Abstract

Intracranial hemorrhage (ICH) is the major complication of oral anticoagulant therapy. Cerebral amyloid angiopathy (CAA) is an age-related disease characterized by the pathological deposition of beta-amyloid protein in leptomeningeal and cortical cerebral vessels. Such vascular alterations expose to the risk of spontaneous vascular rupture. The main clinical manifestations are represented by ICH, cognitive decline and transient focal neurological episodes (TFNE). In the patient subgroup with TFNE, a misdiagnosis with transient ischemic attack may have catastrophic consequences, resulting in a significant increase in the risk of spontaneous ICH within weeks after clinical onset, with potentially devastating consequences if anticoagulant therapy is started.The prevention of bleeding complications related to CAA is based on disease knowledge. This is particularly relevant because non-pharmacological treatment options, including percutaneous left atrial appendage occlusion, are emerging as an alternative to traditional anticoagulant therapies in patients at high bleeding risk.
