Microangiopathy (also known as microvascular disease, small vessel disease (SVD) or microvascular dysfunction) is a disease of the microvessels, small blood vessels in the microcirculation. [1] It can be contrasted to macroangiopathies such as atherosclerosis , where large and medium-sized arteries (e.g., aorta , carotid and coronary arteries ...
CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...
There are two types of angiopathy: macroangiopathy and microangiopathy. [2] In macroangiopathy, atherosclerosis and a resultant blood clot forms on the large blood vessels, sticks to the vessel walls, and blocks the flow of blood. Macroangiopathy in the heart is coronary artery disease; in the brain, it is cerebrovascular disease.
Cerebroretinal microangiopathy with calcifications and cysts (CRMCC) is a rare genetic disorder, which affects multiple organs. [1] [2] Its hallmarks are widespread progressive calcifications, cysts and abnormalities of the white matter of the brain, usually occurring together with abnormalities of the blood vessels of the retina.
Although not many studies have been conducted and little is known about microinfarcts and other vascular or epidemiological risk factors, [5] these brain lesions are thought to be masked by other pathologies. [7] However, the common macroscopic infarct is not exhibited in 45% of people tested for microinfarcts. [8]
There’s one more unexpected but essential key to brain protection: a sense of purpose. “A very robust predictor of health outcomes is the sense that your life is meaningful,” Boyle says.
Congenital diseases are medical conditions that are present at birth that may be associated with or inherited through genes. [16] Examples of congenital cerebrovascular diseases include arteriovenous malformations, germinal matrix hemorrhage, and CADASIL (cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy).

The skull bone behind Hermansen’s right eye was gone. In its place was a hole, allowing her brain to press against the eye, which explained the pulsating, said Dr. Netanel Ben-Shalom, a ...
