Would you want to know if you'd inherited a better-than-average chance of developing Alzheimer's?

Genetic testing can now provide some clarity, if not a crystal ball. And that's tempting for caregivers or anyone who's had a front-row seat on a loved one's Alzheimer's and the tremendous life changes the disease brings.

Like me, for instance. I muse about being tested myself every time I read about a new gene being linked to Alzheimer's -- as happened in July -- or as I follow research involving gene therapy. (A multi-site Phase 2 clinical trial is now enrolling.) My father has an Alzheimer's-like dementia, and my mother's mother died of complications of Alzheimer's.

So how am I tilting?
