Unclogging blood flow to the brain could open the floodgates for Alzheimer’s treatment

Cognitive impairment and a build-up of abnormal proteins in the brain are better known tell-tale signs of Alzheimer’s disease, but other clues may reveal its presence earlier in the piece. Among those is a reduced blood flow to the brain, and scientists from Cornell University believe they have now found an explanation for these blockages, raising new hopes for treatments that target one of the disease’s potential root causes.
