I think that's a bit harsh on the professionals, maybe they should just own up and say there's nothing they can do to help you as there is no cure or solution to your problem that they can offer.
There's a thread on here about people taking their shoes and socks off I saw 2 people do that today in a care home, yesterday a lady went in the bathroom and walked back in naked, the staff were distracted as one of the men was peeing on a plastic plant at the time, what do you do?
It isn't that your not being deprived of help there simply isn't anything anyone can do, you can re-educate someone with AZ or give them Cognitive Behavioural Therapy to stop them, I hate the ones who pick at themselves and the man who keeps punching himself in the forehead, the phantom peers, the pad throwers, the screamers...the list goes on but it isn't that the professional won't help it's that they can't help.
I don't know if I would want to be a "healthcare professional" when all you want to do is help these people but there is no help available, there is literally nothing you can do to help I just think I'd find it too demoralising as a job the only thing I could do is empathise with the carer but that apparently would make me "patronising" but it's all I would have to offer.
