New treatments and simple blood tests could change how doctors detect and treat Alzheimer's disease, according to a new report from the Alzheimer's Association.
Blood tests to detect Alzheimer's are not yet approved for everyday use, but in research studies, they have improved the accuracy of diagnosis by up to 91 percent. Right now, doctors rely on PET brain scans to find amyloid plaques or do a spinal tap to check for abnormal levels of proteins like beta-amyloid and tau.
These tests are expensive, invasive and not always easy to access. Blood tests could make it much simpler to find early signs of the disease and be more widely available.
