  • Title: 'alpha pattern coma' following cerebral anoxia.
    Author: Alving J, Møller M, Sindrup E, Nielsen BL.
    Journal: Electroencephalogr Clin Neurophysiol; 1979 Jul; 47(1):95-101. PubMed ID: 88365.
    Abstract:
    In 30 patients, who were all comatose as a result of cerebral anoxia after cardiac arrest, at least one EEG with activity in the alpha frequency range was recorded. Regionally the activity of the above mentioned characteristic was often diffusely distributed or most pronounced occipitally, whereas a tendency to affect other regions was rarely observed. In 50% of the patients, where more than one EEG was recorded, the 'alpha' rhythm was still present in the following record. Only one of the patients survived, and even so, with considerable mental defects. In 4 patients the level of consciousness improved, but 3 of them never reached a definite level of cortical function and died as a result of cerebral anoxia.
