New drug could protect brain from stroke damage

A new drug appears to protect the brain against damage from stroke, even if administered hours after the stroke occurs, according to a new study in monkeys.
Monkeys given the drug had less dead brain tissue and showed more improvements on tests of brain function after a stroke, compared with monkeys that did not take the drug.
Testing on primates was important because, over the last half-century, there have been more than 1,000 drugs aimed at preventing brain damage that have failed to work in people, even though they worked well in mice or rats, said study researcher Dr. Michael Tymianski, of the Toronto Western Hospital Research Institute in Canada.
