Summary
Summary. Continuous brain blood supply in healthy individuals is warranted by brain autoregulation, the borders of which are not completely strict and can be changed as a part of dynamic physiological control. In acute neurological diseases like hypertensive encephalopathy, brain infarction, intracerebral hemorrhage and subarachnoid hemorrhage, a great attention should be paid to cerebral perfusion pressure preservation (which represents a difference between mean arterial pressure and intracranial pressure) when blood pressure is regulated. To preserve neurological function it is necessary to know anatomic and pathophysiological qualities of brain circulation and to approach the treatment of hypertension. In case of ishemic stroke hypertension should be reduced gradually, through several days, having in mind the distance of ischemic penumbra. The ideal antihypertensive for the reduction of hypertension in acute neurological diseases should have the following characteri- stics precise value and time control of blood pressure, not to have a rebound-phemonenon, not to cause the effect of exceed- ing with initially severe hypotension, not to have impact on heart muscle and not to worsen intracranial pressure. In everyday clinical work with these patients one should act according to the instructions for management of patients with stroke prepared by the Croatian Society for Neurovascular Disorders of the Croatian Medical Association and the Croatian Society for the Prevention of Stroke
