Anti-amyloid immunotherapies have recently emerged as treatments for Alzheimer's disease. While these therapies have demonstrated efficacy in clearing amyloid-β and slowing cognitive decline, they have also been associated with amyloid-related imaging abnormalities (ARIA) which include both edema (ARIA-E) and hemorrhage (ARIA-H). Given that ARIA have been associated with significant morbidity in cases of antithrombotic or thrombolytic therapy, an understanding of mechanisms of and risk factors for ARIA is of critical importance for stroke care. We discuss the latest data regarding mechanisms of ARIA, including the role of underlying cerebral amyloid angiopathy, and implications for ischemic stroke prevention and management.

The isoform E4 of the Apolipoprotein E (ApoE) represents one of the strongest genetic risk factors for late-onset Alzheimer's disease (AD). ApoE has key roles in cholesterol transport and amyloid-β (Aβ) metabolism, which are both central to AD pathogenesis. The E4 isoform has been implicated in reduced cholesterol homeostasis, increased Aβ aggregation, and heightened tau phosphorylation, contributing to amyloid plaques and neurodegeneration.
