Dementia Can Now Be Predicted Will Almost 89 Percent Accuracy Using MRI Scanning

A recent study held in Los Angeles by the researchers from University of Washington and University of California have proved that dementia can be predicted and thus prevented with almost 89 percent accuracy with the help of MRI scanning. The scientist used MRI scanning and scanned brains of the patients and during the study and came across the results, and stated that the doctors will now be able detect dementia even before the patient experiences any symptoms. A professor at the University of Washington, Cyrus A Raji explained that at present it is still difficult to predict dementia in people among elder age group, while in the younger age group dementia can be detected before even any medical sign shows up with a single MRI scan. The researchers also made a point that they realize that there no drugs available in the market that can delay or prevent Alzheimer’s that may have somehow helped people under the threat. The doctors used the technique known as diffusion tensor imaging to evaluate the white matter of the brain; the white matter of the brain enables communication between different parts of the brain. The research proved that if the water molecules are moving abnormally that may harm the white matter and later create problems with cognition. The doctors made use of the information from the Alzheimer's disease Neuroimaging Initiative which is a collaboration that conducts test and studies regarding Alzheimer’s, the doctors studied information of 10 people who started suffering from the disease and compared it with information of 10 people who had a steady mind and brain, each group consisted of people with an average age of 73, and realized that the people suffering had more damage to the white matter of the brain, the test was repeated on another group of 61 people to understand the white matter in a more refined way. The doctors after every test were able to predict dementia by almost 89 percent and when they looked more into the damaged part of the brain the percentage rose to almost 95 percent.
