Did you know that a simple mobile game could revolutionize the early diagnosis of Alzheimer’s disease? Sea Hero Quest has collected data from millions of players to create a “map” of normal human navigation opening up a new path in the fight against cognitive decline.
One of the earliest and most telling signs of Alzheimer’s is spatial disorientation, patients begin to get lost and lose their internal “map” of their surroundings. To detect this decline at a very early stage, we need to know precisely what counts as normal navigational ability. And that requires a vast amount of data. Researchers solved this data gap with the mobile game Sea Hero Quest.
The concept is simple: players steer a boat, navigate through a map, and return to the starting point while the app records how they do it.
This citizen science project has produced astonishing results: data from more than 4.3 million people have been collected. The huge database of so-called “normative benchmark data” can be used for personalized cognitive diagnostics and to better understand what “normal” performance looks like.
Researchers were able to map how spatial orientation declines with age, and they also confirmed that, on average, men perform slightly better in navigation tasks.
With the performance data from Sea Hero Quest, scientists can now more accurately identify subtle, early deviations in people who are still symptom-free but genetically at risk.
Fighting dementia effectively means when interventions such as lifestyle changes or therapy, before severe symptoms appear.
Digital data is helping researchers reach a new milestone in the early diagnosis of Alzheimer’s disease, improving the future quality of life for millions of people.
