Hello, my Dad has mixed dementia and has started wandering. He used to travel as a sales rep and appears to be reverting back to that. This morning he told my Mum at 6am that he was going 'up north' to meet people. He had no idea how he was getting there (he no longer has a licence and no car). Does anyone have any advice on how to stop him, please? I know you should always try to agree with what they say but it would be unsafe to have an 83 year old out and about. I asked him to plan his trip...route, visits etc in an effort to delay him but he just wants to be out. Mum even offered to go with him but he thinks we're treating him like a child. We're just trying to protect him. We have alarms on all the exit doors and a bolt but then he just gets cross and argumentative.
