The first new guidelines for diagnosing Alzheimer's disease in nearly 30 years establish earlier stages of the mind-robbing disease, paving the way for spotting and possibly treating these conditions much sooner than they are now.
The change reflects a modern view that Alzheimer's is a spectrum of mental decline, with damage that can start many years before symptoms appear.
The new guidance describes three phases: early brain changes, mild cognitive impairment and full-blown Alzheimer's.
Yet the guidelines do not advise doctors to change how they evaluate and treat patients now. Despite the hoopla about new brain scans and blood and spinal fluid tests that claim to show early signs of Alzheimer's, they are not ready for prime time and should remain just tools for research, the guidelines say.
