Viagra reduces the risk of Alzheimer's disease.
Viagra can reduce a man's chance of developing Alzheimer's disease
A study suggests that men who take the little blue pill to treat erectile dysfunction were 18 per cent less likely to develop the degenerative brain condition, compared to others with the same medical issue who were not prescribed the medication.
The findings are only observational - meaning that it cannot prove that Viagra was responsible for the decreased risk - but the researchers feel that the link is worth further investigation.
An explanation could be that Viagra and other drugs increase blood flow in the brain, which has a protective effect on the organ.
Matthew Adesuyan, an author of the study at the University College London (UCL) School of Pharmacy, said: "The results are encouraging and may point to a new way to reduce Alzheimer's risk."
