Decline in judgment is one of the causes of lostness. This deterioration leads the cognitively impaired person to make wrong decisions on how to use transportation properly, including choosing which transportation route to take, deciding which stop to get off the bus, and identifying the way to go after getting off the bus. A mistake in any one of these steps will result in the elderly getting on the wrong bus, getting off at the wrong stop or going the wrong way, which will lead to failure to arrive at the destination smoothly and cause the person to get lost.
