Due to his stroke he has a stroke related dementia, his doctor has prescribed a medication (Haloperidol Tablets 0.5 mg.). Yesterday morning, while I was sleeping he managed to unlock the front door, go outside (in his underwear) walk around the corner of our home and attempted to get in our kitchen door. It was locked, he started to pound on this door, finally woke me up and I got him inside. Could this medication caused him to do this? He has never done this before. Also, he normally has a problem unlocking the front door.
