Hi there - can I just say the McMillan advisers told my parents that they weren't entitled to anything (they are 76 and 79 yrs), but people advised them to ask again and the council sent a Welfare Rights Adviser to see them and to help complete the forms.
My mum has now received attendance allowance, backdate to the day she applied and apparently my dad will qualify for carer's allowance too, but he hasnt been notified of this yet.
They were both absolutely flabbergasted as they have never been given anything and very little help all the way through their lives and they live on basic pension.
I'm so pleased for them.
Check to see if your DWP / Council dept whatever, has a Welfare Rights adviser and pursue them.
