I notice that the people who assist POWs or people with parkinsons are referred to as carers in a lot of the publications. My son who is severely disabled with cerebral palsy lives in his own flat assisted by two PAs or peronal assistants. He prefers this term as they assist him with his independence and it feels more empowering than being looked after by a carer.
This may seem a small issue of semantics, but I like his reasoning and I too prefer a PA to a carer!
