Stroke drug may fight Alzheimer's
A drug used to treat ischemic stroke in some Asian countries has shown promise in treating the degenerative effects of Alzheimer’s disease in mice, according to findings published in the Proceedings of the National Academy of Sciences.
The drug, Edaravone, was able to improve learning and memory functions in mice with Alzheimer's disease, according to a team of researchers in Australia and China. Their analysis showed that the drug seemed to be able to suppress the production of amyloid beta plaque--a major factor in the degeneration of nerve cells. It also inhibited the process by which tangles accumulate in brain cells and disrupt brain function.
The researchers emphasized, though, that because the drug's impact on Alzheimer's in humans has not yet been tested in clinical trials, people should not attempt to use it as a treatment of Alzheimer's.
