I need some helpful suggestions. Dad was diagnosed about 15 yrs ago and his impulse control has recently all but disappeared. He has now started wandering in strangers gardens, rummaging through skips and recently just wandered into an aquaintants house and into her sitting room unannounced. He has followed people home before and been found in the hallway of their flats but this time he wandered into their back garden and into their house without knocking. Has anyone else experienced this sort of behaviour? Have tried explaining that it's not on but he doesn't seem to be taking it in.
