I found this article the other day and felt that it really did a good job of showing what happens in a lot of cases when someone finally moves into an assisted living community. Having worked in them myself I have seen this same story, different names. Senior is at home, lonely, not eating properly, not taking medications correctly, not safe. Usually something triggers the acceptance of the move. And often times, this will happen. The senior will flourish with proper medication management, good nutrition and socialization. Of course this does not happen 100% of the time, but if you can do a good job of researching/picking the right place, it just might.
Here is a link to the story, When is Assisted Living the Right Solution for Elder Care?
