Pathophysiologic mechanisms in cerebral amyloid angiopathy / 国际脑血管病杂志

ABSTRACT

Cerebral amyloid angiopathy (CAA) is characterized by leptomeningeal and β-amyloid deposition in arteriole wall in cortex, and it is one of the common cerebral vascular diseases in the elderly. It is correlated with Alzheimer's disease, intracerebral hemorrhage, cerebral infarction and leukoencephalopathy. CAA is divided into hereditary and sporadic types, and the latter is most common. This article reviews the advances in research on the pathophysiological mechanisms of sporadic CAA, particularly the production of β-amyloid protein and clearance mechanism in brain tissue.
