BACKGROUND: Tau neurofibrillary tangles and senile plaques comprised of insoluble amyloid beta are the major histopathological hallmarks of Alzheimer's disease (AD). More than 85% of autopsy-confirmed AD cases also exhibit some degree of cerebral amyloid angiopathy (CAA), which is characterized by amyloid beta peptide deposits predominantly in blood vessels in the meningeal and intracerebral blood vessels. Consequently, CAA predisposes individuals with AD to cerebral infarction and hemorrhages, accounting for ∼20% of cases in the elderly, which could lead to faster cognitive decline through neurovascular pathway dysfunction...
