The race to find a treatment for Alzheimer's disease and other forms of dementia is littered with false starts, dead ends, and fiery crashes. That caveat aside, there has been some promising research indicating a class of drugs originally created to control diabetes and fight obesity could also help slow down the progression of Alzheimer's. A new study in mice, published recently in Brain Research, now suggests we could supercharge this cognitive protective effect by using a drug that interacts with three hormones connected to diabetes.
