Early Alzheimer's could be discovered by MRI
Contemporary Long-Term Care Weekly, August 27, 2009
The Cleveland Clinic recently released a study that suggests hyperactivity occurs in the brain during the earliest phases of Alzheimer’s disease, according to U.S. News & World Report. This hyperactivity likely takes place so that the brain can compensate for deterioration related to the disease. Using a Magnetic Resonance Imaging (MRI) scan to detect such activity in the early stages allows for improved treatment and the potential to delay the onset of Alzheimer’s, according to the study.
Researchers used a functional MRI to monitor the brain activity of 69 study participants, all of whom were mentally healthy adults, with two-thirds cited as being at-risk for Alzheimer’s disease due to genetic markers or family history. The participants were asked to recognize the names of unfamiliar people and celebrities. Researchers found increased activity in certain portions of the brain for at-risk individuals after comparing the MRI scans of the two groups.
