Diabetes Drugs for Alzheimer’s Disease?

A recently published paper┬áreported that combination of three diabetes drugs (GLP-1, GIP, and glucagon) improved memory in a mouse model of Alzheimer’s. This is quite remarkable, but not shocking.

There are several competing theories of Alzheimer’s disease. There is the all-but-discredited theory of beta amyloid. I would like to still believe in this theory, having been a proponent of this theory for several years at Elan. It is a compelling theory for several reasons. First, the familial forms of Alzheimer’s disease have mutations that increase beta amyloid. Second, you can cause Alzheimer’s by injecting beta amyloid into the brain. Third, transgenic mouse models targeting beta amyloid can reproduce some of the symptoms of the disease. But unfortunately, data from multiple studies have shown that the theory is incorrect. It is difficult to admit that so much beautiful science (much of it done at Elan) can be so wrong but I think it may be. Continue reading “Diabetes Drugs for Alzheimer’s Disease?”
