One of the many problems which happens whenever there is a patient with dementia is that they will tend to want to wander about. This has less to do with desire and more to do with the fact that they are not able to remember where it is that they are or how they came to be there. This is when you will need to help in making sure that they will be able to stay in a more confined area. It is not trapping them. It is protecting them from themselves.
The biggest danger is not that these patients will forget how to get home. The biggest concern is that they will walk directly into traffic. Because they lack the ability to remember how their environment works, they will forget when they should be walking into a street and when to avoid cars. This can cause problems in which there is an accident in which your loved one is involved in of no fault of their own.
The beat way that you will be able to make sure that you will be able to protect your loved one is to make sure that they are able to stay within their own home. The medical care program that they are on will generally cover the cost of a certified nurse practitioner which can come to the home. This will help in making sure that they are getting the care that they will need along with another pair of eyes to help them stay within the home.
There are many facilities within each city which will allow you to submit your loved on into a program in which they will be able to get the care that they will need while maintaining a residence in a facility which will not allow them to wander off. Keep in mind that you will need to bring as many items as possible from the home so that they will be able to get the kind of environment which will help them to feel as if they are at home and not in an unfamiliar place.
