Everything about a stroke demands speed. The symptoms of stroke are abrupt, the diagnosis must be prompt, and the treatment must be immediate. For every minute a stroke is untreated, a person can lose around 1.9 million neurons, according to the National Stroke Association.
“We know ‘time is brain,’” says Carolyn Brockington, MD, a neurologist at Mount Sinai Hospital in New York City. “That means that the longer the brain isn’t getting enough blood flow, the more likely there’s going to be permanent injury.” The FAST acronym stands for face, arms, speech, and time.
