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.

15% strokes occur during sleep making treatment difficult: Study

According to a new study nearly 15 percent of people who have a stroke are not eligible for clot-busting treatment because the stroke happened while they slept. These clot breaking drugs can prevent permanent disability after a stroke - but the treatment must be given within a four-and-a-half-hour window after the stroke symptoms begin say experts. Since people who have a stroke while asleep can't know when it occurred, they can't get the treatment if they slept for more than four and a half hours, explained study author Dr. Jason Mackey at the University of Cincinnati. “They can't get the drug,” he said. “That's a big issue.”
