Since the invention of functional brain imaging in the early 1990s, this instrumentally and computationally expensive methodology has captured our interests in visualizing the working mind, especially that of super-ageing brains. Because neuroimaging research is costly, various communication strategies are deployed to increase its visibility and fundraising success. Through a historical perspective on the representation of healthy ageing in the media, we examine the methods of communication (media logic) and the cultural interdependencies between media, research institutions, and health funding politics (mediatization), which magnify the profile of brain imaging in advancing the science of healthy ageing. Examples of hyped messaging about healthy-ageing brains underline the risk of visual ageism — a prejudiced and stereotypical view of what a good or bad older brain looks like. We argue that hyped mediatization can alienate older adults from participating in a line of research that might stigmatize them.
