Viagra could be used to treat Alzheimer’s disease, study finds | Alzheimer's | The Guardian

Viagra could be a useful treatment against Alzheimer’s disease, according to a US study.
[Researchers] found sildenafil users were 69% less likely to develop Alzheimer’s disease than non-sildenafil users after six years of follow-up. To further explore the drug’s potential effect on Alzheimer’s disease, researchers developed a lab model that showed that sildenafil increased brain cell growth and targeted tau proteins, offering insights into how it might influence disease-related brain changes. The findings were published in Nature Aging.
