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.

The Moslows' $4 million gift transforms women's health education and research

When Linda Moslow, A16P, A18P, entered perimenopause in her early 40s, she was blindsided. "I'd always been healthy and grounded in wellness," she says. "Suddenly, I couldn't recognize myself." The months of anxiety, sleeplessness, and confusion that followed left her feeling unmoored until she found a team of doctors who helped her understand what was happening.
