This issue needs careful evaluation and is certainly a safety concern. The following points may help you decide.

Does the person with AD:

o                                become confused or unpredictable under stress?

o                                recognize a dangerous situation; for example, fire?

o                                know how to use the telephone in an emergency?

o                                know how to get help?

o                                stay content within the home?

o                                wander and become disoriented?

o                                show signs of agitation, depression, or withdrawal when left alone for any period of time?

o                                attempt to pursue former interests or hobbies that might now warrant supervision such as cooking, appliance repair, or woodworking?

You may want to seek input and advice from a health care professional to assist you in these considerations. As Alzheimer's disease progresses, these questions will need ongoing evaluation
