See how the cognitive changes of aging relate to the biological changes discussed in the previous lectures. It turns out that regions of the brain associated with processing speed, executive function, and episodic memory are more susceptible to aging, which may explain why these cognitive functions are particularly susceptible to decline.

Turn from the brain's structure to its activity. After reviewing how we study brain function via fMRI, Professor Polk shows you how brain activity changes as we age-and how these changes impact our memory, our ability to multitask, and more. Then, learn some good news about how the brain compensates for these changes.

Finally, an in-depth look at the things you can do-and the things you should avoid-to delay, slow down, or possibly prevent Alzheimer's disease and other disorders of the aging brain Billions of dollars and decades of Alzheimer's research targeting the hallmark plaques and tangles in the brain have failed to produce a meaningful treatment for people with the disease. Drawing from the extensive research into ketogenic dietary intervention that dramatically...
