Receiving a clot-buster drug before reaching the hospital may reduce stroke disability
A preliminary study shows that giving a clot-busting drug in a mobile stroke unit ambulance may lead to less disability after stroke, compared to when the clot-buster is given after reaching the hospital. The study suggests that ambulances with the personnel and equipment capable of diagnosing ischemic stroke may be worth the extra cost, due to the decrease in patient disability afterward.

Transplanted neurons incorporated into a stroke-injured rat brain
Today, a stroke usually leads to permanent disability – but in the future, the stroke-injured brain could be reparable by replacing dead cells with new, healthy neurons, using transplantation. Researchers have taken a step in that direction by showing that some neurons transplanted into the brains of stroke-injured rats were incorporated and responde d correctly when the rat’s muzzle and paws were touched.
