Cancelled Stent Study for Strokes Reveals Implications for Evidence-Based Medicine and Surgical InterventionsI recently read an article in the New York Times that made me think about some issues around how medical testing works. The article talked about a randomized, controlled study that aimed to prevent strokes by implanting a stent into the brain. One group received the stent surgery, while the control group received no surgical intervention but was told to minimize risk factors in their lives. Tragically, the stent seemed to increase the chances of stroke and death in the patients who received them, while the risk factor group was relatively unscathed. The researchers involved were unhappy with the outcome, but noted that this is why research occurs- so you can test things out on a small number of willing participants to discover benefits and consequences before releasing them to a larger population.

At Posit Science, scientists from universities around the U.S. and the world conduct research using our brain training programs, which is how we know they work. When you’re dealing with a software-based training program instead of a pill or a surgical device, you really cut down on the risk of negative side effects, which makes the research a lot less complicated. Reading about the tragic outcome of this stent study made me feel thankful that our products can provide a non-invasive way for people to improve brain health, without risk of serious side effects.

The results of scientific and medical testing should be a key component for people choosing healthcare and wellness options. After all, rigorous research has led to a multitude of proven breakthroughs that help millions of people on a daily basis. At Posit Science we feel strongly that it’s important to offer products that are supported by strong scientific evidence that has reliably demonstrated proven benefits, like those shown in the IMPACT and ACTIVE studies. Without the hard and fast evidence, who can say what works and what doesn’t?
