Water in the Brain Hints at Early Cognitive Decline IRVINE, Calif., Sept. 26 -- Early signs of Alzheimer's disease may show up in subtle changes in the diffusion of water in key brain structures, as revealed by MRI, researchers here suggested.
In a small study, patients with mild cognitive impairment were found to have elevations in apparent diffusion coefficient in brain areas governing memory when compared with control patients, and reported Min-Ying Su, Ph.D., of the University of California at Irvine, and colleagues, in the October issue of Radiology. These elevations correlated with worse memory performance scores, the investigators added. "Our methods may enable earlier diagnosis of Alzheimer's disease, allowing earlier intervention to slow down disease......... progression," they said. |
