ABSTRACT

Objectives: identify the relationship between electroencephalographic alterations and initial cerebrovascular lesions among neurologically asymptomatic hypertensive patients using the GTE scale.
Methods: magnetic resonance (0.35 Tesla, T1, T2, FLAIR) and 19-channel electroencephalogram images were obtained from 49 asymptomatic hypertensives, who were divided into three groups: A, without cerebrovascular lesion; B, with non-classical cerebrovascular lesion; and C, with classical ischemic cerebrovascular lesion.
Results: group C showed higher mean values on the GTE scale (4.42) than Groups B (3.36) and A (2.63), with a significant difference in the median for each group (p=0.03).
Conclusion: the electroencephalographic alterations found in the patients studied are associated with cerebrovascular changes induced by arterial hypertension. The GTE scale is a simple method which could be used for the screening of subclinical cerebrovascular lesions among hypertensive patients.
