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 ...
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
Calcification forms among vascular smooth muscle cells of the surrounding muscular layer, specifically in the muscle cells adjacent to atheromas and on the surface of atheroma plaques and tissue. [69] In time, as cells die, this leads to extracellular calcium deposits between the muscular wall and outer portion of the atheromatous plaques.
Monckeberg's calcification typically occurs near the internal elastic lamina or, less frequently, in the media of muscular arteries without alterations in calcium metabolism. Its clinical importance is not yet fully understood. Some recent studies suggest a connection between Monckeberg's calcification and metabolic vascular calcification.
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 ...
Dr. Rohit Vuppuluri, DO, FACC, RPVI, a vascular cardiologist in Chicago, Illinois, says that one way to know how much coronary calcification you have is by getting a coronary calcium scan. “A ...
Calcification seems to be progressive, since calcifications are generally more extensive in older individuals and an increase in calcification can sometimes be documented on follow up of affected subjects. [citation needed] As well as the usual sites the cerebellar gyri, brain stem, centrum semiovale and subcortical white matter may also be ...
Brain healing is the process that occurs after the brain has been damaged. If an individual survives brain damage, the brain has a remarkable ability to adapt. When cells in the brain are damaged and die, for instance by stroke, there will be no repair or scar formation for those cells.
