THE VARIOUS reports which have appeared in the literature dealing with the electroencephalogram in cerebrovascular disease and in hemiplegia have stressed the fact that a high percentage of these electroencephalograms recorded while the patient is awake are normal. Cohn, Raines, Mulder and Neumann1 reported on 104 patients with thrombosis, embolism or hemorrhage involving the cerebral vessels. Many of these patients had electroencephalograms which returned to normal with stabilization of the clinical findings, the younger patients showing a greater tendency for this to occur. The electroencephalographic change noted was the presence of slow waves, either general or on the side of the involved hemisphere. These investigators also found that cortical damage gave rise to more slow activity than did subcortical lesions of equal size. They found that factors other than age which influenced the return of the electroencephalogram to normality were the site and the amount of cerebral damage. Cress
