From ED to AD: a drug repurposing success? How a performance-enhancing drug is giving insight into dementia

Recently, researchers at Cleveland Clinic’s Genomic Medicine Institute published an article in Nature Aging which has caused quite a stir in the medical community and media – in the article these researchers report that an analysis of over 7 million people, spanning six years, found that those taking the Erectile dysfunction (ED) drug sildenafil (marketed as Viagra) were 69% less likely to develop Alzheimer’s disease (AD). This being said, there are some important caveats to this study – and so, although media reports on this study include lines such as “the little blue pill could soon be prescribed to tackle dementia”, more realistic implications should be the takeaway (but not less exciting!).

The Argument for Aging as a Disease

When asked how someone died, ‘they died of old age’ is an acceptable answer – it is given as the cause, like a heart attack, stroke, or cancer. However, unlike these other answers, aging is not classified as a disease. But should it be? This article will discuss the debate over whether aging should be considered a disease, the arguments for and against such a classification, what it would mean from a clinical standpoint, and how it would transform the pharmaceutical and nutraceutical industries.

The Lifespan Assay Survival Kit [Whitepaper]

The nematode Caenorhabditis elegans has provided remarkable insights into the biology of aging. The precisely measurable lifespan of worms has proven to be an efficient tool to assess the impact of various genetic, physiological and environmental factors on organismal aging. Lifespan assays can be labor intensive and time consuming. In this article, we will highlight the critical considerations that could make or break your lifespan assay. Our aim is to help you interpret a variety of different procedures by emphasizing the crucial considerations to ensure the success of running a lifespan assay.
