A recent ranking of existing drugs and vaccines has identified Viagra as one of the best options to protect individuals against Alzheimer's disease. The review, conducted by a panel of 21 experts, found 80 candidates with potential in treating the neurodegenerative disorder. Three of these included Sildenafil (Viagra), Zostavax (a shingles vaccine), and riluzole (a drug used to treat amyotrophic lateral sclerosis). These treatments have been linked to Alzheimer's prevention by previous studies. However, further research is required to confirm these drugs' ability to prevent or reverse Alzheimer's in human patients.
