[Electro-encephalographic study in 25 patients with Creutzfeldt-Jakob's disease (author's transl)].

Standard EEG tracings were recorded in 25 patients with anatomically confirmed Creutzfeldt-Jakob's disease. A total of 82 recordings were studied, and were found to conform with those previously described. More particularly, the periodic paroxystic tracing described by Nevin in 1954 was observed in 16 cases, but these were of late onset, frequent, and non-specific. By adopting the anatomical classification described by Daniel (1972), the authors were able to obtain some evidence of electro-anatomical correlations in some cases, but confirmation by means of a larger series of patients is necessary.
