A method for detecting early signs of Alzheimer's disease using amyloid PET imaging works as well as the previously used cerebrospinal fluid sample method.

For several years it has also been possible to carry out an analysis of a cerebrospinal fluid sample which increases the chances of early detection. So far, however, only patients in memory clinics have been offered the test. Recently, a method known as amyloid PET was approved for clinical use in Sweden. A special substance which binds to a protein in the brain, ?-amyloid, is administered to the patient.
