Scientists have developed a new, highly accurate test to predict whether a person will develop dementia.The method, created by researchers from Queen Mary University of London, can be used up to nine years before a diagnosis and can predict dementia with more than 80% accuracy.To create the predictive test, the team used functional MRI scanning—a non-invasive brain imaging technique—to detect changes in the brain's 'default mode network,' or DMN.
They found that this method accurately predicted the onset of dementia up to nine years before an official diagnosis was made. The test was also able to predict how long it would take a diagnosis to be made within a two-year margin of error, in the cases where the study participants did develop dementia.Additionally, the researchers found that the genetic risk for Alzheimer's disease was strongly linked with connectivity changes in the DMN.
