Cerebral atherosclerosis is a type of atherosclerosis where build-up of plaque in the blood vessels of the brain occurs. Some of the main components of the plaques are connective tissue, extracellular matrix, including collagen, proteoglycans, fibronectin, and elastic fibers; crystalline cholesterol, cholesteryl esters, and phospholipids; cells such as monocyte derived macrophages, T ...
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries.This is a chronic inflammatory disease involving many different cell types and driven by elevated levels of cholesterol in the blood. [9]
The histologic findings are diffuse, irregular loss of axons and myelin accompanied by widespread gliosis, tissue death due to an infarction or loss of blood supply to the brain, and changes in the plasticity of the arteries. The pathologic mechanism may be damage caused by severe atherosclerosis. The onset of this disease is typically between ...
Atherosclerosis happens when a fatty substance called plaque builds up inside your arteries. There are typically few noticeable symptoms until the situation becomes dire and you experience ...
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.

Ischemic stroke is a thrombotic, or rarely, thromboembolic or atherosclerotic complication of arteries supplying the brain. [9] Occlusion of brain arteries leads to rapid ischemic death of neurons, both at the infarct core and ischemic penumbra. [10] [37] Similar to cardiomyocytes, neurons require constant perfusion for proper function.
