We're all getting older every day, and scientific research has shown that starting in our 20s, some brain functions begin a linear decline. But is old age all doom and gloom?

Not at all! While it's true that some functions in the aging brain decline, neuroscientists have discovered that many other brain functions remain stable - or even improve - as we age. Furthermore, nurture plays as significant a role as nature, and there are a number of strategies you can implement to stave off declining brain function, including:

• Incorporating physical activity into your routine
• Eating a healthy diet
• Maintaining a vibrant social life
• Reducing your stress

The science behind the aging brain tells a fascinating - and often counterintuitive - story. Is "aging" a disease or merely a natural occurrence that produces disease-like symptoms? If humans are biologically programmed to survive and thrive, why do we age at all? Is it possible (or even desirable) to "cure" aging altogether?

Delve into these questions and more in The Aging Brain. Taught by a neuroscientist and award-winning professor at the University of Michigan, these 12 eye-opening lectures will give you a wealth of new insights into what happens to the brain over time - as well as strategies to mitigate the effects of aging and enhance your quality of life into old age.

With a mix of scientific research and practical applications, Professor Polk brings cutting-edge science to life. He takes you down to the cellular and even molecular levels of the brain to show you why certain functions decline, how some aspects of brain aging are under genetic control, and what you can do to prolong your health and keep your mind sharp. Aging affects us all, but you have some control over how it affects you.
