Most people who have strokes don't act quickly enough to get the clot-dissolving treatment that can limit brain damage, a new study finds.
Rose and her colleagues studied data on 15 117 people treated for strokes at 46 hospitals in North Carolina between 2005 and 2008. Treatment for an ischaemic stroke, in which a clot blocks a blood vessel in the brain, is an injection of clot-dissolving tissue plasminogen activator (tPA), but that is effective only in the first three hours after a stroke occurs.
