This communication is based on a study of twenty cases of skull injury, four previously reported and sixteen comprising the present series.
Foerster,1 Wartenberg2 and especially Schwab3 were the first to demonstrate abnormal encephalographic conditions in patients who had sustained skull injuries. Later, Heidrich,4 Bielschowsky,5 Pancoast and Fay,6 Foerster and Penfield,7 Frazier and others reported similar observations. In a paper on encephalography I included four cases of the posttraumatic state with abnormalities in the encephalogram.8 Since then I have had the opportunity of observing sixteen additional cases of skull injury, the encephalographic conditions in which are reported in this communication.
