Sean O'Grady is one of more than 5 million Americans living with Alzheimer's disease. His family takes care of him at home.
"He worked so hard. He deserves this from us now."
At 68 years old he is bed-ridden and he doesn't recognize his wife or daughters.
"It's very hard to watch...I don't know how my mom does it. I know how hard it is for me. I can only imagine how hard it is for her," says daughter Siobhan.
According to a new report from the Alzheimer's Association 1 in 3 seniors die with the mind-destroying disease or another form of dementia.
"Over 80,000 people a year die from Alzheimer's disease, unfortunately many many more, over 450,000 die with Alzheimer's," says Maria Carrillo.
The report found the death rate for Alzheimer's rose 68% during the past decade. And unless researchers find a way to prevent it or treat it, that number is expected to climb even higher.
Health care costs are estimated to be $203 billion this year. And then there is the emotional and financial toll the disease takes on the 15 million caregivers.
"He has to be cleaned, he has to be changed, he has to be fed."
Sean's wife Kay hopes to keep him out of a nursing home.
"I want to see the journey through. Keep Sean as comfortable as we can and hopefully that he doesn't suffer."
His daughter has another hope - she wants a cure.
