  This paper proposes a Minecraft-based system for early detection of
Alzheimer's disease in young adults. Early detection, where spatial navigation
is a crucial key, is regarded as an important way to prevent the disease. The
proposed system is compared with a recent existing and thoroughly studied
system using a game called Sea Hero Quest (SHQ), by analyzing spatial
navigational patterns of players. Our preliminary results show that spatial
navigational patterns in both systems are highly correlated, indicating that
the proposed system is likely as effective as the SHQ system for the detection
task.
