I was just wondering if anyone has heard of any studies, or has any anecdotal experience to share, about using pheros around dementia sufferers? My dad has a form of Pick's disease and I'll be seeing him over the holidays, so I got to thinking about that. He tends towards depression and agitation, but I wasn't sure if there was some scientific reason to avoid using pheros around someone in his condition or if they might be helpful (thinking here of calming or happy social blends, of course). My mother takes care of him at home so I could get her wax melts, etc. if it wouldn't be a bad idea. Your thoughts are appreciated!
