Alzheimer's transmission via transfusions
Recent studies suggest that Alzheimer's disease may be transmitted through blood transfusions, due to the presence of beta-amyloid proteins in donors' blood. A large-scale study conducted in Denmark and Sweden found that individuals who received blood from donors with amyloid-related disorders were more likely to experience recurrent brain hemorrhages, a condition linked to cerebral amyloid angiopathy, which is also associated with Alzheimer's. Researchers believe that these proteins can be transferred via blood, highlighting the need for extensive preventive testing and donor screening to reduce potential risks. Experts emphasize the importance of further research to determine the extent of protein transmission through blood and whether strict protective measures are necessary—especially in light of past scandals involving contaminated blood in Britain.
