they are supposed to be trained. and other training is mandatory every year. moving and handling, safeguarding, health and safety is the umbrella.if a person is to care for someone with dementia, they need to know something about the different types and the different typical characteristics. person-centred care most importantly.giving choice of clothes, meals and times that the person like to choose. yes i worked in a care home and yes i was well trained even in challenging behaviour. we were taught different dementias and the different techniques to try with challenging behaviour. i didnt for one minute know it all or pretend to know it all but i had a foundation to build on to be able to care for people to the best of my ability. how does anyone know if a person is healthy or not even if they have few medicines, i understand that doctors spend a lot of years to be qualified as a doctor and carers are not doctors or anywhere near a nurse. there are care qualifications which are needed.
