For people with cognitive impairment, wandering is a problem that cannot be completely cured. Caregivers can only apply different methods to minimize the chances of wandering, so measures to prevent wandering must be a priority. Some caregivers shared that why some methods of wandering prevention do not work for the elders under their care but are effective for other elders? In fact, there is no single method that is foolproof, and it is necessary to take into account the changes in the condition of the elderly's cognitive impairment, personal preferences and habits, etc. As long as we keep trying, we will be able to find the right prevention method.
