Scientists at the Medical University of South Carolina (MUSC) have uncovered mechanisms by which high levels of a hormone called FGF23 can reduce brain health.
In results published in the journal PLoS ONE, high levels of fibroblast growth factor 23 (FGF23) were associated with structural changes in the brain’s frontal lobes. High FGF23 levels are thought to lead to the vascular calcification seen in patients with chronic kidney disease. The study showed that such a process may also affect the brain in patients without chronic kidney disease but with elevated cardiovascular risk factors, according to Leonardo Bonilha, M.D., Ph.D., associate professor of neurology in the MUSC Department of Medicine and director of the study.
“We found that there is a relationship between high levels of FGF23 and a form of structural compromise in the brain,” said Bonilha.
FGF23 is produced in the bone. Normally, FGF23 works in the kidneys and the gut to regulate levels of calcium and phosphate in the body. It is thought to be increased in people who eat a diet high in phosphates, which are often found in foods with preservatives. In people with chronic kidney disease or in those who consume a diet high in phosphates, can be a calcification of their arteries, which can cause heart attack or stroke. FGF23 may be the reason.
