Post-anoxic theta and alpha pattern coma.
Theta pattern coma is a rare EEG finding, described in the course of post-anoxic or post-traumatic coma and interpreted as a "malignant" variant of alpha pattern coma. A case of isolated theta pattern coma, followed by alpha pattern coma is reported. Short temporal succession of such patterns would seem to confirm the hypothesis of a close relationship between them. Possible physiological mechanisms involved in the generation of the patterns are discussed.
