Unfortunately, most needs occurring with dementia are considered social needs, not health needs and what you need for CHC is health needs. Incontinence, needing help with washing/dressing/feeding, loss of mobility are all considered social needs. Unfortunately, this means that most people with dementia do not score highly enough to meet the CHC criteria. Realistically, it is only really likely to be if there is another health problem (like cancer, or kidney failure), lots and lots of falls, or violent behaviour or reaching end of life that a person with dementia will become eligible.. Ironically, if someone meets the criteria because of high falls, or violence, then they may lose the CHC later when progression of the dementia leads them to being bed bound (and therefore no longer a falls risk) or incapable of violence due to frailty.
A good rule of thumb is - does this need require a qualified nurse, physio, etc to meet the need, or can it be done by a carer? If it can be done by a carer - and most hoisting can - then it counts as a social need and does not score highly enough to count towards CHC.
