Brain scans may help predict which adults with mild cognitive impairment are likelier to develop Alzheimer`s disease, according to a new study.
The researchers used the MRI to measure the thickness of the cerebral cortex - key to memory, attention, thought and language and observed the pattern of thinning to compute a risk score. Using the baseline MRI, they calculated that the patients with MCI had a one-year risk of conversion to AD ranging from three to 40 per cent. By combining results of the baseline MRI and the MRI exam performed one year later, the researchers were able to calculate a rate of change in brain atrophy that was even more informative. The MCI patients` risk of disease progression based on the serial MR exams ranged from 3 to 69 per cent. The results appear online and will be published in the June issue of Radiology . ANI
