Vascular brain injury from conditions such as hypertension and stroke can have “distinctly negative effects”
Vascular brain injury from conditions such as hypertension and stroke can have “distinctly negative effects” on the ability to solve problem and organize thoughts as we age, experts say.
Bruce Reed, professor of neurology at the University of California, Davis, and colleagues wanted to see if there was a correlation between vascular brain injury from hypertension and stroke and the deposition of beta amyloid plaques, thought to be an early and important marker of Alzheimer’s disease. They also wanted to decipher what effect each has on memory and executive functioning
“The first question was whether those two pathologies correlate to each other, and the simple answer is ‘no.’ Earlier research, conducted in animals, has suggested that having a stroke causes more beta amyloid deposition in the brain,” Reed said. “If that were the case, people who had more vascular brain injury should have higher levels of beta amyloid.
