Is this why our kids may be heading for early Alzheimers?

A large, multi-center study led by the UC Davis School of Medicine for the first time has shown that people as young as their 40s have stiffening of the arteries that is associated with subtle structural damage to the brain that is implicated in cognitive decline and Alzheimer’s disease later in life.

A collaboration of UC Davis, the Framingham Heart Study and Boston University, among others, the study found that, among young healthy adults, higher aortic “stiffness” was associated with reduced white matter volume and decreased integrity of the gray matter, and in ages much younger than previously described.

Effects of Arterial Stiffness on Brain Integrity in Young Adults from the Framingham Heart Study,” is published online in the American Heart Association journal Stroke.

“This study shows for the first time that increasing arterial stiffness is detrimental to the brain, and that increasing stiffness and brain injury begin in early middle life, before we commonly think of prevalent diseases such as atherosclerosis, coronary artery disease or stroke having an impact,” said Pauline Maillard, UC Davis Department of Neurology and Center for Neuroscience and the study’s lead author.

“These results may be a new avenue of treatment to sustain brain health,” she said.

The study also noted that elevated arterial stiffness is the earliest manifestation of systolic hypertension.

“Measures of arterial stiffness may actually be a better measure of vascular health, and should be identified, treated and monitored throughout the lifespan,” Maillard said.

The large study involved approximately 1,900 diverse participants in the Framingham Heart Study, who underwent brain magnetic resonance imaging (MRI), as well as arterial tonometry.

The tests measured the force of arterial blood flow, the carotid femoral pulse wave velocity or CFPWV — the reference standard for noninvasive measurement of aortic stiffness — and its association with subtle injury to the brain’s white and gray matter. The research found that increased CFPWV was associated with greater injury to the brain.

The reasons this is so are complex, and more study is needed, Maillard said. However, with age high blood pressure causes the arteries to stiffen, further increasing blood pressure as well as increasing calcium and collagen deposits, which promotes atrophy, inflammation and further stiffening, decreasing blood flow to vital organs including the brain and promoting brain atrophy.

“Our results emphasize the need for primary and secondary prevention of vascular stiffness and remodeling as a way to protect brain health,” early in life, Maillard said.


Ian: A truly frightening possibility that the scientists admit to having no immediate answer. me? I’m taking Vitamin K2 to ensure my calcium goes where it should rather than¬†accreting on my blood vessels. And I’m taking molecular hydrogen every day because I’ve experienced the clarity of mind. H2 crosses the body/brain barrier with ease in its quest for free radicals and inflammation.
