Where is the cure for Alzheimer’s?

In other words, more than a decade-and-a-half since my father’s death, the more than six million American families with a loved one with Alzheimer’s are facing exactly the same fate as mine. While treatments for diseases such as many cancers, some autoimmune disorders like multiple sclerosis, and HIV have undergone revolutions during this period, Alzheimer’s has defied all attempts at altering the course of this brain-robbing disease. The treatments that are always promised are still around a distant corner.

I have covered medical news for decades. I am a big believer in medicine’s triumphs—so was my dad. But why did medicine have nothing to offer my family and so many like ours?

I set out to discover why.
