Has anyone seen the new Alzheimer's Research ad on tv?

I'm not trying to be a smart adder, but, what is this ad about? The big focus of the ad is how ONE DAY SOMEONE WILL BE THE FIRST TO SURVIVE ALZHEIMERS. WHAT? I don't understand it. I thought keeping your brain function was the goal for this condition. Why focus on surviving only, when the brain function is gone? Am I missing something? I thought that many people live with Alzheimers for many years. It's the loss of memories, loss of organization, loss of judgment, loss of motor skills, loss of mobility, that effects the patients' lives. Why would survival be the focus of this campaign. Maybe, I'm missing something.
