Abstract

Alpha coma is a coma state with predominant alpha activities in electroencephalography. There are two different patterns of alpha coma, depending upon the distribution of alpha activity. The causes may vary with the distribution pattern. To clarify the difference in alpha-activity distribution, we conducted current-source analysis of the alpha-frequency band in two patients with alpha-coma caused by drug intoxication and pontine infarction, respectively. The current-source analysis of alpha-frequency bands may make it easier to distinguish the distribution patterns.
