• Resumen

  • A major breakthrough in tracing the course of Alzheimer's disease comes as the US government announces its largest grant so far to test drugs on people at greatest risk of the condition. For the first time, both brain abnormalities that underlie Alzheimer's can be viewed simultaneously in brain scans. The technique will help doctors track the disease and figure out whether drugs are working. Beta amyloid plaques and tau tangles are the two main abnormalities in the brains of people with Alzheimer's. Tracer chemicals that highlight beta amyloid plaques were developed in 2005--a tracer for tau tangles completes the picture.
