It restricts exit for the Alzheimer's victim, by the time a hook and eye are needed they have someone at home with them 24 hours a day. A good shove by someone able bodied will pop the eye from the door frame in an emergency.
My thoughts exactly. The Alzheimer patient will start to cry before they would pull hard enough on the door for the eye to come out. Alzheimer patients get frustrated very easily and give up quickly.
