title: [Relation between the EEG image and the damaged area in cerebrovascular diseases].
abstract: The author tried to establish the value of EEG investigations in the cases of cerebrovascular diseases of ischaemic type, mainly in relation to the site of damage. EEG investigations were carried out in 200 cases divided into 4 groups of 50 patients in each according to the location of the lesion. The sites of the lesions were in group I in the internal capsule, in group II in the cortex, in group III disseminated foci were situated in both cerebral hemispheres, in group IV in the brain stem. On the basis of EEG investigations certain tendencies were established differentiating these groups: in group I mostly episodic changes were found on the side of damage, in group II intensive focal changes prevailed, in group III changes of background activity were the most frequent finding, in group IV usually bilateral episodic changes were usually present. The obtained results point out that EEG may be of some use helping the clinician in recognizing the site of the lesion and in establishing the prognosis.
