Alzheimer's breakthrough: Scan could predict those at risk
AUSTRALIAN scientists have discovered scans for iron levels in the brain could identify people most at risk of Alzheimer's.
In a major breakthrough in the fight against the devastating disease, scientists have found that those with significant brain plaque but low iron levels maintain cognitive performance over as much as six years.
But those with high iron levels - particularly in the hippocampus, the part of the brain involved in memory formation - progress faster to disease.
A team from the Florey Institute of Neuroscience and Mental Health and the CSIRO are behind the finding.
