Brain Research: Long-term aerobic exercise prevents age-related brain changes ♦ Scientists identify main component of brain repair after stroke

Treatment outcomes of brain hemorrhage after thrombolysis for stroke Treating brain hemorrhage after clot-busting thrombolysis for stroke was not associated with a reduced likelihood of in-hospital death or expansion of the hematoma but shortening time to diagnosis and treatment may be key to improving outcomes.
Brain imaging can predict success of large public health campaigns Brain activity in 50 smokers in Michigan was able to predict the outcome of an anti-smoking advertising campaign sent to 800,000 in New York, demonstrating the promise of neuroscience to inform and improve public health campaigns.
Long-term aerobic exercise prevents age-related brain changes A study of the brains of mice shows that structural deterioration associated with old age can be prevented by long-term aerobic exercise starting in mid-life. Structural changes that make the blood-brain barrier leaky and result in inflammation of brain tissues in old mice can be mitigated by allowing the animals to run regularly, providing a potential explanation for the beneficial effects of exercise on dementia in humans
Scientists identify main component of brain repair after stroke Looking at brain tissue from mice, monkeys and humans, scientists have found that a molecule known as growth and differentiation factor 10 is a key player in repair mechanisms following stroke. The findings suggest that GDF10 may be a potential therapy for recovery after stroke.
