Study Suggests Erectile Dysfunction Drugs May Reduce Alzheimer’s Risk in Men”
A recent study proposes a potential link between the use of erectile dysfunction drugs, such as Viagra, and a reduced risk of Alzheimer’s disease in men. The research, which analyzed prescription records of over 260,000 men, found that those taking these drugs had an 18% lower likelihood of developing Alzheimer’s compared to those not using them.

Dysfunction Drugs
While promising, the study does not establish a definitive causal relationship, emphasizing the need for further research to explore the potential benefits and mechanisms of these drugs in relation to Alzheimer’s risk.
Originally developed to treat conditions like high blood pressure and angina, erectile dysfunction drugs impact a cell-signalling messenger that may have connections to memory. Additionally, these drugs are known to affect brain cell activity, with animal studies suggesting a potential protective effect on the brain. The study, conducted by researchers from University College London, focused on men with erectile dysfunction, comparing those prescribed these drugs with those who were not. Over five years, the group using the drugs had a lower incidence of Alzheimer’s, suggesting a potential association.
While the study’s findings don’t conclusively prove that erectile dysfunction drugs directly reduce Alzheimer’s risk, they open a new avenue for research into the relationship between these medications and dementia. Lead author Dr. Ruth Brauer emphasizes the need for further investigation, optimal dosage exploration, and a potential trial involving women to gain a more comprehensive understanding.
Experts recognize the significance of the study but underscore the necessity for more concrete evidence regarding how these drugs affect the brain. Professor Tara Spires-Jones from the University of Edinburgh notes that the study provides compelling evidence for further research, while Dr. Francesco Tamagnini from the University of Reading suggests the need for thorough testing of hypotheses related to the therapeutic effects and increased blood flow associated with these drugs in relation to Alzheimer’s prevention.
