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 ...
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.
In small vessel disease, the frontal lobes are often affected. Consequently, people with vascular dementia tend to perform worse than their Alzheimer's disease counterparts in frontal lobe tasks, such as verbal fluency, and may present with frontal lobe problems: apathy , abulia (lack of will or initiative), problems with attention, orientation ...
Since blockage of the artery is gradual, the onset of symptomatic thrombotic strokes is slower. Thrombotic stroke can be divided into two categories — large vessel disease or small vessel disease. The former affects vessels such as the internal carotids, vertebral and the circle of Willis. The latter can affect smaller vessels, such as the ...
Binswanger's disease, also known as subcortical leukoencephalopathy and subcortical arteriosclerotic encephalopathy, [1] is a form of small-vessel vascular dementia caused by damage to the white brain matter. [2] White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age. [3]
Cerebral vasculitis (sometimes the word angiitis is used instead of "vasculitis") is vasculitis (inflammation of the blood vessel wall) involving the brain and occasionally the spinal cord. [1] It affects all of the vessels: very small blood vessels ( capillaries ), medium-size blood vessels ( arterioles and venules ), or large blood vessels ...
It is an autoimmune disease and a form of vasculitis that affects small- and medium-size vessels in many organs but most commonly affects the upper respiratory tract, lungs and kidneys. [6] The signs and symptoms of GPA are highly varied and reflect which organs are supplied by the affected blood vessels.
Endothelium lines the inner wall of the vessel. Vascular disease is a pathological state of large and medium muscular arteries and is triggered by endothelial cell dysfunction. [22] Because of factors like pathogens, oxidized LDL particles and other inflammatory stimuli endothelial cells become active. [23]
