Abstract
Cerebral dysfunctions leading to an impaired level of consciousness are always associated with EEG changes. A comatose state can be caused by different types of injury. Apart from severe diffuse damage in both hemispheres, often only circumscribed lesions in the brain stem lead to a loss of consciousness (Plum and Posner, 1980). A vast amount of literature already exists regarding EEG changes in coma (e.g., Arfel, 1975; Bauer, 1987; Bergamasco et al., 1968; Chatrian, 1975; Loeb, 1958; Rumpl, 1987; Rumpl et al., 1979; Silverman, 1963). In the literature the discussion and interpretation of the correlations between the degree of impaired consciousness, neuropathological, and EEG findings is rather contradictory. Regarding the EEG only a few studies are based on neuropathological findings.
