You know that dizzy feeling you get when, after lying down for an extended period, you stand up a little too quickly?
That feeling is caused by a sudden reduction of blood flow to the brain, a reduction of around 30 percent. Now imagine living every minute of every day with that level of decreased blood flow.
People with Alzheimer’s disease don’t have to imagine it. The existence of cerebral blood flow reduction in Alzheimer’s patients has been known for decades, but the exact correlation to impaired cognitive function is less understood.
“People probably adapt to the decreased blood flow, so that they don’t feel dizzy all of the time, but there’s clear evidence that it impacts cognitive function,” said Chris Schaffer, associate professor in the Meinig School of Biomedical Engineering.
