As Alzheimer's disease continues to progress, your loved one may eventually become so frail that he or she is at risk of falling by merely getting out of their bed, chair or wheelchair. It now becomes necessary to notify the caregiver of any and all such attempts to move. Restrictions such as railings and seat belts should be avoided. Imagine how you would feel, tied to your wheelchair or confined to your bed, not even able to roll over. Alarms that can notify you immediately are the next step in order to protect your loved one in these situations.
