A mobile game has been developed by University of East Anglie (UEA) and University College London in the UK; and Deutsche Telekom which can detect whether you are at risk of being affected by Alzheimer's Disease.
The Sea Hero Quest Game has several mazes for the player to navigate and so far 27000 people in UK in the age group of 50-70 years have played it. A lab group of 60 participants were identified for genetic testing. Out of this 31 had the APOE4 gene. Such gene carriers are more likely to develop Alzheimer's disease and they play the Sea Hero Quest game differently from those who don't have the gene. Such people fared poorly in spatial navigation tasks and took less efficient routes to checkpoint goals.
Such people with spatial navigation difficulties may not show any memory problems which comes only at later stage of onset of Alzheimer's.
