Hi, I care for my Mum and Dad who both have dementia. My Dad was always meticulous about hygiene, but his personal hygiene is non existent now and I'm at my wits end to know how to support him with this. He insists he's showering and changing his clothes regularly, but he hasn't actually showered or washed this year, although he believes he has. He is filthy and his clothes and body are also really dirty and smelly. He just doesn't see this. Any advice please? Debs
