The term cerebral small vessel disease refers to a group of pathological processes with
various aetiologies that affect the small arteries, arterioles, venules, and capillaries of the
brain. Age-related and hypertension-related small vessel diseases and cerebral amyloid
angiopathy are the most common forms. The consequences of small vessel disease on the
brain parenchyma are mainly lesions located in the subcortical structures such as lacunar
infarcts, white matter lesions, large haemorrhages, and microbleeds. Because lacunar …
Summary
The term cerebral small vessel disease refers to a group of pathological processes with various aetiologies that affect the small arteries, arterioles, venules, and capillaries of the brain. Age-related and hypertension-related small vessel diseases and cerebral amyloid angiopathy are the most common forms. The consequences of small vessel disease on the brain parenchyma are mainly lesions located in the subcortical structures such as lacunar infarcts, white matter lesions, large haemorrhages, and microbleeds. Because lacunar infarcts and white matter lesions are easily detected by neuroimaging, whereas small vessels are not, the term small vessel disease is frequently used to describe the parenchyma lesions rather than the underlying small vessel alterations. This classification, however, restricts the definition of small vessel disease to ischaemic lesions and might be misleading. Small vessel disease has an important role in cerebrovascular disease and is a leading cause of cognitive decline and functional loss in the elderly. Small vessel disease should be a main target for preventive and treatment strategies, but all types of presentation and complications should be taken into account.
