THE ADDICTIVE BRAIN  Addiction touches us all. Whether it’s a friend who can’t quit smoking, a colleague afflicted with alcoholism, or a relative abusing prescription drugs, we all know someone who suffers from some form of addiction—we may even have an addiction ourselves.

On the other hand, many of us use substances such as alcohol recreationally, without suffering the physical or psychological symptoms of addiction.

THE AGING BRAIN  Aging is associated with subtle declines in some cognitive abilities, but not others.  As we age, we become a little more forgetful, we get distracted more easily, and we can’t process information quite as quickly as we once did. We also become more susceptible to certain brain diseases, such as Alzheimer’s dementia and stroke. At the same time however, our knowledge, our memory of cognitive skills, our emotional processing, and many other aspects of mental life tend to remain stable or even improve with age. Why is that? And is there anything we can do to help our brains age more gracefully? This course answers these questions, and many others, by explaining what happens to our brains as we age, and by discussing approaches to keeping our minds and brains healthy as we get older.  Learn More
