Brain Damage from Stroke Reduced with Natural Protein Given up to 12 Hours Later
Catharine Paddock, PhD
Giving mice a naturally occurring protein called
alpha-B-crystallin that is made in the body, shrank brain lesions caused by
stroke, even when treated 12 hours after the event, according to a new study by
Stanford University School of Medicine researchers published early online
today, 26 July, in the Proceedings of the National Academy of Sciences.
The study is important because it gives hope that the window of treatment can
be extended, since the only approved current drug, a clot-buster, has to be
given within 4.5 hours and then only after patients have undergone a scan to
make sure the cause is a clot and not bleeding.
National Stroke Association’s mission is to reduce the incidence and impact of stroke by developing compelling education and programs focused on prevention, treatment, rehabilitation and support for all impacted by stroke.
