Alzheimer’s is a cause of concern for doctors. Moreover detecting signs of the disease has been at the centre of scientific research for a long time. Doctors strongly believe that earlier detection could help in treatment of the disease.

Many researchers too have been done on the subject. A new study has pointed out that use of radiation could be helpful in detecting the disease.

And in this direction MRIs (magnetic resonance imaging) could be extremely useful as it could detect biomarkers of dementia in older adults before symptoms develop.

microscope accuracy 20 times betterStudy author Sven Haller, M.D., from the University of Geneva in Geneva, Switzerland, reported in the press release: “ASL MRI is simple to perform, doesn’t require special equipment and only adds a few minutes to the exam.”

Researchers concluded their study findings after recruiting two groups of older adults: Of them 148 adults had no neuropsychiatric illness and 65 with mild cognitive impairment. Once the selection process was over the participants went for the arterial spin labelling.

And it was during this process that every participant was observed and studied minutely. Dr. Haller said: “There is a known close link between neural activity and brain perfusion in the posterior cingulate cortex. Less perfusion indicates decreased neural activity.”
