International research involving University of Otago researchers has found a new neuronal signalling pathway which could lead to improved treatments better able to limit the brain damage sustained after a stroke has taken place.
The research, published in prestigious journal Nature, looked at brain damage in mice following stroke. It found that using a drug to inhibit build up of the neurotransmitter GABA reduced damage in brain regions near those affected by the stroke, and significantly enhanced recovery of mobility. Importantly, outcomes improved when treatment was delayed by several days, unlike currently available therapies which must be administered within hours of stroke.

Earlier this week, the University of Auckland highlighted a separate study that aims to better predict a patient’s chances of mobility recovery following stroke.
