    Cerebral amyloid angiopathy (CAA) Vascular amyloid beta protein (Aβ) Intracerebral hemorrhage (ICH) Cerebral microbleeds (CMBS) Cortical superficial siderosis (CSS)


    In CAA patients, a greater burden of hemorrhagic (ICH, CMBS, and CSS) and ischemic (white matter lesions and microinfarcts) consequences was associated with cognitive impairment


    Here, we evaluated whole-brain CVR in CAA patients under high carbon dioxide gas stimulation, compared CVR among CAA patients, mild cognitive impairment and AD patients, and healthy controls, and explored MRI markers of CVR and CAA.



    Study Design Hypertension

    • There were 26 patients with cerebral amyloid angiopathy (9 females, age 74.
