Stroke occurs when blood vessels bringing oxygen to the brain burst or become clogged. The discovery eventually may lead to practical therapies for stroke and Alzheimer's disease.
Stroke occurs when blood vessels bringing oxygen to the brain burst or become clogged.
As a result, the brain does not receive essential blood flow, and a portion will die. Oxidative stress is a common factor in AD and stroke, as well as in a variety of other illnesses. It occurs when free radicals, highly reactive molecules, accumulate and cause damage to other molecules within the body. They bind to proteins, accumulate in lipids, and damage nucleic acids. Antioxidants help control oxidative stress by scavenging free radicals.
