But this second cost is alredy included in the article: The cost of living at home is also very high,[17] specially when informal costs for the family, such as caregiving time and caregiver's lost earnings, are taken into account. When it is calculated how much money costs caring for an AD person and how much money is lost is already taken into account that a person with dementia and specifically with AD has to be closely followed. The thing is that it is not only because of wandering. It is also because he may endanger himself in the kitchen or bathroom, he is not able to take his meds adequately, etc. So I do not really see the point of specifically talking about wandering when the costs wandering brings can not be separated from the costs brought by other symptoms of dementia.
