Comparative analysis of the software techniques available for protecting Alzheimer patient

Alzheimer is a kind of a disease that causes problems in thinking, behavior and memory. It is the most common form of Dementia (general term commonly used for the memory loss). This is a very dangerous disease as a victim does not realize that what action can cause harm to him or others too. He even tends to forget his friends, family and close relations. The victim also suffers from the problems like hallucinations, wandering, aggressiveness, eating as well as sleeping disorders. These kind of people are very difficult to handle and the major challenges faced while handling them is to cope up with their behavior and the personality changes that occur time to time. So, as a caregiver one cannot change the patient's behavior and their personality instead try to employ the strategies to change or accommodate with their issues. The main problem comes when the Alzheimer patient leaves home without a caregiver. Various methods have been adopted to prevent the patient from wandering. In this paper an comparative analysis is performed on the available software techniques for their protection. Most of the techniques are not cost efficient and difficult to install.
