New protein therapy may repair stroke brain injuryRSS Feed

A new protein therapy could help to repair brain injury sustained by stroke patients weeks after stroke.

This new technique, known as anti-Nogo-A therapy, has been compared by scientists at the Loyola University Chicago Stritch School of Medicine as jump-starting the growth of nerve fibres.

Experiments carried out on trained rats saw this therapy administered nine weeks after stroke, with rats recovering 78 per cent of the brain function lost following the ischemic incident.

Currently, the drug tPA usually used to limit the damage of ischemic stroke must be administered within the first three hours for the greatest benefit.

Researchers concluded that the new therapy "may benefit not only victims of spinal-cord injury or patients in the early stage of stroke recovery, but also patients in later stages who suffer from neurological disability due to brain damage from stroke or other causes".

Meanwhile, researchers at Harvard University are confident that they may soon be able to develop a method for assessing brain injury caused by concussion, using magnetic resonance spectroscopy.
