New biomarkers for Alzheimer’s disease are a priority area for researchers seeking to learn more about the disease and find possible methods of early diagnosis. Researchers at Karolinska Institutet in Sweden have now studied a new PET tracer that is an important diagnostic tool for the disease. The study on the tracer substance BU99008, which is published in Molecular Psychiatry, can play a key part in the early identification of signs of Alzheimer’s disease.
