CAA is a cerebrovascular disease caused by the deposition of β-amyloid in the walls of arteries, arterioles, and capillaries in the cerebral cortex and overlying leptomeninges. It is often associated with repeated lobar intracerebral hemorrhages, progressive cognitive decline, transient neurological symptoms and gait disturbances. No treatment is specific for symptomatic management of CAA up to date. Remote ischemic conditioning is a non-invasive strategy to protect the brain. The clinical trials have demonstrated that daily limb RIC seems to be potentially effective in patients with cerebral small-vessel disease in slowing cognition decline and reducing white matter hyperintensities. Thereby, investigators design this study to assess whether RIC has a beneficial effect on CAA.
Cerebral amyloid angiopathy (CAA) is a common form of cerebral small vessel disease, characterized by symptomatic intracerebral hemorrhage and cognitive impairment. However, no effective prevention and treatment strategies have been established. This study aims to evaluate the safety and efficacy of remote ischemic conditioning on patients with CAA.
