BSL is developed (not exclusively) for the deaf. Makaton more (but not exclusively) for the hearing. They are not in competition. This can be misunderstood.
There are over 200 dementias. Some people can live with dementia for many years and medication is promoting this.For them the decline is slow and they are open to developments that may help them in the future. Makaton fits for some people. In some cases of dementia where the body and brain are deteriorating at different speeds then the body deteriorates faster than the brain so to talk, to write is physically impossible but to point, to indicate is possible.
As I've said before, Makaton is fluid, it can be adapted to the individual. They may only need to utilise a tiny part of the whole.
People on this thread have said they are/have used Makaton with those living with dementia and it's been beneficial. I have seen it benefiting those living with dementia. That, to me, is worth more than any academic paper, and l find it highly frustrating that you extol words rather than action.
I wish you well.
Yes, I prefer properly researched academic papers to random, anonymous people on a social media site.
A number of people on this thread have already pointed out why Makaton is not a good solution for all those with dementia.
I don't have much experience of people with dementia, although my children give me regular updates about what's happening with their grandmother (my ex's mother). However, I am a trained language teacher. Teaching a language involves understanding how people learn languages. I have also studied language acquisition (including children with SEN), so have some idea how the brain works when acquiring language. Dementia isn't just a reversal of language skills. As some have said, language is often retained until the end of life - it's something more fundamental which is causing problems.
