Scans shows aging brains can leak
Recently, MRI (magnetic resonance imaging) scans show that the blood-brain barrier weakens as a person gets older. People 55 to 85 years old with some memory problems such as dementia and Alzheimer’s, tend to have leaks in the blood-brain barrier. Neuroscientist Berislav Zlovokic’s team reported its new findings on January 21 in the journal Neuron. The team used gadolinium, a tracking element, to see precisely where the blood flows in the brain’s of people aged from 23 to 91 years old. We still do not know which comes first the Alzheimer’s or the leakage of chemicals. The next step is for researchers to figure out which is the cause and which is the effect.
