Alzheimer's: Viagra may be linked to lower risk of disease, study suggests - Sky News

A randomised clinical trial will now be set up to try to confirm any benefits to taking Viagra for people with Alzheimer's.

Viagra may be a useful treatment for Alzheimer's disease, according to a new study.

Hundreds of millions of people are affected by Alzheimer's around the world and there is currently no effective treatment.

Lead investigator Dr Feixiong Cheng, from the Cleveland Clinic, said: "Because our findings only establish an association between sildenafil use and reduced incidence of Alzheimer's disease, we are now planning a mechanistic trial and a phase two randomised clinical trial to test causality and confirm sildenafil's clinical benefits for Alzheimer's patients."
