Proceedings: Electroencephalographic studies on stroke in stroke-prone SHR. (2). Approach to stroke.

Abstract

SHRSP with signs and symptoms of cerebral stroke showed marked abnormalities in cortical EEG and during drowsiness; laterality in EEG was manifested more remarkably.Especially, lateralities in spindle-like activity (lazy activity), which were frequently observed in SHRSP over 8-month-old (during wakefulness, they often showed diffuse slow α or diffuse θ pattern EEG), were defected in 5-month-old SHRSP with blood pressure of over 200-220mmHg.These findings suggested that any functional change in the brain prior to increased cerebrovascular permeability might occur, and that there are the possibilities for further electroencephalographical studies to throw light on the predictive detection of cerebrovascular involvement in hypertension.
