Very good advice from Open Eyes.

Would like to add, is S receiving support from appropriate agencies/charities which specialise in dementia support? Might there be specific peer support groups he can access which other people who are going/have been through the same thing attend?

Other than that I do have to say I have misgivings about the ethics of writing an online journal about a support group you attend. I volunteer in peer support and confidentiality is a big consideration to us.
