From The New York Times:
During the YouTube forum with the Democratic presidential candidates in July, the first question about health care came from two middle-age brothers in Iowa, who faced the camera with their elderly mother. Not everybody with Alzheimer’s disease has two loving sons to take care of them, they said, adding that a boom in dementia is expected in the next few decades. “What are you prepared to do to fight this disease now?” they asked.
The politicians mouthed generalities about health care, larded with poignant anecdotes. None of them answered the question about Alzheimer’s. Science hasn’t done much better. There is no cure for Alzheimer’s and no way to prevent it. Scientists haven’t even stopped arguing about whether the gunk that builds up in the Alzheimer’s brain is a cause or an effect of the disease. Alzheimer’s is roaring down — a train wreck to come — on societies all over the world. People in this country spend more than a $1 billion a year on prescription drugs marketed to treat it, but for most patients the pills have only marginal effects, if any, on symptoms and do nothing to stop the underlying disease process that eats away at the brain. Pressed for answers, most researchers say no breakthrough is around the corner, and it could easily be a decade or more before anything comes along that makes a real difference for patients.
