Since then, LA and other cerebrovascular diseases have become the research focus of scholars at home and abroad. However, the molecular, cellular and pathogenesis of cerebrovascular disease are still unclear. Cerebral small vessel disease is caused by the lesions of perforating arteries, capillaries and veins of the brain. Modern imaging technology makes it possible to classify these diseases that can not be directly distinguished in clinical practice. The imaging features of cerebral infarction include cerebral microvascular atrophy. At present, a large number of studies have been carried out around LA, such as the pathogenesis, risk factors, imaging manifestations and classification, pathophysiological changes, hemodynamics, gene polymorphism and so on. In addition, although LA belongs to the category of cerebral small vessel disease, more scholars believe that there are countless links between large artery atherosclerosis and LA, and to some extent, have the same pathogenesis.
