1. Lack of direction: Due to a weak sense of direction, individuals may easily lose their way in complex or new environments, leading to difficulty finding their homes.
2. Memory problems: When memory declines or attention is not focused, people may forget their way home or the specific location of their home, especially the elderly or those with certain cognitive impairments.
3. Environmental changes: If residential areas frequently undergo road construction, building renovations, etc., environmental changes may make familiar routes unfamiliar, increasing the possibility of not being able to find home.
