Some of the early stage patients are still active and like to go out, which is not a bad thing, but they often overestimate their ability and think that they can learn how to get to and from a certain place after one or two times of verbal instruction from others. In fact, even if they can learn how to do it, it takes a long time for them to practice and be guided by others. In addition, they have to deal with unexpected problems on their own during the journey, such as diversion of routes, change of landmarks or shops that they are used to recognizing, etc., which may cause additional difficulties and lead to getting lost.
