As the third-leading cause of deaths in the United States, strokes were the focus of several presentations during Palm Oil Nutrition Week. Revascularization, the process in which blood vessels regain the ability to transport blood, was central to a study conducted by Dr. Cameron Rink. Interested to learn new scientific advances in how the brain recovers from stroke damage, Drs. Shawn Talbott and Sherry Torkos attended his lecture called, “Palm Tocotrienol Attenuates Stroke Injury and Improves Collateral Circulation During Cerebral Ischemia.”
Dr. Rink’s research focused on how blood vessels in the brain respond to ischemic stroke. “Accounting for about 85 percent of strokes, ischemic strokes are the most common,” explained Torkos. Occurring when an artery is blocked, ischemic strokes quickly deprive the brain of oxygen.
Using animal models, Dr. Rink divided the subjects into a placebo group and a group that received prophylactic supplementation of tocotrienols. After 10 weeks, he induced strokes and looked at the post-stroke effects. “Brains of those supplemented with tocotrienols showed significant anteriogenesis,” said Talbott.
“Anteriogenesis is the remodeling of existing collateral blood vessels in the brain,” Talbott clarified. “It’s different from angiogensis, which is the creation of new blood vessels.” The placebo group did not show any signs of remodeling and had more trouble moving around.
Excited by results that no drugs can currently duplicate, Torkos added, “Dr. Rink’s research is ongoing and funded by the American Heart Association to investigate how tocotrienols can protect collateral blood vessels after stroke.”
Dr. Rink works at Ohio State University and has spoken before about the health benefits of tocotrienols. He also co-authored a study that researched the neurological impact of tocotrienols. It was supported by the US National Institutes of Health.
