Cerebrovascular Management Considerations in Patients on AATs.

The prevalence of Alzheimer's Disease (AD) is increasing worldwide, with more emergency providers and neurologists expecting to encounter these patients. The paradigm of management of AD is expected to change given the recent approval of anti-amyloid therapies (AATs). The most concerning complication of these therapies is amyloid-related imaging abnormalities (ARIA), which can lead to an increased risk of cerebrovascular complications. Given a growing population of patients with AD and growing use of AATs, providers must be prepared to manage patients at risk of cerebrovascular disease and those presenting with neurologic deficits. This subpopulation warrants a unique approach given the risk of ischemic stroke and the associated risk of hemorrhage present in the use of AATs. In this narrative review, we present and propose management considerations in the acute stroke setting and patients at risk of cerebrovascular disease, including patients with indications for anticoagulation, to most appropriately manage this special population. Future cross-disciplinary collaboration and use of registry data will be essential to narrow management approaches and develop safety data.
