Lipohyalinosis is a cerebral small vessel disease affecting the small arteries, arterioles or capillaries in the brain.Originally defined by C. Miller Fisher as 'segmental arteriolar wall disorganisation', it is characterized by vessel wall thickening and a resultant reduction in luminal diameter.
This type of stroke often causes lesions in the surrounding brain tissue that are visibly detected via neuroimaging techniques such as MRI and computed axial tomography (CT scan). Silent strokes, including silent lacunar infarctions, have been shown to be much more common than previously thought, with an estimated prevalence rate of eleven ...
However, the mutation causes accumulation of this protein within small to medium-sized blood vessels. [19] This disease often presents in early adulthood with migraines, stroke, mood disturbances, and cognitive deterioration. MRI shows white matter changes in the brain and also signs of repeated strokes. The diagnosis can be confirmed by gene ...

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 ...
A microinfarct is a microscopic stroke generally ranging between 0.1 millimeter and 1 millimeter in size. [1] [2] Microinfarcts can be found in 25-50% of all elderly deceased persons. Microinfarcts may be the second most important cause of dementia, after Alzheimer's disease. [3] [4]
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
It affects all of the vessels: very small blood vessels (capillaries), medium-size blood vessels (arterioles and venules), or large blood vessels (arteries and veins). If blood flow in a vessel with vasculitis is reduced or stopped, the parts of the body that receive blood from that vessel begins to die, resulting in a stroke .
