[The value of EEG and computertomography in ischemic stroke (author's transl)]

35 patients with ischaemic cerebrovascular disease were investigated using EEG and computertomography on the same day and the results from both investigations were compared. The EEG was pathological in 27 cases of which 26 showed focal changes and one case generalised changes. In 8 patients the EEG was normal. The CT-results showed a hypodense lesion in 17 patients and multiple hypodense lesions in 3 patients. 13 cases had atrophy and a normal CT was present in 2 cases. In 26 patients the EEG and CT results were both pathological and in one case both normal. In the diagnosis of ischaemic cerebrovascular disease both of these noninvasive investigative techniques complement each other; CT demonstrating the morphology of a lesion whilst EEG shows more functional changes in the brain.
