Arterial hypertension: possible pathogenetic mechanisms for the development of chronic brain ischemia


Professor E. Barinov, MD; T. Faber; V. Sokhina M. Gorky Donetsk National Medical University,

Arterial hypertension is considered as a risk factor for the development of chronic cerebral ischemia (CСI) but the causes of this phenomenon remain poorly understood. Due to the role and interaction of the sympathoadrenal and renin-angiotensin systems of the body in impaired function of the «vessel-glia-neuron» system is discussed. The review presents facts regarding the features of adrenergic regulation of cerebral circulation, the possible participation of adrenoreceptors in cognitive impairment and the development of neuroinflammation. The relationship of angiotensin-2 with remodeling of the vascular wall and the permeability of the blood-brain barrier, activation of glial cells is considered. These data substantiate the need to study selective agonists of α-, β-adrenergic receptors and blockers of AT1 receptors for the treatment of patients with cerebrovascular disorders.
