Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

AI-powered digital twin of mouse visual cortex

Much as a pilot might practice maneuvers in a flight simulator, scientists might soon be able to perform experiments on a realistic simulation of the mouse brain. In a new study, Stanford Medicine researchers and collaborators used an artificial intelligence model to build a "digital twin" of the part of the mouse brain that processes visual information.

Study explores impact of parental Alzheimer’s on tau protein spread in the brain

While some studies have suggested that having a mother with Alzheimer's disease may put you more at risk of developing the disease, a new study finds that having a father with the disease may be tied to a greater spread of the tau protein in the brain that is a sign of the disease, according to a study published on April 9, 2025, online in Neurology®, the medical journal of the American Academy of Neurology.
