What Does Alzheimer’s Do To the Human Brain?

Alzheimer's has been called the epidemic of our century—every 66 seconds someone in the United States is diagnosed with Alzheimer's.

SICK is a new series that looks at how diseases actually work inside our body. We'll be visiting medical centers and talking to top researchers and doctors to uncover the mysteries of viruses, bacteria, fungi and our own immune system. Come back every Tuesday for a new episode and let us know in the comments which diseases you think we should cover next.
