Headlines make scientific breakthroughs seem sudden, but, in truth, the real advancement of science is more like the construction of a pyramid. Each block of the pyramid represents a hypothesis that attempts to explain an observation in nature that has been tested experimentally. Depending on the results of the experiment, the hypothesis is either confirmed, revised and tested again, or rejected. Each block adds to a new layer of the pyramid, each layer built on those below. No single study is likely to crack the code for an immediate Alzheimer’s cure, but each one contributes to our understanding in ways that I am confident will eventually lead to more effective treatment and prevention. Even if it’s not in time for me.

Clinical trials are the bricks and mortar of medical science, and if having Alzheimer’s means I’ve had to step away from any professional involvement with them, it also opened up a new opportunity to stay involved.
