Dead bolts on all doors!
I often read or hear about dementia patients leaving their homes and wandering outside and family members have to go searching for them. There is absolutely no excuse for this! All it takes is for the caregiver to call a locksmith, and he will gladly oblige with a dead bolt and several keys, and of course the patient will never have a key; it will not be possible to leave the house. I don't know why all caregiver spouses don't automatically do this before the wandering begins. I have three doors in our house that needed dead bolts, and it cost me just over $700, but it was well worth it because I can sleep peacefully now knowing that there is no way in the world my husband cannot open any of the doors while I'm asleep. He has tried and has asked for a key, and I told him that I did this for his own safety and for my piece of mind. He has finally accepted my decision.
