OLIVEIRA-SOUZA, R. et al. Persistent alpha-vegetative state. Arq. Neuro-Psiquiatr. [online]. 1989, vol.47, n.2, pp.212-223. ISSN 0004-282X.

After briefly reviewing the concepts of «coma» and «alpha-coma», we report the case of a patient with presumable Pick's disease who spent several weeks in a vegetative state with a normal and reactive EEG in the alpha range in the later stages of her illness. We (a) emphasize some implications of the appearence of the eyes in such patients, b) stress the importance of distinguishing alpha activity from true alpha rhythm and (c) suggest the category «alpha-coma» should include only those individuals bearing evidence of disorders of the junctional tegmentum of the pons and midbrain. In a complementary way, we propose that patients in a persistent vegetative state displaying normal EEG should be separately classified as persistent «alpha-vegetative state».
