A New Review of New Ways to Improve Brain Health

For decades, we’ve been waiting on the scientific community to find a cure for Alzheimer’s—but very little progress has been made. The first drug used to treat the symptoms of Alzheimer’s was Cognex (tacrine), which was approved in 1993; and the most recent was Namenda (memantine), approved in 2003. That means that in the past…

New Year, New BrainHQ

One of our goals here at Posit Science is to make BrainHQ the best brain training program in the world. To do that, we have worked with hundreds of scientists, making sure our scientific foundation, design, and research is top notch. But there’s another group of people that’s equally important to listen to: people who…

The Evidence for Brain Training – Seeing the Whole Picture

Brain training works! Brain training doesn’t work! Every week, I see a new headline in the news about brain training, and they reliably go back and forth between these two extremes like the tick-tock of a clock. Why the back and forth? If a study shows that brain training works in one week, how can…

Brain Training and Its Critics

When I was in college, I took a lot of science courses. Really, a lot — maybe even too many. And mostly what they taught me was how scientists believed the world worked — right then, as of the early 1990’s. Luckily for me, my college roommate took a somewhat broader curriculum, and much to my benefit, we talked…

A Criticism Of Brain Training – And An Answer To It

An interesting paper came across my radar week – “Placebo effects in cognitive training” published in PNAS (with a paywall, unfortunately). In this paper, the authors investigate the effect that people’s expectations might have on the results of brain-training experiments. Every research study needs to recruit people to participate, and a common way is to…
