Introduction: Alzheimer's disease is a neurodegenerative disease that initially manifests itself primarily as impaired short-term memory and impaired language ability. The course of the disease is mainly due to an atrophy in the brain that can be attributed to the protein amyloid B and tau. Monoclonal antibodies that target Alzheimer's disease often have a high rate of cerebral edema, where proteinaceous fluid leaks into the extracellular space of the brain and creates edema. Some of the most common symptoms for amyloid-related imaging abnormalities (ARIA-E) are headache, dizziness, and blurred vision. In a few cases, patients with ARIA-E need to be hospitalized for observation, but most show a decline in ARIA-E within one to two months. Objective: To investigate the frequency of ARIA-E in clinical studies of monoclonal antibodies to patients with Alzhiemer's disease and to investigate the role of the ApoE4 allele in the development of ARIA-E. Method: Literature review of five RCT studies based on four different monoclonal antibodies. PubMed was used to search for the RCT-studies. Results: ARIA-E varies between different types of antibodies. ARIA-E usually occurs early in treatment when the degree of amyloid b is highest in the brain. Most cases are asymptomatic and treatment resumes within 1-2 months. Conclusion: Aria-E frequency correlates strongly with dose strength as well as APOE4 -status and most of the incidences are asymptomatic. With the right titration and individually selected drugs as well as individual dosages a safe care can be established for patients with Alzheimer's disease. If treatment is initiated at an early stage, the risk of side effects is reduced and more neurons can be saved from atrophy. The combination of several different types of medicine will further reduce the risk of ARIA-E.
