An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall. [1] [2]The material consists of mostly macrophage cells, [3] [4] or debris, containing lipids, calcium and a variable amount of fibrous connective tissue.
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 ...
There was some atheroma in the internal brain arteries that led to the cerebral softening of the left side of the brain around the left lateral ventricle, thalamus and corpus striatum. There were similar right sided numbness in some patients, coldness of the extremities, and impairments in vision.
“Estrogen, particularly estradiol, the strongest form, plays a critical role in the brain’s health and functionality, earning it the title of the ‘master regulator’ of women’s brain health.
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.
As long as the artery enlarges sufficiently to compensate for the extra thickness of the atheroma, then no narrowing ("stenosis") of the opening ("lumen") occurs. The artery expands with an egg-shaped cross-section, still with a circular opening. If the enlargement is beyond proportion to the atheroma thickness, then an aneurysm is created. [71]
The brain may contain higher -- and more significant -- amounts of microplastics than other organs in the body, according to a new study. ... "They're not saying that in any way, shape or form. It ...
Foam cells form the fatty streaks of the plaques of atheroma in the tunica intima of arteries. Foam cells are not dangerous as such, but can become a problem when they accumulate at particular foci thus creating a necrotic centre of atherosclerosis.
