Researchers work to keep the aging brain healthy

This is Science Today. How does one keep an older brain healthy? Neuroscientists at the University of California, San Francisco are working on ways to improve brain cognition, memory and attention. Dr. Adam Gazzaley, director of the Neurosciences Imaging Center, says they're looking at different pharmaceutical interventions, as well as ‘brain fitness' exercises to see if they can come up with better physiological markers of the brain to determine if these interventions are working.

Gazzaley:        I think there is a very large recognition of how important it is to keep the older brain healthy. And given the recent increase in the number of industry ventures into brain exercises and cognitive enhancers, I think that once we get through the threshold of looking at how these things work independently and find better neuromarkers for them, then the interactions of the two will be really fruitful. So, hopefully over the next five years, I would hope that we start having a stronger foothold in how we can help the aging brain.
