Researchers devote a lot of time to finding ways of diagnosing Alzheimer's disease early; something that allows for prompt treatment to slow down the effects of the disease. Researchers from the University of Gothenburg have been looking at the levels of three proteins, associated with Alzheimer's disease, in the cerebrospinal fluid. They studied 750 people with mild cognitive impairment, 529 with Alzheimer's and 304 healthy people. The people with cognitive impairment were monitored for two years to see whether they went on to develop Alzheimer's. The scientists found that the three proteins (or levels thereof) accurately identified 62% of those who would go on to develop Alzheimer's and were 88% accurate at ruling it out; an accuracy level insufficient for use as a diagnostic tool.
