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). [9]
Stroke is a medical condition in which poor blood flow to a part of the brain causes cell death. [5] There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. [5]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
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 ...
Vascular dementia can sometimes be triggered by cerebral amyloid angiopathy, which involves accumulation of amyloid beta plaques in the walls of the cerebral arteries, leading to breakdown and rupture of the vessels. [2] [5] Since amyloid plaques are a characteristic feature of Alzheimer's disease, vascular dementia may occur as a consequence ...
[14] [30] MS is also more common in women, while venous diseases are more common in men. Venous pathology is commonly associated with hypertension, infarcts, edema and transient ischemia, and occurs more often with age, however these conditions are hardly ever seen in MS and the disease seldom appears after age 50. Finally, an organ-specific ...
A cerebral AVM is an abnormal anastomosis (connection) between the arteries and veins in the brain due to the lack of a capillary bed, and are most commonly of prenatal origin. [ 10 ] [ 11 ] In normal cerebral circulation , oxygen-enriched blood from the heart travels in sequence through smaller blood vessels going from arteries, to arterioles ...
Macrovascular disease is a disease of any large (macro) blood vessels in the body. It is a disease of the large blood vessels, including the coronary arteries, the aorta, and the sizable arteries in the brain and in the limbs. This sometimes occurs when a person has had diabetes for an extended period of time.
