several morphological criteria were pathogno monic for hepatic coma. However, TWs have been found with
