Diabetes drug improves memory

[Marco]

In an Alzheimer's mouse model at least :

"Using this drug appears to restore the neuronal signaling required for proper cognitive function," said UTMB professor Larry Denner, the lead author of a paper describing this work now online in the Journal of Neuroscience. "It gives us an opportunity to test several FDA-approved drugs to normalize insulin resistance in Alzheimer's patients and possibly also enhance memory, and it also gives us a remarkable tool to use in animal models to understand the molecular mechanisms that underlie cognitive issues in Alzheimer's."

Which reminds me of a description of Alzheimer's I read a while back as 'Type 3 Diabetes' or 'Diabetes of the Brain' :
