Metformin is a diabetes drug that is readily available via prescription. Can it be used to treat Alzheimer's disease?
Alzheimer's Reading Room
However, it might become a potential treatment for Alzheimer's. But, not any time soon.
The interesting and exciting part of this research is how it unfolded. The researchers showed that metformin could enhance the development of mature nerve cells from stem cells. This works with human brain cells in the laboratory, and in mice. This has not actually been tested in humans.
In addition, this is not Alzheimer's research. However, you could make a giant leap and hypothesize that this might work with neurodegenerative diseases like Alzheimer's.
There might be some excitement in the Alzheimer's community because you can buy this drug right now, and it appears that it does enhance memory in mice.
Keep in mind, there is no evidence in any of this research that Alzheimer's could be reversed. It appears that the drug can help existing brain cells to divide and produce new brain cells.
The video below is very good, and walks you right through the process of this research up to this point. It is worth viewing.
