[Occurrence of triphasic waves in two cases of thyrotoxic crisis (author's transl)]

An electroencephalogram taken on two patients suffering from a thyrotoxic crisis, showed the presence of typical triphasic waves. This pattern was first described in 1950 by Foley et al., who believed that it occurred specifically in patients with hepatic encephalopathy. Since then, however, it has been shown that triphasic waves can be identified in other (e.g. renal) metabolic brain diseases and, less commonly, in a variety of either organic or functional cerebral disorders.
