Dr. Ralph Sacco has his own way of thinking about time:
“Time is brain,” says Sacco, a neurologist at the University of Miami and chair of a registry that collects hospital data on what happens to stroke patients in Florida and Puerto Rico.
During a stroke, he says, “every minute, millions of brain cells die and we can't salvage them. You need to get urgent attention ... you need to get to a stroke center.”
For most strokes, the window for treatment is six hours. Depending on the kind of stroke, treatment can be effective within 24 hours.
