It may imitate, and is in turn imitated by, a number of other diseases that affect the blood vessels of the brain diffusely such as fibromuscular dysplasia and thrombotic thrombocytopenic purpura. [3] Primary CNS vasculitis has an incidence of 2.4 cases per 1 million people, with an associated mortality of 8-23% and a 25% risk of severe ...
Brain atrophy from vascular dementia: Specialty: Psychiatry, neurology Symptoms: Cognitive impairment, short-term memory loss [3] Complications: Heart disease, loss of ability to care for self and interact, pneumonia [4] Causes: Conditions that impair blood vessels in the brain and therefore interfere with oxygen delivery to the brain [3] Risk ...
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.
Arterioles can become permeable resulting in compromise of the blood–brain barrier. [4] [10] It has been shown that Binswanger's disease targets the vessels in this zone of the subcortex, but spares the microcirculation's vessels and capillaries which may be attributed to a difference between Alzheimer's and Binswanger's disease.

This disease is associated witih DNA damage (chromosome damage) caused by a toxic mutant TREX1 protein, which causes organ damage mimicking radiation injury. [2] [3] RVCL affects small blood vessels, which disrupts blood flow to multiple organs including but not limited to the retina and the white matter of the central nervous system.
Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis. [5] Atherosclerosis narrows blood vessels in the brain, resulting in decreased cerebral perfusion.
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 ...
Common underlying causes are severely elevated blood pressure, kidney failure, severe infections, certain medications, some autoimmune diseases, and pre-eclampsia. The diagnosis is usually made by a brain scan , in which areas of swelling can be identified.
