A study sheds new light on age-related memory loss


Narrator:       
This is Science Today. A team of University of California scientists have new insight into age-related memory loss. Dr. Adam Gazzaley of the University of California, San Francisco and colleagues at UC Berkeley have identified a link between the brain's ability to suppress irrelevant information and its processing speed.

Gazzaley:        They seem to be interacting. The difficulties with suppression are occurring early in your processing. These suppressive mechanisms are not coming online fast enough, so information is just sort of getting in there and before you have the chance to actually block it out, too much information is getting in.

Narrator:        This research will help scientists develop ‘brain fitness' exercises.

Gazzaley:        We have collaborations looking at different pharmaceutical interventions  as well as looking at brain fitness exercises to see if we can come up with better physiological markers of the brain to characterize how these interventions are working; if we can understand the measures that are changing in the brain, we might have better end points and functional neuromakers to try to manipulate these measures back to a younger, healthier, more efficient state.
