A worldwide research effort is underway for finding a treatment option for hyperphagia, the most common genetic cause of life-threatening childhood obesity. 

Nearly half of 50- to 64-year-olds think they’re likely to develop Alzheimer’s disease or another form of dementia, but few have talked to a doctor about what they can do to reduce their risk, and many use unproven tactics.

Most adults ages 50 to 80 say they support its use with a doctor’s recommendation, but they want more research.
